It is less hairy than the species of Pristoscelis usually are, and the elytra are very 
obsoletely sulcate towards their apices. 
PRISTOSCELIS (p. 123). 
Pristoscelis nigrozneus (p. 124). 
To the Mexican locality given, add:—Monclova in Coahuila (Dr. Palmer), Puebla 
(Sallé). . 
This insect has of course nothing to do with Dasytes nigroeneus, Kust. (Kafer Eur.), 
an Italian species. It is perhaps unfortunate that I overlooked the fact of there being 
a European species of Dasytes with this name, but as I retain the genus Pristoscelis I 
do not think it necessary to change it. 
1 (a). Pristoscelis zneipennis. 
Niger; capite prothoraceque crebre et subrugose, elytris parcius profunde, punctatis, his eneis; dense nigro- 
pilosellus; antennis quam caput et prothorax brevioribus. Long. 5 millim. 
Hab. Mexico, Ciudad in Durango 8100 feet (forrer). 
Rather larger than the largest specimens of P. nigrowneus, and chiefly distinguished 
from that species by the closer punctuation of the thorax and the sparser and deeper 
punctuation of the elytra. In this respect, as well as by the brassy colour of the 
elytra, it reminds one at once of the European genus Haplocnemus. ‘The thorax is 
also inclined to a brassy tint, but the head is black and dull, the antenne wholly black 
and rather hairy, and the legs black. | 
Three specimens. 
1(s). Pristoscelis rufipennis. 
Dasytes rufipennis, Leconte, Proc. Ac. Phil. 1858, p. 71"; ibid. 1866, p. 356°. 
Hab. Norru America, Arizona?.—Mexico, Sonora!, Puebla (Sai/é). 
“ Distinct by the large size (six millim.), and by the red elytra. Punctuation distinct 
but close, occasionally confluent, and of the kind termed ‘stellate ;’ tibiee reddish.” 
Two specimens from Sallé’s collection. 
1 (c). Pristoscelis suturalis. 
Dasytes suturalis, Leconte, Proc. Ac. Phil. vi. p. 169 (1853) *. 
Pristoscelis suturalis, Lec. loc. cit. 1866, p. 354”. 
Hab. Norra America, San Diego in California !?.—Mexico, Northern Sonora (Mor- 
vison). 
Elytra clothed with fine ashy rather erect pubescence at the sides and suture; 
legs red. 
Taken by the late Mr. Morrison in some numbers on the Mexican border.
