2 MALACODERMATA. 
1. Lycus schonherri. (Tab. I. fig. 3, ¢ .) 
Lycus schénherri, Chevr. Col. Mex. Cent. ii. fase. vi. 147. 
Hab. Mexico (Hoge), Puebla (Sallé). 
Varies in size from 10 millim. to 18 millim.(¢). The body beneath is sometimes 
yellow ; but the legs are constantly black, except the trochanters. The figure is taken 
from a small male captured by Hége. In M. Sallé’s collection there were specimens 
as fully developed as the following species. 
2. Lycus carmelitus. (Tab. I. fig. 1, ¢.) 
Niger, femorum basi abdominisque apice flavis ; elytris prothoraceque ochraceis, hoc vitta mediana, illis apice 
oblique nigris. 
Mas elytris infra humeros rotundato-ampliatis. Long. 18 millim., lat. 15 millim. 
Femina oblonga, elytris infra humeros paululum dilatatis. Long 15 millim., lat. 6 millim. 
Hab. Mexico (Hoge, 3 ), Guanajuato (Sallé, 3 ¢ ). 
This species differs from L. schénherri in having the femora with the basal half yellow, 
and the black of the apex of the elytra not so wide, especially at the suture ; its inner 
margin is thus more oblique. In the male the seventh or penultimate segment is 
acutely lobed at the sides; the centre is bisinuate, angularly emarginate in the middle. 
The rostrum is as long as the thorax, with the antenne and rest of the head entirely 
black. The second joint of the antennz is so short as not to be easily seen, the third 
as long as the fourth and fifth united, compressed ; the remaining joints with their inner 
apical angles acute, the inner edge sinuate. ‘The prothorax is about, or nearly, as long 
as wide, prominent, and elevated into a small carina in front; a shallow, but widened, 
channel in the middle; the hinder angles are acute, but not much produced in either 
sex. The elytra show the usual four nervures distinct, the humeral or outer one most 
so; between them are indistinct indications of transverse reticulation and longitudinal 
cost, with intricate confluent punctures ; in repose the elytra overlap at the apex. 
The figure is taken from Hége’s male specimen. 
3. Lycus fernandezi. 
Lycus fernandezi, Dugés, La Naturaleza, iv. p. 175, t. 6. fig. 5 ¢, fig. 6 9. 
Hab. Mexico, Guanajuato (Sallé, 3 @ ). 
This species is undoubtedly very closely allied to the one preceding, and may possibly 
be only a local variation of it. The most constant differences are :—that the abdomen 
is wholly yellow; the femora are yellow, except at their apexes ; the prothorax is often 
entirely yellow, but in some specimens has a black vitta on the dorsal channel; the black 
of the apex of the elytra is more extended in the disk, and is emarginate where the 
humeral nervure cuts it; the subapical segment in the male is less acutely emarginate.
