Dichrooscytus speciosus, new species 



Allied to suspectus but more polished. Black; disk of head, pronotum 

 and elytra deep rich wine-red; scutellum, base of cuneus and legs white; 

 antennae soiled white. Length nearly 6 mm. 



Head broader and shorter than in suspectus, vertex strongly impressed 

 before the basal margin and more broadly on either side; middle of 

 vertex quite strongly swollen and polished, without the transverse striae 

 seen in the allied species; basal carinae prominent across the whole width. 

 Pronotum narrower anteriorly, meeting the vertex near the inner angle 

 of the eye; surface more strongly punctured, callosities smaller and 

 highly polished; median line obscure but evident. Scutellum prominent, 

 narrower than in suspectus, polished, a little transversely shagreened 

 toward the base. Elytra polished, very obscurely punctured and 

 shagreened, almost parallel, costa straight basally. 



Color black, highly polished; base of vertex obscurely reddish. Pro- 

 notum deep wine-red with anterior and posterior margins black. Scutellum 

 ivory-white, becoming black on anterior lobe beneath base of pronotum. 

 Elytra dark wine-red; broad margins of clavus about scutellum and the 

 ajiex of corium black; cuneus black, the basal half ivory-white omitting the 

 slender costal margin. Membrane deep fuscous, iridescent, the nervures 

 concolorous. Legs including coxae white, coxae and trochanters some- 

 times tinged with greenish; apex of the tibiae and the tarsi slightly 

 infuscated, last tarsal joint becoming black at apex. Antennae soiled 

 white, a little more infuscated toward the apex. Tergum and apex of 

 abdomen more or less sanguinous. 



Described from nnmerous examples beaten from juniper trees 

 during July, mostly on the south slope of ]\Iount Tallac. The 

 first mature examples were taken near the Lodge on July 5 but 

 the adults did not become abundant until after the middle of the 

 month. This is one of the most beautifully colored capsids known 

 to me. The immature have paler colors but the pattern is distinct 

 and characteristic. 



Dichroosci/tus suspectus Rent. Common on juniper trees 

 during July. These individuals are more uniformly colored with 

 rufous than those from Colorado determined for me by Dr. 

 Eeuter. but they can hardly be distinct. 



Dichrooscytus irroratus Van D. Common on juniper and 

 cedar trees everywhere between 6000 and 8000 feet. In most of 

 these examples the elytra are of an almost uniform pinkish color 

 with a deeper tint on the cuneus, and marked with a fuscous vitta 

 on the apex of the corium ; an oblique vitta on their middle and 

 the apex of the membranal areoles are also fuscous.
