Ipsimorpha striatopunctata, Reitter, Verh. Ver. Brinn, xii. 1, p. 165 - 
Hab. Mexico !. 
2. Ipsimorpha ruficapilla.

Hab. Mexico (Bilimek '). 
Fam. TROGOSITID *. 
The catalogue of this family recently published by M. Léveillé (Ann. Soc. Ent. Fr. 
1888, pp. 431-448) includes 335 species. About 100 species are here recorded from 
our region, and as between sixty and seventy appear to be new, the described repre- 
sentatives of the family will now reach about 400. 
No extensive or well-named collection of Trogositide exists in this country ; I should, 
therefore, have experienced some difficulty in determining the species previously known 
had it not been for the kindness of M. Léveillé of Paris, who examined for me a 
nearly complete series of the species hereafter enumerated. I am glad to take this 
opportunity of thanking him for his assistance. 
Subfam. VEMOSOMATIN A. 
NEMOSOMA. 
Nemozoma, Latreille, Nouv. Dict. d’Hist. Nat. 1st ed. xxiv., Tab. Meth. p. 157 (1804); Gen. Crust. 
et Ins. ii. p. 12. 
Nemosoma, Latreille, Gen. Crust. et Ins. iv. p. 381 (1809). 
This genus consists of two or three European species, to which Reitter has added 
one from Colombia, founded, I believe, on a single example. The Colombian insect 
differs from the European type, according to Reitter, in possessing 11-jointed antenne. 
In this respect the species I now describe from our region agrees with the Colombian 
one, and the two may therefore prove to be really congeneric. ‘There is little doubt 
they will have to form a genus distinct from Memosoma, as, besides the difference in 
the number of joints of the antenne, the trophi are more largely developed in the 
Guatemalan NV. signatum. 
1. Nemosoma signatum, sp.n. (Tab. XII. fig. 22.) 
Elongatum, angustum, nigrum, supra eneum, elytris signaturis quatuor testaceis, antennis pedibusque rufis. 
Long. 43-54 millim. . 
Hab. Guatemata, Quiche Mountains, 7000 to 9000 feet, Totonicapam 8500 to 
10,500 feet (Champion).
