Coleopterological Notices, V. 36T 



narrower than the prothorax, fully as long as wide ; eyes at fully one-half 

 more than their own length from the base ; clypeus rather prolonged in front 

 of the antennae, truncate ; antennae nearly one-half as long as the body, dis- 

 tinctly incrassate, second and third joints elongate, subequal, fourth to tenth 

 very evenly, gradually increasing in width, the latter fully twice as wide as 

 long, eleventh conoidal, longer than the preceding two. Prothorax rather 

 large, strongly and evenly convex, but slightly wider than long, widest at 

 apical third, the sides thence distinctly convergent and feebly sinuate to the 

 base, the latter transverse and slightly narrower than the apex ; basal angles 

 obtuse but not at all blunt ; apical deflexed but not at all rounded ; hypomera 

 continuous to the apex. Elytra at apex as wide as the prothorax, gradually, 

 feebly narrowed toward base, the two bases equal; suture just perceptibly 

 shorter than the pronotutn ; sides feebly arcuate ; apex transverse and slightly 

 trisinuate ; disk rather convex, not impressed on the suture, the latter finely 

 beaded. Abdomen as wide as the elytra, as long as the anterior parts, parallel, 

 the sides nearly straight ; border moderate ; first three segments strongly im- 

 pressed and more coarsely punctate at base ; fourth scarcely at all impressed ; 

 fifth distinctly shorter than the fourth. Legs moderate ; posterior tarsi slender, 

 nearly two-thirds as long as the tibiae, the first joint slightly but distinctly 

 longer than the second. Length 2.0 mm. ; width 0.5 mm. 



California. 



This species is allied closely to reitteri Epp., but the latter has 

 the first four segments equally impressed at base and the fifth fully 

 as long as the fourth. In frontalis the labial palpi have the first 

 joint shorter than the second, the third nearly as long as the first 

 two, the metaparapleurae very wide, with the inner margin rapidly 

 divergent from the elytra, the epimera large, occupying nearly the 

 entire width behind and disappearing under the elytra near basal 

 third. The mesosternal process is long, acute, extending two-thirds 

 the length of the very narrowly separated coxae, the apex free, the 

 metasternal process short, subangulate, not attaining the meso- 

 sternal, the acetabula rather shallow behind but limited every- 

 where by a fine beaded edge, except along the very short inter- 

 sternal isthmus. 



BRYOBIOTA n. gen. 



Body parallel and linear, somewhat thick and convex. Head 

 fully as wide as the prothorax and as long as wide, with the sides 

 parallel ; basal angles right but rounded ; base transverse ; neck 

 scarcely one-half as wide as the head ; labrum twice as wide as 

 long, truncate; eyes small, anterior; infralateral carina completely 

 obsolete. Antennae long, the second joint longer than the third.
