Head and middle joints of antennte black, thorax flavous, transverse, 

 constricted behind, and bifoveate, scutel black, elytra bright bluish green, 

 transversely, rugosely, coarsely punctate with about five elevated costs, 

 lateral margin and apex flavous, beneath and legs flavous, tibiae and tarsi 

 fuscous. ^ with a hollow and protuberance near the sutural apex.

Callanga, Peru, 2 $ , i ? , i $ ? 



Very near viridipejinis Jac. (type in my collection). The main dif- 

 ference aside from a little brighter colour, is the wholly black head in 

 the c? • The species has been distributed with the manuscript name 

 alterjiata Jac. of the pair sent to me as co-types by Messrs. Staudinger 

 & Bang-Haas, the 9 seems to be probably a different species, the lower 

 part of the face being yellow, the antennae wholly fuscous testaceous and 

 parts of the body beneath black. 



Head smooth, with a fovea, palpi flavous, antennae more than half the 

 length of the body, black, first joint testaceous, 2nd testaceous below, 

 8-9 and part of 10 flavous, thorax transverse very narrow, moderately 

 coarsely punctate (like viridipentiis, though IMr. Jacoby's description says 

 the reverse), elytra moderately widened behind with about 5 distinctly 

 elevated costae which vanish at or before reaching the testaceous tip, 

 which is broad with a deep sutural excavation similar to that of other species 

 of this group (C. Baly's paper). The legs are fuscous on the upper outsides. 



D. ?iigrotibialis, nov. sp. (Jac. in litt). 



Head black, mouth parts yellow, antennae black with last three joints 

 pallid, thorax transverse, flavous, deeply depressed, trifoveate, the depres- 

 sion more or less piceous, scutel smooth black, elytra black, elongate, 

 nearly parallel, thickly, coarsely, corrugately punctate, black, the lateral 

 margin narrowly flavous, the c^ with cariniform process on the con- 

 vexity near the suture, below and legs flavous, tibiae and tarsi black. 

 Length, 7-8 mm. 



Eight examples, Marcapata, Peru.
