thorax, second and third joints together longer than fourth. Prothorax 

 about as long as wide; sides moderately arcuate, gradually narrowing 

 towards apex, hind angles slightly divergent with a moderately long, acute 

 carina; surface rather coarsely and not very closely punctate, pubescence 

 rather short and sparse. Scutellum conically raised in front. Elytra 

 nearly twice as long as prothorax ; sides scarcely arcuately to a little be- 

 yond middle thence rather more arcuately to narrowing towards the con- 

 jointly rounded apices; strise distinctly impressed and with close, moderate 

 coarse punctures which are coarser towards the sides ; intervals feebly 

 convex, sparsely and rather finely punctate; surface sparsely clothed with 

 short, gray hairs. Prosternum rather coarsely but not densely punctate, 

 the punctures finer near apex ; side pieces more densely punctate. Abdom- 

 inal segment's one to four, not densely punctate, the punctures coarser at 

 sides than at middle, last segment finely and densely punctate towards 

 apex. Fourth tarsal joint slightly excavated above. Length 7 (type) -5.5 

 mm. Brownsville, Texas. 



• This species differs from all our known N. Am. species in the 

 conical raised scutellum. Small specimens resemble aniabilis in 

 form more than dorsalis but, besides the different form of scutel- 

 lum, haye longer carinse of the hind angles of prothorax and 

 coarser elytral strise. It is evidently closely allied to the Mexican 

 circumscriptus Champ, with which the description and figure 

 agrees -very well, except that the interstices are said to be roughly 

 punctured in that species, which are in scutellatus rather finely 

 punctured. 



Megapenthes nigriceps Schaef. — In the material collected in 

 Brownsville, Texas, by the late Ottomar Dietz I found a female 

 of this species, which I described from a single male collected by 

 myself. ^ This female has the head not piceous or black but dark 

 ferruginous behind and paler in front, otherwise it does not differ 

 from the male except, as usual, in stouter form, shorter anten- 

 nae, etc. 



Betarmon californicus n. sp. Antennae, head, legs and underside, except 

 side pieces of prosternum, base of elytra and a rather broad, but indefinite 

 sutural stripe black or piceous; pronotum and side pieces of prosternum 

 yellowish ferruginous and sides of elytra pale yellowish brown. Surface 

 sparsely pubescent with short yellowish hairs. Head rather coarsely and 

 densely punctate, front distinctly margined and arcuate. Prothorax slightly 

 longer than wide ; sides gradually converging from base of hind angles to 

 a little above middle, then arcuately narrowing to apex ; hind angles rather 

 feebly diverging and not carinate ; surface closely punctate with moder- 

 ately coarse punctures. Elytra a little more than twice as long as pro-
