CRYPTORHOPALUM. 667 
39. Cryptorhopalum fraternum, sp. n. 
Suboblongum, leviter convexum, nigrum, elytris vel rufis vel fusco-nigris, subtiliter pubescens, antennis 
pedibusque testaceis; maris antennarum clava magna, ovali, articulo ultimo perparvo. 
Long. 3 millim. 
flab. Mexico, Omilteme, Xucumanatlan, and Chilpancingo in Guerrero, 4600 to 
8000 feet (H. H. Smith). 
Very similar to C. vestitum, but rather narrower, with the sides of the thorax less 
flattened out, the pubescence just a little shorter, and the club of the male antenna 
strongly different; this latter forms a moderately narrow, oval piece, having the 
terminal joint minute and closely connected with the main joint. The club in the 
female is of similar shape, and the terminal joint is about as large as it is in the male, 
but the preceding joint is a good deal smaller. The eyes of the male are somewhat 
larger than those of the female. Eleven specimens. 
The female of this insect having the sides of the thorax almost simple, it is very 
liable to be mistaken for a male belonging to the other section, especially as the 
antenna is very like that of the male of several other species. ‘The variation in colour, 
from nearly black to pale red or testaceous, is partly due to maturity or the opposite, 
but probably only partly so; the colour of the legs varies like that of the body. 
40. Cryptorhopalum vicinum, sp. n. 
Suboblongum, leviter convexum, nigrum, elytris vel rufis vel fusco-nigris, subtiliter pubescens, antennis 
pedibusque testaceis ; maris antennarum clava oblongo-ovali, articulo ultimo sat parvo. 
Long. 23-3} millim. 
Hab. Muxico, Jalapa, Cerro de Plumas (Hége). 
This species varies in colour like C. fraternum, and is, so far as I can find, only to 
be distinguished by the more slender antenne, and those of the male having the 
terminal joint larger in comparison with the preceding one. When the sexes of 
the two are compared, their distinction is not difficult. In the female of C. vicinum 
the club is, in proportion to its width, considerably longer than usual. Hight 
specimens. 
41. Cryptorhopalum pedestre, sp. n. (Tab. XIX. figg. 25, 9; 254, ¢ 
antenna. ) 
Suboblongum, convexum, fusco-nigrum, supra ferrugineum, griseo-pubescens, pubescentia in elytris longi- 
tudinaliter vittata ; antennis pedibusque rufis, illarum clava maxime elongata. 
Long. 33-4 millim. 
Hab. Guatemaua, Cerro Zunil 4000 to 5000 feet (Champion). 
One of the most distinct members of the genus, the antennal club in the female 
being elongate (more so, indeed, than in the males of many species), while in the male 
it is very elongate, with the terminal joint longer than broad, though much shorter
