130 PHTTOPHAGA. 



short oblique raised ridge below the shoulder. It is true that I have before me, from 

 the same locality, specimens of the same colour ; but in none of them is the punctuation 

 of the elytra so strongly impressed, and that of the thorax so distinct and close, as in 

 the present species, of which I have four specimens for comparison. 



5. Typophorus mexicanns. (Tab. VII. fig. 24.) 



Typophorus meacicanus, Jacoby, P. Z. S. 1876, p. 814 . 



Hab. Mexico, Oaxaca, Guanajuato, Tuxtla {Salle) ; Guatemala, near the city (Salvin *), 

 Capetillo, Duefias (Champion). 



The red head and thorax, violaceous blue elytra, and the rather small size of the 

 insect will easily distinguish it. A variety with a black head and thorax, the latter of 

 which has only the anterior margin fulvous, was also received, in company with numerous 

 normally coloured specimens, from Capetillo : of this variety a dozen specimens were 

 obtained. Those from Capetillo vary somewhat from the Guatemalan type, being 

 shorter and the elytra rather more strongly punctured ; the latter is figured. 



6. Typophorus melanocephalus. 



Typophorus melanocephalus, Jacoby, P. Z. S. 1876, p. 814 . 



Hab. Mexico \ Puebla, Cuernavaca, Guanajuato (Salle) ; Guatemala (coll. Jacoby). 



The black colour and close punctuation of the head, in connexion with the deeply 

 punctate-striate elytra, which are metallic blue, the thorax being fulvous, distinguish 

 well the present species from others with similarly-coloured upper surfaces. 



7. Typophorus erythrocephalus. 



Black ; the first four joints of the antennae and the head and thorax rufous, the latter finely punctured ; elytra 

 metallic blue or green, finely punctate-striate, the punctuation nearly invisible towards the apex. 



Length 2-2| lines. 



cJ . Head extremely finely punctured when seen under a powerful lens, rufous ; antennae two thirds the length 

 of the body, black, the first four joints rufous, the basal one stained with piceous above ; thorax transverse, 

 distinctly widened at the middle, rufous, surface very finely and rather irregularly punctured, the inter- 

 stices somewhat finely rugose or uneven ; scutellum very broad ; elytra distinctly transversely depressed 

 below the base, the punctures much deeper within this depression ; the striae distinct only at the basal 

 portion, but nearly entirely absent below the middle. Underside and legs black, with a slight greenish 

 tint ; femora with a very minute tooth. 



Hab. Mexico, Guanajuato (Duges, coll. SalU). 



Of this species, which differs in size and colour, as well as punctuation, from T. meoci- 

 canus and T. melanocephalus, one male and three female specimens are contained in 

 M. Salle's collection. The latter sex is a little larger, with the antennse shorter and the 

 punctuation of the elytra much stronger, although the apical portion is as smooth as 

 in the male insect. The punctured and at the same time subrugose thorax is a good 

 distinguishing character of the present species.
