560 Coleopterological Notices^ VII. 



eyes moderate in size, convex, at more than their own length from the base, the 

 tempora behind them much less prominent, parallel and scarcely arcuate to 

 the truncate base, the latter very feebly and minutely impressed at the base of 

 the occiput ; fovea3 slightly behind the middle, large, deep and separated by 3^ 

 the total width ; antennse partially mipsiiDg in the type. Prothorax slightly 

 ■wider than long, widest and somewhat prominently rounded before the mid- 

 dle, the sides thence convergent and not at all s nuate to the base ; fovese large 

 and deep, connected by a very coarse and deep transverse sulcus, which is an- 

 gulfirly dilated posteriorly at the middle ; median line finely and feebly im- 

 pressed. Elytra not quite as long as wide, % longer and nearly % wider than 

 the prothorax ; humeral plica rather prominent ; sides nearly parallel, broadly 

 and evenly arcuate throughout ; disk broadly convex, the sutural stria deep 

 and straight ; discal stria distinct, extending well behind the middle ; basal 

 fovete two in number, the intra-humeial depression large. Abdomen decidedly 

 narrower and somewhat longer than the elytra, parallel and very feebly arcuate 

 at the sides ; segments equal in length toward base, convex, minutely and 

 sparsely punctulate basally, the basal carinfe rather short, straight, parallel 

 and separated by fully % of the discal width ; secondtral ven segment nearly 

 as long as the next two combined. Length 1.6 mm. ; width 0.6 mm. 



California (Siskiyou Co.). 



This very isolated species can be distinguished at once from 

 any other, with bifoveate ely tral base, by its large size, very small 

 head, finely impressed median line of the pronotum, finely rugu- 

 lose el^'tra with an unusually long discal stria and by many other 

 characters. It is represented by a single female in rather poor 

 condition. 



Trimiopsis Reit. — The type of this genus is T. clamceps Reit.,, 

 from" Colombia (Deutsch Ent. Zeits., XXYI, 1882, p. 150), an in- 

 sect of rather large size for the present group, and having a re- 

 markable cephalic development. Most of the minute species, 

 subsequently placed here b^^ Reitter, belong to other genera • 

 specularis, for instance, is assignable to Melba and eggersi, which 

 I erroneously^ regarded as typical of Trimiopsis (Col. Not. V, p. 

 462), must form the type of another genus named " Zolium " in the 

 table. Some of the characters given in the table in defining 

 Trimiopsis are assumed, as no allusion to them is made in the 

 original desci'iption, such as the presence of a post-humeral fovea, 

 isolated lateral pronotal fovese and elongate discal stria of the 

 elytra, for example. There seems to be a tendenc3Mnthe large ter- 

 minal joint of the antennae to split at apex along an axial plane 

 in many of these minute trimioid forms, and the notice which 

 I formerly drew to this character in specularis (1. c.) is of no 

 significance from a generic viewpoint.
