MIMOLOCHUS. 
Mimolochus, Thomson, Physis, ii. p. 99. 
An exclusively Mexican genus, perfectly distinct from the preceding, and more 
- nearly allied to genera of the Old World. One species only is yet known :— 
1. Mimolochus hepfneri. 
Mimolochus Hefneri, Thomson, Syst. Céramb. p. 554; Physis, ii. p. 100.

| MONOHAMMUS. 
Monohammus, Serville, Ann. Soc. Ent. Fr. 1835, p. 91 (Monochamus, err. typ.). 
Deducting the numerous species belonging to the genus Dihammus, Thomson (which 
Lacordaire included in Monohammus), and the species of Tropical Africa (which are 
generically distinct by the narrowness of the cicatrice of the antennal scape), the genus 
Monohammus is confined to such species of the heterogeneous assemblage compre- 
hended in recent works as are closely allied to the European and North-American 
members enumerated by Serville and Lacordaire. To these naturally belong also a 
few from Eastern Asia and India. About twenty species of true Monohammus have 
been described. The following is the first yet recorded from America south of the 
United States :— 
1. Monohammus rubigineus. 
M. clamatori (Leconte) affinis. Ferrugineo-fuscus, subtus ferrugineo-lanuginosus; vertice vittis duabus 
approximatis et thorace vittis abbreviatis quatuor fulvis, elytris maculis numerosis ex parte confluentibus 
tomentosis fulvo-ferrugineis; thorace latius cylindrico, transversim ruguloso; elytris passim aspere 
punctatis (juxta suturam vix rugulosis), apice ad suturam paullo productis ; antennis rufescenti-fuscis. 
Long. 83-94 lin. § Q. 
Hab. Mzxico (Sallé). 
Two examples in M. Sallé’s collection. The species is very closely allied to the 
Californian JL. clamator, having similar spots of close rust-coloured tomentum scattered 
over the elytra. It is, however, a much broader insect, less wrinkled on the elytra, 
and has the under surface of the body densely clothed with long woolly hairs. 
Group APOMECYNINI. 
The Old-World genus Apomecyna forms an easily-recognized and distinct type in the 
Lamiade, uniting a cylindroidal form of body and unarmed thorax with subparallel 
tarsal claws, sinuate external edge of the tibi, and especially a short antennal scape, 
suddenly thickened on the outer side from the base, and entire at the apex. The more
