150 PHYTOPHAGA. 



close and regular rows, the first two near the suture subgeminate, extreme apex eostate ; another sub- 

 marginal costa extends higher up towards the base ; the interstices between the apical costse scarcely 

 punctured. 



Hab. Nicaragua, Chontales (Janson). 



Although the punctuation of this species is almost the same as that of B. mexicanus, 

 the shape, which is more elongate, and the metallic green of the upperside and the 

 piceous colour below, as well as the stronger punctuation of the elytra, will separate 

 the present insect. 



5. Khabdophorus rugosus. (Tab. VII. fig. 8.) 



Oblong, parallel, convex, fulvous below; above submetallic green or aeneous.; thorax strongly and closely 

 punctured, very broad ; elytra strongly punctate-rugose, the interstices transversely wrinkled. 



Length 3 lines. 



Head broad, flat, closely covered with large and small punctures ; space in front of the clypeus irregularly 

 depressed, the latter anteriorly deeply concave, emarginate ; labrum fulvous ; antennae half the length of 

 the body, fulvous, the last three joints generally piceous ; thorax narrow, nearly three times as broad as 

 long, the sides much and regularly rounded, distinctly marginate, the anterior angles acute and slightly 

 produced outwards ; surface everywhere closely and strongly punctured ; elytra not wider at the base than 

 the thorax, parallel, closely punctate -striate near the suture, the rest very irregularly and strongly 

 punctured, the interstices, especially those at the sides, transversely rugose. 



Hab. Mexico, Cordova, Tuxtla, Playa Vicente {Salle, Hoge). 



The metallic green colour of this species is greatly reduced by the fulvous ground- 

 colour shining through it, in which respect it differs from B. salvini, which is of a 

 bright green colour; in general shape, however, it nearly approaches this species, 

 although rather more parallel-sided ; but the two insects are at once distinguished by 

 the difference in the punctuation of the thorax, which in the present one is strongly 

 and closely punctured, the same part being more finely and distantly punctate in 

 B. salvini. From B. mexicanus the species before us may be separated by the much 

 greater width of the thorax, which gives the insect the appearance of a species of 

 Chrysomela. The punctuation of the female is still more strongly impressed than that of 

 the male insect. Five specimens are before me for comparison, of which one from 

 Cordova is figured. 



6. Khabdophorus guatemalensis. (Tab. VIII. fig. 22.) 



Oblong-ovate, aeneous ; antennae testaceous, the seventh and the two terminal joints black ; thorax finely and 

 closely punctured ; elytra closely geminate punctate-striate, the interstices eostate. 



Length 2| lines. 



Head rather closely and finely punctured, especially at the clypeus, with a fine central groove, ending in a 

 broader depression between the eyes ; labrum light fulvous ; antennae half the length of the body ; thorax 

 narrowly transverse, the sides much deflexed anteriorly, the lateral margin subangulate behind the middle, 

 surface finely and closely punctured, more so at the sides than on the disk, with an obsolete shallow 

 depression at each side ; elytra narrowly oblong, convex, slightly transversely depressed below the base, 

 their apex subacute, surface deeply geminate punctate-striate at the sutural portion, irregularly punctured
