7. Descriptions of new Species of Phytophagous Coleoptera. 

 By Martin Jacoby. 



[Received January 10, 1878.] 



Family Evmolpid*. 

 Genus Chalcophana. 



1. Chalcophana rufipennis, sp. nov. 



Above, shining bright rufous ; below, black ; legs testaceous ; 

 head with a median depression, impunctate, labrum and antennae 

 light testaceous ; thorax finely and very sparingly punctate, together 

 with the head rufous ; elytra of the same colour, distinctly and 

 regularly punctate-striate on the disk, more irregular towards the 

 sides, where also three distinct ribs or costae are visible running 

 parallel to each other. Underside black, with a metallic green tint; 

 legs and tarsi yellowish or testaceous. 



Length 4 lines. 



Hah. Costa Rica. 



Collected by Mr. Rogers. 



This species is closely allied to C. discolor of v. Harold, but 

 differs abundantly in the coloration of the antennae, the underside, 

 and legs. 



2. Chalcophana costatipennis, sp. nov. 



Upper aud underside rufous testaceous ; antennae black, the basal 

 three joints ferruginous ; femora red ; tibiae and tarsi black ; head 

 minutely punctured, with a fovea between the eyes ; thorax with a 

 few minute punctures ; scutellum smooth ; elytra each with about 

 seven distinct costae, all of which, with the exception of the fifth 

 and sixth, commence below the transverse and deeply marked basal 

 depression ; the fourth, fifth, and sixth costae united at a little dis- 

 tance from the apex ; the interstices deeply punctate, the punctures 

 united in pairs. 



Length, 3 to 3^ lines. 



Hab. Chontales, Nicaragua. 



This species, although closely allied to 0. discolor, Harold, and 

 C. rufipennis above described, is distinguished from both by the 

 strongly raised costae on the entire disk of the elytra and by the 

 entirely black tibiae. 



Genus Colaspoides, Castelnau. 



3. Colaspoides viridicollis, sp. nov. 



Oblong-ovate, convex, fulvous above ; head, thorax, and a broad 

 margin round the elytra bright metallic green ; head sparingly but 

 deeply punctate, with a deep longitudinal groove ; antennae with 

 the first six joints, the labrum, and palpi fulvous, the last four joints 

 of the antennae much depressed and widened, of a fuscous colour ; 

 thorax with the anterior and posterior margin gradually produced 

 in the middle, the sides evenly rounded, with a shallow but distinct
