A long series seen, males prcpoiidtiating, showing scarcely 

 any variation, except in size. The ])enis-sheath of the $ , 

 examined in many specimens, is very different from that o£ 

 any of the allied species dissected.

Elongate, narrow, shining, nigro-pilosc above and beneath ; 

 nigio-cperuleous, the head and ])rotliorax greeni.sh, the elytra 

 witli an oblong spot at the base, the" lateral margins to near 

 the middle, a triangular postmediaii patch on the disc, and a 

 transverse subapical mark, luteous or reddish, the antennaj 

 testaceous to about the middle ; the head and proihorax 

 finely, the elytra rather coarsely punctate. Head not much 

 developed behind the eyes; antennae moderately long in J, 

 short in ? . Prothorax transverse, lounded at the sides in 

 both sexes. Elytra long, subparallel in their basal half.

Described from a pair acquired by the Museum in 1844, 

 the (J labelled with the MS. specihc name hcematostictus. 

 An elongate, narrow, metallic insect, with nigro-cferuleons 

 elytra, which are each marked with three rather large luteous 

 or reddish spots — one basal (oblong), one postniedian (tri- 

 angular), and one subapical (transverse). A larger abraded 

 $ (length 8^ mm.), from Puarcatambo, Peru, too imperfect 

 to name, ditfers from the Brazilian insect in having the elytra 

 less coarsely punctate, and the three spots transverse, the 

 second forming a definite arcuate fascia. A. hcematostictus 

 seems to be nearest allied to A. sexmaculalus^ Vtxiy, from 

 which it is separable by its smaller size, miriower form, and 

 the differently shaped spots on the elytra. The unique male 

 has not been dissected.
