A New Species

Head 0·83 mm. long, shiny orange-yellow, with the clypeus and the adjoining portion of the frons shiny black. Eyes black, prominent, extending laterally beyond the anterior lateral margins of the pronotum. Rostrum brownish black, extending to, but not surpassing, the posterior coxae; lengths of the joints: first 0·53 mm., second 0·76 mm., third 0·4 mm., and fourth 0·6 mm. Antennae brownish black, the third and fourth joints somewhat paler; first joint slightly incrassated, length 0·83 mm., second 2·0 mm., third 1·83 mm., fourth 1 mm. Pronotum shiny orange-yellow, posteriorly somewhat suffered with dark brown; length in middle 1·4 mm., breadth at anterior margin 0·8 mm., at posterior margin 2·0 mm.; sides straight, posterior margin moderately convex. Scutellum shiny black, finely rugosely punctate and regularly covered with pale depressed hairs; length in the middle 1·3 mm. Corium and cuneus similar in colour and pilosity to the scutellum; membrane dark smoky brown, veins shiny black, passing the apex of the abdomen. Sternum: mesostethium and metastethium black, the metastethial orifices and the surrounding areas very pale yellow: undersides of abdomen shiny black, covered with very fine pale hairs. Legs: coaxae blackish brown; femora dirty orange-yellow, suffused at base and apex with brown; tibiae dark brown, armed with fine black spines; tarsi black, strongly pilose.

General Appearance

Catocala Sara, n. sp.Expanse 3.10 inches. A form in size and general appearance resembling C. Aspasia, Streck., but having much darker colored fore wings, besides other points of difference. Primaries blackish gray from the base to the t. a. line, along the posterior margin to the subterminal line, and from this in a broad band to the costa, the inner part of this band running along the inner side of the reniform. This color is formed of a black or brownish black ground, sprinkled with white scales. This leaves a pale space between the stigmata from the median vein to the costa, and the whole end of the wing beyond the dark space spoken of. T. a. line indistinct, of the ground color, but with less white scales; t. p. line distinct anteriorly, one large and one small tooth opposite the reniform. Subterminal space scarcely tinged with brown, the subterminal line white with a sprinkling of black scales. Orbicular indistinct, black with a few white scales, reniform with a few white scales and an annulus of gray, Terminal space gray. Secondaries rosy red, the median band very much as in the form Walshii, not reaching the inner margin, a little constricted opposite the disc, beyond this a little enlarged, after which it narrows to less than half tlie costal width. Terminal line like Walshii, with an internal excavation before the anal angle that reaches half through the band.

Culex siphonalis, sp. nov.—♀. Head brown, occiput covered with pale yellow scales, antennæ brown, basal joint and two following ones testacesou; proboscis pale brown, with dark brown scales scattered over the surface, covering the apical fourth; palpi dark brown, with minute terminal joint oval in form, pointed at the apex and slightly spiny. Mesonotum covered with pale yellow and brown scales at the sides and with a median vitta wholly of brown scales, the pale yellow scales sometimes forming a narrow border to this vitta; scutellum brown, with yellowish-brown bristles on the posterior margin; metanotum evenly brown; pleura brown, clothed with patches of dirty white scales; halteres yellowish-white, black at the apex.

Threshold Doses

Dutch-belted 1 to 2.5 kg anesthetized rabbits were exposed to either xenon or argon laser light administered in a broad band, designed to cover large areas of the retina. For laser exposure, the pupil was dilated with atropine sulfate 1% and pheny lephrine 10%. All of the laser generated power was within a band centered at 5145.0 Anstroms. Established threshold for 4 hour exposures to laser irradiation are in the order of 25-35 microwatts/cm2. Animals examined for ultrastructural changes received 4 hour threshold doses. These animals exhibited ERG, opthalmascopic, and histological changes consistent with threshold damage.One month following exposure the rabbits were killed with pentobarbitol. The eyes were immediately enucleated and dissected while bathed in 3% phosphate buffered gluteraldehyde.

A transformer mixing network is described which allows the calibration of broad-band masking for portable audiometers that lack a built-in mixing network. For many instruments the transformer network is preferable to the resistive network previously published.
