Hab. Mexico, Tupataro, State of Guanajuato (Dugés!). 
Two examples, found on the walls of a dwelling-house, near the nests of an unde-

Horia, Fabricius, Mant. Ins. i. p. 164 (1787); Lacordaire, Gen. Col. v. p. 663. 
This genus is represented in the warmer regions of both hemispheres. A. maculata, 
Swed., is a common insect in Tropical South America, and extends northwards to 
Mexico ; according to Lansdown Guilding, it preys upon Xylocopa.

Two species are confounded by authors under the name of H. maculata (Swed.); their 
differences, however, have already been noticed by Lansdown Guilding®. Of the true 
H. maculata we have only received three examples from within our limits—a male 
from Morelia, a female from Chontales, and a male from Bugaba. The H. maculata 
of Dugés, and of Leconte and Horn, is no doubt referable to the species described 
below under the name of H. auriculata. H. apicalis, Perty, from Brazil, is apparently 
nothing but a variety of H. maculata (Swed.), from which it differs in having the base 
and apex only of the elytra black. A variety with the elytra entirely black occurs in 
Colombia. The head in H. maculata is flattened in front, or has a broad shallow 
median depression; the antenne are comparatively short in both sexes; the thorax is 
very broad, in some male specimens wider in front than at the base, strongly transverse,
