PACHYBEACHYS. V3 



punctured striae, mostly running in pairs — the first pair enclosing a smooth round space near the suture, 

 connected, but abbreviated, at some distance from the apex, the second pair also connected at its end 

 but much shorter than the first pair, the following rows indicated only by a few punctures below the 

 shoulder, some others at the middle, but placed transversely, and a short curved row near the apex ; the 

 shoulder and an indistinct mark at the middle near the lateral margin brown ; underside of the same 

 colour ; the sides of the abdomen and the base and apex of the legs white. 



Ilab. Guatemala, Panzos (Champion). 



Of this species a single female only has as yet been captured. There is no doubt 

 that it approaches in its pattern P. contortus, Baly, and also P. clathratus, Suffr. ; it 

 is, however, larger, the thorax is more rounded, and the sculpture of the elytra, 

 although like that of the above-named species, runs differently and is shaped otherwise.

Pachybrachys melanostictus, Suffr. Monogr. vii. p. 191 \ 



Hab. North America, California K— Mexico (Baly); Guatemala, San Geronimo 

 (Champion). 



Only a single specimen has as yet been collected by Mr. Champion, which agrees very 

 nearly with a typical specimen named by Suffrian in Mr. Baly's collection. The elytra 

 in this species have a black spot at the shoulder, and another below the base near the 

 suture, also a raised smooth roundish yellow spot at the middle close to the suture, of 

 which Suffrian makes no mention ; the outer parts of the elytra are rather regularly 

 but narrowly costate, the costse uniting at a little distance from the apex. 



26. Pachybrachys reticulatus. (Tab. IV. fig. 10.)

 Pachybrachys jucundus, Dejean, Cat. 3rd ed. p. 445. 



Hab. Mexico (Baly).— Venezuela 1 ; Colombia 1 ; Bolivia 1 . 



Although this species has a wide distribution, it has not yet been recorded from 

 Central America. A specimen, however, is contained in Mr. Baly's collection, which 

 we now figure on our Plate. 



Fam. CHLAMYDID-E. 



Chlamydia, Laeordaire, Monogr. in Mem. Soc. Liege, v. ( 1 848) . 



These curiously shaped and remarkable insects, of which more than 200 species 

 have already been described, have their metropolis in the hotter regions of the New 

 World ; very few have been as yet described from the Old World, although Africa 

 and the Malayan Archipelago are not entirely devoid of species. Central America 

 now furnishes us with more than forty species, some of which extend as far south
