rufous, the suture sometimes pale in apical half. Head behind the eyes in the 
male three-fourths as wide as the thorax. Antennae moderately strongly 
serrate in the male. Thorax a little transverse, sides feebly arcuate at middle, 
scarcely widened basally. Elytra minutely, sparsely punctulate, the decum- 
bent pubescence thin. Body beneath black, the margins and membranous 
median portions of the ventral segments pale as usual. Length 3 mm. 
California: San Diego (type); La Jolla; Laguna Beach. 
A specimen before me from La Jolla (near San Diego) is pre- 
cisely like some examples in the type series at Cambridge. The 
epistomal and ventral differences between this species and ab- 
dominalis recorded by LeConte and Horn, have no basis in fact 
and must have been due to inaccurate observation. 
Tanaops spinifer new species 
Black, elytra with greenish luster, epistoma and under side of the basal 
three joints of the antennae pale, as usual; thorax with sides more or less pale, 
typically and commonly with the hind angles alone paler, quite as often entirely 
black; elytra with the tips narrowly pale, the pale color sometimes extending 
forward along the suture. Head behind the eyes about three-fifths as wide as 
the thorax in the female, a little wider in the male. Antennae moderately 
serrate in the male, much shorter and feebly so in the female. Thorax slightly 
wider than long, sides rather straight, surface poUshed and subimpunctate. 
Elytra less shining, surface a little uneven, pale recumbent pubescence dis- 
tinct, punctuation sparse and fine. Body beneath black in the female, the 
abdomen pale in the male, with sides of first two ventrals blackish. Legs 
black, with trochanters and often base of front femora, pale. Front trochan- 
ters of male with an acute spine. Length 3 to 3.5 mm. 
Arizona; “S. Arizona, Aug.,” and “Oak Creek, 6000 ft. 
Aug.,” (Snow); Williams, (Fenyes). 
Two males and six females are before me. The type is a male 
labeled simply “Ariz. Aug.” It is I believe from Southern Ari- 
zona. At once distinguishable from all other species known to 
us by the spined front trochanters of the male. 
Tanaops terminalis new’ species 
Black, the elytra with greenish luster, strongly shining throughout, elytral 
tips narrowly red, abdomen black in both sexes. Head elongate, about three- 
fifths as wdde behind the eyes as the thorax in the female, a little wider in the 
male. Antennae moderately serrate in the male, not serrate in the female. 
Thorax slightly to scarcely wider than long, sUghtly but obviously widened 
behind, subimpunctate. Elytra sparsely, finely punctulate. Length 3.2 to 
3.5 mm. 
California: Lake Tahoe and Truckee, one male and four 
females.
