the lateral depression is broad and submedian. The depressions give a 

 much swollen or torous effect to the rear of the elytra. The relative 

 length of the antennal joints might place this form in sec. i, but the 

 general appearance is such that I have put it next coccinea Baly ; the elytra 

 are sparsely diffusely punctulate, body beneath black. 



D. tœniolescefis, nov. sp. 



Head and thorax rufous yellow; antennse and legs yellow; scutel dark 

 rufous ;.elytra pale yellow, each with 4 elongate black spots, a humeral 

 and subbasal median, and two behind the middle, in the rear of the 

 anterior ones, giving the appearance of 2 interrupted black vittc^, body 

 beneath black. Length, 5 mm. 



One example, Callanga, Peru. 



A very well marked form coming next to tœiiiolata Gahan, from 

 which it differs in the wholly flavous antennae and spotted in place of vittate 

 elytra. The thorax is finely punctulate and has a deep oblique fovea on 

 each side and a third round one at the rear ; the punctures of the elytra 

 are moderate and arranged in obsolete stri^; the subbasal spots do not 

 attain the margin and are a little short of Yz the length of the elytra; the 

 two rear spots end just over the convexity ; the exterior angles of all the 

 spots are rounded; the general appearance on each side of the rear spots 

 on each elytron, is that of an oblong black patch bisected by a narrow 

 yellow stripe. 



D. 4-sigJiata, nov. sp. (Jac. in litt.). 



Head black; antennae black, extreme base and joints S-ii flavous, 

 except extreme tip of 1 1 and base of 8 which are black. Thorax flavous- 

 rufous, wider than long, smooth, obsoletely trifoveate : elytra flavous, rather 

 coarsely and thickly punctate, each side with 5 short viridicyaneous streaks 

 a basal median, a humeral, a lateral and two small postmedian spots, 

 placed on the convexity longitudinally behind the first two anterior 

 streaks. Body below and legs t-estaceous, tibi?e and tarsi fuscous. 

 Length, 6 mm. 



Two examples, Marcapata, Peru. 



Very close apparently to humeralis Gihan. The antennae, however, 

 seem to differ and the markings are viridicyaneous in place of nigro- 

 cyaneous. The species has been distributed with the manuscript name 

 4-signata Jac. and two co-types have been sent me by Messrs. Staudinger &: 

 Bang-Haas. In my two examples the inner basal marks are not joined to
