Somewhat similar in general aspect to the preceding, but with 
many points of difference, notably the non-serrate antennae, 
dilated elytra and ventral foveae. 
Attains futilis new species 
Black with faint greenish luster, moderately shining, sparsely setose, and 
with rather plentiful, fine, pale pubescence. The epistoma, margin of thorax 
very narrowly at the hind angles, and the basal three joints of the antennae in 
part, are pale. Antennae (cf) scarcely serrate, attaining the elytral humeri, 
joints three to eleven evidently longer than wide. Head moderately broad 
but evidently narrower than the thorax, the latter transversely oval, elytra 
gradually, moderately dilated apically, upper surface throughout very finely, 
but distinctly and numerously punctate. Body beneath black, the last three 
ventral segments narrowly pale at sides in type, but not evidently so in other 
examples. Legs black. Length 1.6 to 2 mm. 
New Mexico: Pecos, June to July, (Cockerell), three males, 
two females. 
In one male the basal six joints of the antennae are pale be- 
neath, as are the front and middle legs in great part. This small 
and inconspicuous species would fall near morulus in Horn’s 
table; the latter is, however, much larger, less pubescent, less 
evidently punctate and with longer, stouter antennae. 
Attains grisellus new species 
Very similar to the preceding, differing as follows. Pale pubescence more 
abundant, giving a grayish aspect, the punctuation also a little stronger and 
closer, the surface in consequence less shining. The pale spot at the hind 
angles of the thorax is larger, and the elytra have the appearance of being 
finely, sparsely subtuberculate, not at all so in futilis. Length 2 to 2.4 mm. 
New Mexico: Alamogordo, April and May, (Viereck and 
Rehn). Type no. 8123, Acad. Nat. Sci. Phila. 
It is possible that this species is no more than a variety or race 
of the preceding; the nine examples before me are, however, 
quite constant in showing the differences mentioned. The type, 
a male, is returned to the Academy of Nat. Sciences, Philadelphia; 
paratypes are in my own collection. 
Attalus rostratus Horn 
The unique type is a female, the head very elongate, the elytra 
opaque and subrugose, perhaps abnormally so. It is more than 
likely that the male will show this to be a Tanaops, in which 
case it may prove to be the angusticeps of the present paper, and 
this, as already stated, may really be the apicalis of ^Moschulsky.
