of it. The larger form with longer and more curved apical lobes to the pronotum is 
confined to Tropical South America. D. lunatus is not uncommon in the “tierra 
caliente” of Central America, occurring on both the Atlantic and Pacific slopes. A 
male of the normal Central-American form, from Bugaba, is figured.

An abundant insect in Central America, especially on the Atlantic slope, extending 
from the “tierra caliente” to an elevation of about 5000 feet in the mountains. 
A male from El Reposo is figured. 
8. Dysodius brevipes. (Tab. VI. fig. 13, 3.) 
Dysodius brevipes, Bergr. Wien. ent. Zeit. xvii. p. 26 (¢) (Jan. 1898)". 
Broad ovate, ferrugineo-fuscous, the connexivum more or less mottled with fuscous; the upper surface rather 
coarsely granulate, and here and there coated with a pale luteous incrustation. Head longer than broad, 
the granules very coarse, becoming spiculiform at the sides and base; the spiniform antenniferous 
processes long, acute, and divergent; the apical process long and stout, bifid at the tip, armed with 
obliquely projecting spines on each side; the post-ocular portions broad, semi-lunate, curving outwards and 
forwards to beyond the eyes, terminating in a rather long spine in the male; antenne moderately long, 
joint 1 stout, about one-third longer than the apical process, 2 considerably shorter than 1, 3 a good deal 
longer than 2, 4 one-half the length of 3. Pronotum with the apical lobes broad, moderately long, 
slightly curved, rounded laterally and at the tip; the posterior portion separated from the anterior 
portion by a deep groove, rounded at the sides behind, becoming subparallel forwards; the lateral and 
apical margins (the lobes included) coarsely crenate. Abdomen broad, rounded and crenulate at the sides 
in both sexes; the genital lobes broad in the female, narrow in the male; the ventral surface somewhat 
closely, rather finely punctate, the raised central portion of the first segment strongly transverse. Legs 
short, the hind femora extending very little beyond the abdomen. . 
Length 13-134; breadth of the anterior part of the pronotum 33-4, of the abdomen 7 millim. (¢ 9.) 
Hab. Mexico, Presidio de Mazatlan (Forrer: 2), Venta de Peregrino in Guerrero 
(H. H. Smith: 3), Cuernavaca in Morelos (Mus. Vind. Ces.: ¢ *). 
Allied to D. crenulatus, Stal, but differing from it in having the pronotum subparallel 
at the sides behind the apical lobes, these latter being broader and less divergent than 
in that species; the head is also more dilated at the sides behind the eyes, and the 
legs are shorter. The longer antenne, the longer, spiculiferous process of the head, 
and the less divergent apical lobes of the pronotum separate it from D. ampliventris.
