 in Guerrero (H. H. Smith). 



This species varies from 10 to 14 millim. in length. In all the specimens I have 

 seen the black on the mesonotum is much more extended than in Saussure's figure ; 

 in fact, in all of them the entire mesonotum is black. The second abdominal segment 

 varies in the amount of black on it, as does also the amount of black on the legs. 

 The third antennal joint is not much longer than the fourth. The keel on the basal 

 ventral segment is very distinct, and is rounded at the base, oblique at the apex, and 

 slightly incised in the middle. The hair on the head and thorax varies from very pale 

 fulvous to deep ochraceous.

Hab. Mexico, Venta de Zopilote in Guerrero 2800 feet (H. H. Smith). 



Head densely covered with white pubescence; subquadrate, rounded in front, 

 transverse behind ; the part behind the eyes almost double their width ; the antennal 

 tubercles and the base of the mandibles ferruginous. The antennae ferruginous ; the 

 scape curved, covered with long white hair ; the third joint twice the length of the 

 fourth. The thorax not much longer than the head, rounded in front, gradually 

 narrowed from the middle to the apex, the apex with an oblique slope, ferruginous ; 

 the apex of the mesonotum with a broad curved band of white pubescence, the front 

 part covered with very long black hair ; the pleurae covered with long white hair ; the 

 metapleurse reticulated. The abdomen as long as the head and thorax united ; dark 

 ferruginous above, the sides and the ventral surface much lighter in colour .; covered 

 with long black hair; the basal segment gradually dilated to the apex, covered with 

 long white hair; the second segment with a broad band of white pubescence, which, 

 in the middle, is triangularly extended backwards, reaching near to the base of the 

 segment ; the fourth and fifth segments covered densely with long white pubescence. 

 The pygidium coriaceous, fringed laterally with long fuscous hair. The basal ventral 

 segment coarsely punctured, the keel distinct, long, the base slightly, the apex 

 abruptly oblique ; the second ventral segment strongly punctured ; the segments 3-5 

 densely covered with white pubescence ; the sixth segment black. The legs ferru- 

 ginous, covered with long white hair ; the tibial spines and the calcaria black.
