Attalus atripennis new sj)ecies 
Form sliort and broad, moderately shining, subimpunctate and subglabrous, 
the pubeseence very sparse, fine short and subereet. Head, thorax, antennae 
and legs rufo-testaceous, the outer joints of the antennae dusky, coxae and 
base of hind thighs blackish; elytra, metasternum and abdomen, black. An- 
tennae ( 9 ) scarcely passing the base of the thorax, not serrate, joints a little 
longer than wide. Head wider than long, thorax strongly transverse, about 
one-half wider than long, elytra moderately widened apically. Length 2.o 
mm. 
Arizona: Santa Rita Mountains, (Snow). 
The type and only specimen before me is a female. It is 
evidently allied to melanopterus, but the latter has the abdomen 
pale, the thorax less strongly transvferse and the antennae a 
little stouter. In melanopterus the hind femora are pale at base 
and blackish apically. 
Attains glabrellus new species 
Form rather stout, distinctly shining throughout, nearly glabrous and .sub- 
impunctate. Black, thorax typically with a rufous spot at the hind angles, 
varying to entirely black, or with the sides broadly rufous. Head broad, epis- 
tomal margin pale. Antennae ( cf ) scarcely half as long as the body, scarcely 
serrate, basal joints more or less pale, intermediate joints a little longer than 
wide. Thorax transverse, subtruncate in front, broadly rounded behind. 
Elytra gradually wider behind in the male, more strongly dilated posteriorly 
in the female, surface minutely subrugulose. Legs black, the front tibiae and 
tarsi more or less piceo-testaceous. Length 1.75 to 2.25 mm. 
California: Pomona (type cf), Pasatlena, Claremont, Azusa, 
San Diego, Mount Wilson, San Bernardino Mountains, Kern 
County, Santa Clara County, Marin County. 
An abundant species in Southern California. A form taken 
by the writer at Williams, Arizona, is very similar, but in this the 
pubescence and punctuation are not so nearly obsolete and the 
legs differ a little in color; quite likely no more than a geographical 
race. This species is quite closely allied to lecontei Champion 
(basalts LeConte), but I feel confident they are not identical. In 
the type of the latter the thorax is finely but distinctly, numer- 
ously punctate, the base margined with yellow, and the legs, ex- 
cept the hind femora in part, are pale; it was described from the 
desert region along the Colorado River. 
Attalus rusticus new species 
Moderately elongate, a little wider behind, browmish piceous to dull black, 
lateral and basal margins of thorax rufous. Head feebly shining, thorax more
