COPROPORUS IRIDESCENS D. Sp. 



Black, siibdepressed, black shininor. iridescent, all the 

 margins of the thorax indeterminately ferruginous; elytra 

 with large indeterminate ferruginous patch on the disc extend- 

 ing to the posterior border, lateral margin ferruginous. 



Antennae with the first three joints testaceous. Legs 

 reddish testaceous. Length (in well extended example) 3.5 

 mm., of the same size and build as C. disripennis Fauv., but 

 the elytra mark is less defined and extends up the posterior 

 border, the sides are less narrowly impressed, the lateral 

 margin narrowly explanate. the puncturation of the fore parts 

 is even finer and more sparing, that of the abdomen finer 

 and more obsolete : the whole insect is very distinctly 

 iridescent. Head transverse, much narrower than the thorax, 

 very obsoletely and extremely sparingly punctured, glabrous. 

 AntenncTB slender, not much thickened toAvards the apex, the 

 3rd joint elongate, longer than '2nd. 4th to 6th longer than 

 broad, gradually decreasing in length 7th to 10th about as long 

 as broad, 11th oval, nearly as long as the two preceding together. 

 Thorax strongly transverse, the sides evenly rounded and 

 narrowed from the base, posterior angles rounded, extremely 

 finely and sparingly punctured. Elytra a little longer but 

 scarcely broader than the thorax, the sides feebly and evenly 

 rounded, slightly transverse, narrowly longitudinally impressed 

 at the sides which are ferruginous and slightly explanate ; the 

 base and around the scutelhim pitchy, the disc largely 

 ferruginous as above described. Abdomen pointed, black 

 iridescent, closely, finely obs;oletely punctured with very short 

 and very sparing pubescence. Mesosternum keeled ; 1st 

 joint of posterior tarsi elongate. 



cf . 8th dorsal segment with four long lanciform processes 

 of which the outer are stouter than the inner, each with a 

 long seta at apex. 6th ventral segment obliquely truncate 

 at the sides, deeply triangularly excised in the middle, the 

 lateral angles of the excision with a long seta, lateral margins 

 of segment dentiform and with a seta.
