HOLONOTUS.—THAUMASUS. 13 
genera, found only in the West Indies. Three species have been recorded, all of which 
are rare. 
1. Holonotus nigrozneus. (Tab. II. fig. 11.) 
Holonotus nigroeneus, Bates, Trans. Ent. Soc. 1869, p. 57; id. 1872, p. 169. 
Hab. Nicaraaua (Belt, Janson). 
A variety of this insect occurs with bright red femora and tibie. 
2. Holonotus levithorax. 
Solenoptera levithorar, White, Cat. Long. Col. B. M.i. p. 54. 
Hab. Guatemaa (Deby). 
3. Holonotus latithorax. 
Holonotus latithorax, Thoms. Class. Long. p. 305. 
Hab. Mexico. 
Fam, CERAMBYCID. 
Subfam. CHRAMBYCIN. 
This subfamily is proposed here provisionally to include all Cerambycids with coarsely- 
faceted eyes. It comprehends Lacordaire’s “ Cérambycides aberrants” as well as 
Section A of his “‘ Cérambycides vrais sylvains.” Thus conceived it embraces a prodi- 
gious number and diversity of generic forms, which no doubt contain the elements of 
several subfamilies equivalent to the “ Prionine.” A thorough revision, founded on all 
the material contained in the large public and private collections of Europe, would be 
required to settle the limits of the larger groups of genera in question. 
THAUMASUS. 
Thaumasus, Reiche, Ann. Soc. Ent. Fr. 1853, p. 419. 
1. Thaumasus gigas. 
Ips gigas, Oliv. Journ. Nat. Hist. i. p. 267, t. 14. f. 6 (1792). 
Thaumasus gigas, Reiche, Ann. Soc. Ent. Fr. 1853, p. 422, t. 18. iv. f.1, la. 
Hab. Costa Rica.—CoLoMBiA. 
Notwithstanding the very different facies, the shortness of the antenne, and other 
points of structure, I believe the real affinities of this remarkable insect lie in the direc- 
tion of Torneutes and Diploschema. The following genus forms, to some extent, a con- 
necting link between these genera.
