158 PHYTOPHAGA. 



Two specimens, a male and a female, from Costa Rica agree well with von Harold's 

 description ; the species may be separated by the entirely red antennae and legs, and by 

 the elytral apex, which is of the same colour, the lateral margins remaining of the 

 ground-colour. I may add to von Harold's description that the female has the elytra 

 simply punctate-striate, double rows of punctures being visible only in the male ; the 

 specimen of the latter sex before me has the thorax nearly impunctate. The size of 

 31 millim. as given by v. Harold is evidently a mistake, as the species has a length of 

 three to three and a half lines, and the author draws attention to the larger size of the 

 insect in comparing it with others. 



7. Chalcophana germari. 



Elongate, convex, rufous; apex of tibiae, tarsi, and the antennae (their two basal joints excepted) black; elytra 

 metallic green, subgeminate punctate-striate, the lateral margin and the apex rufous. 



$. Larger; elytra more distinctly geminate punctate, deeply transversely depressed, the sides with three or 

 four more or less distinct costae. 



Var. Above violaceous blue. 



Length 2|-3| lines. . _ . 



Head rather swollen, the vertex impressed with larger and smaller punctures ; clypeus impunctate, triangular, 

 its anterior margin concave ; antennae two thirds the length of the body, black, the two, and sometimes 

 three, basal joints rufous ; thorax transverse, not narrowed anteriorly, the anterior angles acute and 

 somewhat produced, surface rather distantly punctured, the punctuation resembling that of the head ; 

 scutellum rufous ; elytra with a short longitudinal depression within the humeral callus, strongly, closely, 

 and rather irregularly punctured anteriorly, but the punctures arranged in more regular and double rows 

 towards the apex, the latter as well as the lateral margins narrowly rufous ; underside and legs entirely 

 of this colour, the apex of the anterior and that of the other tibiae (but to a smaller extent), as well as 

 the tarsi, black. 



Hab. Mexico, Jalapa, Orizaba, Cerro de Plumas, Cordova, La Parada, Oaxaca (SalU, 

 Hoge). 



Although closely allied to C. wagneri, C.fratema, and C. consobrina, the present 

 species, which is before me in great numbers, shows sufficient differences to justify its 

 separation. C. fraterna, Har., seems to be the nearest allied form, but is described as 

 entirely devoid of costse (the author does not mention if this applies to both sexes), and 

 as having entirely red legs ; the punctuation is also given as regular. C. consobrina 

 differs by the same want of costse and by the fine punctuation of its elytra, especially 

 near the apex, and C. terminalis by the greater extent of the rufous colour of the elytra 

 and their finer punctuation. I have no doubt that the females before me from the 

 same locality belong to the present species : the elytra are much more regularly gemi- 

 nate punctate-striate ; but the punctures themselves are quite as distinct, and nearly 

 as strongly marked at the apex as at the anterior portion; besides the longitudinal 

 basal depression of the male, there is a distinct and deep transverse one below the base, 

 from which, near the shoulders, three or four very distinct costse run parallel with the 

 lateral margin, the inner one being, however, very short, the following gradually 

 increasing in length, and all of them uniting at a little distance from the apex. By
