204 RHYPARIDA PINGUIS. 



convex ; the insect had therefore be placed better in the 

 genus rJiytorus Jacoby (Ann. Mus. Genoa. XX. 1884). 

 It is possible that the species described under this name 

 by myself is but the male form of the present insect. 



Abirus subrugosus, n. sp. 



Metallic green ; head finely and closely punctured , semi- 

 pubescent ; antennae dark violaceous blue, the last five joints 

 strongly dilated; thorax strongly and closely punctured; 

 elytra finely and regularly puuctate-striate at the inner disk , 

 strongly transversely rugose at the sides. — Length 4 lines. 



Head somewhat swollen , very closely and finely punc- 

 tured; middle of the front with an obsolete longitudinal 

 groove , sparingly covered with fulvous pubescence ; epistome 

 not separated from the front , a little more strongly punc- 

 tured than the latter , its anterior margin slightly concave- 

 emarginate ; labrum metallic green ; antennae half the length 

 of the body , the first joint metallic green , the following 

 violaceous , last 5 joints very strongly dilated and flatte- 

 ned; thorax transversely convex, strongly deflexed at the 

 sides, all the angles with a distinct tubercle, surface clo- 

 sely and evenly covered throughout with oblong deep 

 punctures, rather more strongly impressed at the sides 

 than at the disk ; scutellum distinctly broader than long , 

 violaceous ; elytra subcylindrical , distinctly depressed below 

 the base , the latter having a somewhat raised appearance, 

 the entire inner half of their disk is finely and regularly 

 punctate-striate , the outer portion strongly transversely 

 strigose; these elevated strigae assume towards the apex 

 the shape of single irregular tubercles which are placed on 

 a slightly raised longitudinal ridge ; under surface sparingly 

 clothed with fulvous pubescence. 



This species , of which but a single specimen is before 

 me, diff'ers from A. (Dermorhytis) elegans Baly in the very 

 regular punctuation of the inner disk of the elytra, the
