Belongs to the group of H. abrupta, H. pyrrhaspis, and H. dorsalis, and is distinguished by the white dorsal 
markings on the abdomen. Face and cheeks pale ochraceous, the face nearly perpendicular and scarcely 
prominent towards the oral margin; front cinereous, much narrowed behind (in 3); frontal band 
blackish, above the antenne ending in a more or less rufous callosity ; frontal bristles on both sides in a 
single row, but ending next the basal joints of the antenne in a double row; in the female a pair of 
more robust lateral bristles ; vibrissa accompanied by several shorter bristles ; beard yellow; pile of the 
occiput yellowish. Antenne not descending beneath the inferior part of the eyes; basal joints rufous ; 
second joint with several black bristles; third joint black (sometimes more or less rufous at the base), 
not broader than the second and nearly twice as long as it; arista thickened on the proximal half, 
Proboscis and palpi yellowish-rufous, the palpi with black bristles. Thorax yellowish-cinereous, with 
four distinct black stripes, which are interrupted at the transverse suture and do not reach the hind

neither stout nor long, even those of the middle tibie ; the spurs of the tibize and some of the other 
bristles yellow; foot-claws and pulvilli yellow, in the male elongate and surrounded by yellow hairs, the

Several males. A female from Sierra de las Aguas Escondidas, 9500 feet (H. H. 
Smith), seems to belong to the same species; it agrees in all the characters, except 
that the white markings on the abdomen are scarcely visible.
