NORTH AMERICAN MALACHIIDAE 
evidently so, elytra opaque; fine, pale, recumbent pubescence quite evident, 
mostly transversely directed on the disk, erect setae rather short but distinct 
in profile. Head nearly as wide as the prothorax, black, epistoma more or less 
pale. Antennae in the male narrowly serrate, joints three to ten one-third to 
three-fourths longer than wide; in the female scarcely serrate, joints three to 
ten nearly equal in length and about one-half longer than wide. Thorax trans- 
verse, broadly oval, with the usual scattered minute punctures. Elytra at base 
slightly wider than the thorax, fully twice as long as wide, surface finely, feebly, 
rather closely punctulate and feebly subrugulose. Body beneath blackish, 
legs brownish piceous to black, femora indefinitely paler at base in some ex- 
amples. Last dorsal segment of abdomen with a shallow notch at apex in 
both sexes; fifth ventral of male with a smooth, transversely oval fovea each 
side of the middle and near its posterior margin. Length 2. .5 to 3 mm. 
Southern Arizona. The type — a male, and one female were 
taken at Pearce, Cochise County, May 19, by Mr. V. L. Clem- 
ence. 
With these I place, without hesitation, two female examples 
from the Dragoon Mountains and Santa Rita Mountains, also 
taken by Mr. Clemence. In the latter the thorax is entirely 
black, except for a small rufous spot at the hind angles, while in 
the Dragoon Mountains one it is yellow with a black discal spot. 
The notched apex of the last dorsal segment is an unusual char- 
acter, still more pronounced in the following species, but not else- 
where noticed by me. The ventral foveae in this and the fol- 
lowing species suggest a relationship with Tanaops, but the nar- 
row elongate lobe of the second joint of the anterior male tarsi 
is typical of Attains. 
Attalus foveiventris new species 
Black, elytra with greenish luster, thorax red with black discal space of vari- 
able size. Head and thorax distinctly shining, elytra only moderately so, 
vestiture as in the preceding, the black setae rather more conspicuous. Head 
nearly as wide as the thorax, black, epistoma in great part pale. Antennae 
black, not serrate, joints three to ten subparallel and nearly twice as long as 
wide in the male, in the female smaller and with the joints less elongate, but 
evidently longer than wide. Thorax transverse, sides rather strongly rounded, 
punctulate and pubescent as usual. Elytra slightly wider at base than the 
thorax, strongly dilated apically in both sexes, punctuation and vestiture nearly 
as in the preceding species. Body beneath black, the last three ventrals red 
in the male. Legs entirely black. Last dorsal segment of abdomen distinctly 
notched at tip in both sexes, rather deeply so in the male. Male with fourth 
and fifth ventral segments foveate each side of the middle. Length, 2.5 mm.
