1903.J SOUTH- AMERICAN COLEOPTERA. 47 



transverse metallic green bands, one below the base, the other, of 

 oblique shape, at the middle. 



Length 10-11 millim. 



Head minutely and closely punctured, obscure seneous, opaque ; 

 antennae short, black, the basal two joints below and the apex of 

 the last flavous; thorax about twice as broad as long, the sides 

 straight at the base, rovinded anteriorly, the anterior angles 

 mucronate, extending to the end of the eyes, the extreme latei-al 

 margins flavous, the disc coloured like the head, very closely and 

 finely punctured, the punctation even throughout ; scutellum 

 black ; elytra pale testaceous, closely, strongly, and irregularly 

 punctured, covered with numerous, closely placed, green, small 

 spots of irregular shape and size, below the base a naiTow trans- 

 verse metallic green band extends across the suture but not to the 

 lateral margins, another similar band of strongly oblique direction 

 is placed at the middle and is slightly abbreviated at each end ; 

 mesosternal process long and robust. 



Hah. Peru. (Two specimens.) 



Sevei-al similarly marked species are known, but they are either 

 of much larger size or devoid of the thoracic flavous margins ; in 

 D. hifasciata Fab. and D. macidata Oliv. the anterior elytral 

 bands are curved upwards and the suture is likewise provided with 

 an jeneous stripe ; the elytral epipleurse in the present species are 

 entirely flavous. 



DORYPHORA FASCIATIPENNIS, Sp. UOV. 



Greenish seneous, the thorax remotely punctured ; elytra closely 

 geminate punctate-striate, a subsutural and marginal longitudinal 

 narrow stripe, connected by a transverse one below the middle, 

 flavous. 



Length 8 millim. 



Head finely and sparingly j)unctured ; antennae greenish aeneous, 

 the terminal joints moderately widened, twice as long as broad ; 

 thorax sparingly punctured at the middle, the sides impunctate ; 

 elytra evenly convex, strongly and closely geminate punctate- 

 sti-iate, the first two rows near the suture, single, the flavous 

 bands narrow, the sutural one placed on the third interspace, the 

 latei-al one close to the margin which remains of the ground-colour, 

 both bands are joined at the apex and connected below the middle 

 by another short transverse band ; the mesosternal process very 

 short, claw-ioints unarmed. 



Hcfjh. Balzapamba, Ecuador. 



A small beetle, resembling in its markings several species of the 

 genera Zygogy-cmima and Cosmogramma, but a true Doryphora. 



SXILODES FLAVOFASCIATA, Sp. nOV. 



Black, the labrum, palpi, and basal joints of the antennae flavous ; 

 thorax opaque, nearly impunctate ; elytra similarly sculptured, 

 black, a nai'i-ow transverse and finely divided band at the base,
