tip. There is scarcely a sign of pubescence — except for the few 
scattered very short, erect, black hairs, and from the fact that 
the. integuments are virtually impunctate, I judge this is the 
natural condition. The color of the elytra — half black, half yel- 
low — is quite different from any of our other species. 
Attalus semirubidus new specie.s 
Form moderate, upper surface shining, head and thorax red, the former with 
occiput black, elytra greenish black, apices narrowly red. Antennae feebly 
serrate in the male, joints two to six as wide as long, seven to ten becoming 
just perceptibly longer than wide. Head wider than long, but little narrower 
than the thorax, the latter transverse, rather strongly rounded at sides, ba.se 
broadly rounded, apex straighter, both head and thorax minutely, feebly, 
sparsely punctulate. Elytra rather coarsely punctate and with numerous 
rather long, semi-erect, black setae, the recumbent pubescence very fine, short 
and sparse. Body beneath red, the metasternum black; legs red, the front and 
middle tibiae and tarsi dusky, hind tibiae and tarsi blackish. Length 2.2 
mm. 
Alabama: Mobile (Loding). 
The type and only specimen at hand is a male. The elytra 
are scarcely dilated apically; the apical red margin extends for- 
ward very narrowly and diffusely along the sides to aliout the 
middle. This species differs from all previously described in its 
color arrangement, but may for the present be placed near mel- 
anopterus. 
Attalus demissus new species 
Moderately elongate, head and thorax distinctly shining, elytra less shining, 
vestiture much as usual, the erect, black setae of the elytra of moderate length. 
Head black, epistoma pale; thorax entirely black or with the reflexed margin 
around the hind angles pallescent ; elytra black, with the outer margins tip and 
suture (except at base) narrowly rufous. Body beneath and legs black. An- 
tennae (cf) more than half the length of the body, feebly serrate, the inter- 
mediate joints twice as long as wide; ( 9 ) shorter, joints one-half longer than 
wide. Head as long as, or slightly longer than wide, not much narrower than 
the thorax, the latter rather narrow, a little wider than long in the male, as 
long as wide in the female, sides parallel and feebly arcuate, surface minutely 
and sparsely punctate. Elytra a little wider behind in the male, more dilated 
apically in the female, surface feebly, finely punctate. Length 2.3 to 2.5 mm. 
Colorado; Glen wood Springs, July, (Fenyes). 
A single pair, of which the male is taken as the type. In the 
length of the head this species approaches oregonensis, and should 
probably stand between that species and those with broader
