CHLAMYS. 87 



close to the lateral margin, but only at its first two thirds ; all the interstices distinctly transversely 

 wrinkled posteriorly or reticulate ; pygidium rugose and longitudinally striate at the base, with a distinct 

 elevated central ridge ; underside deeply punctate, of the same dark indigo-blue as the elytra, with the 

 exception of the thorax and the legs, which are fulvous. 



Eab. Mexico, Juquila (Salle). 



Of this interesting species only one specimen is before me. It belongs, without 

 doubt, to Lacordaire's group containing C. granulicollis, C. pohlii, and others, but is 

 sufficiently distinguished by its colour. 



35. Chlamys maculicollis. (Tab. V. fig. 9.) 



Elongate, subcylindrical, light yellowish brown, closely covered with black punctures ; thorax with a black spot 

 near the base ; elytra with five more or less distinct longitudinal costse. 



Length 1J line. « 



Head flat, light yellowish, with some more or less closely placed brown punctures ; antennse robust, transverse 

 from the fourth joint, flavous, the three or four apical joints black; thorax twice as broad as long when 

 seen from above, with a high elevation, the latter truncate at the top and divided by a longitudinal 

 groove, the edges of which are acute ; surface slightly rugose, more or less closely covered with black 

 punctures, whicb near the base congregate in such numbers as to form a distinct black patch ; scuteUum 

 impunctate ; elytra of the same colour as the thorax, closely covered with black punctures and the usual 

 more or less distinct longitudinal lines as in G. stictica and others; underside and legs light fulvous, the 

 breast sometimes black, also closely covered with dark punctures ; claws very distinct and rather long, 

 apperidiculate. 



Eab. Guatemala, near the city, Capetillo, Duenas (Champion). 



The elytra in this species do not differ from many belonging to Lacordaire's sixteenth 

 group ; the general light colour, dark thoracic basal spot, and the different shape of the 

 latter's callosity, which is not rounded above but truncate, will distinguish the present 

 species, of which eight specimens are before me, which show but slight variation, and 

 of which one from the neighbourhood of the city of Guatemala is figured here.

The very elongate shape of this species, which surpasses in that respect C. elongata, 

 will help to distinguish it.
