ME. E. SAUNDEKS ON NEW SPECIES OE STIGMODERA. 469 



the colour widening as it approaches the base ; elytra black, with 

 a cyaneous tinge, with a wide transverse band on each, starting 

 from just behind the shoulder, but not reaching the suture, its lower 

 margin being about two-thirds of the entire length of the elytra from 

 the base ; in the specimen before me the yellow runs up in front of the 

 shoulder and nearly touches the base ; but this character is liable to 

 great variation ; there is also an oval transverse spot of the same 

 colour midway between it and the apex. Beneath black ; sides of 

 the fii'st three abdominal segments, and the whole of the last two, 

 testaceous; legs and antennas cyaneous. 



Head deeply punctured, fm'rowed between the eyes. Thorax once and 

 two-thirds as long as the base ; anterior margin nearly straight, half 

 as long as the base ; sides diverging rapidly for two-thirds of their 

 length, then converging to the base, thus forming a strongly marked 

 angle on each; base straight; surface punctured with a very faint 

 smooth dorsal line. Elytra puncLite-striate, once and two-thirds as 

 long as wide ; sides slightly sinuate above the middle ; apex of each 

 obliquely truncate. Beneath and legs punctured, with a few scattered 

 hairs. 



Length 8-9 lines, bi'eadth S-S^.

Stigmodera. marginicollis. (Plate X. fig. 21.) 



Capite et thorace cyaneo-nigris, hujus lateribus flavis ; elytris nigris, 

 duabus fasciis angustis utrinque fiavis ; subtus sanguinea, femoribus 

 cj'aneis. 



Head brassy-green. Thorax and elytra cyaneous black, the former with 

 its lateral margins, the latter with two bands on each, not reaching 

 the suture, ochraceous, one of these being placed just above the 

 middle, the other nearly midway between it and the apex. Be- 

 neath and femora fulvous ; the tips of latter, the tibiae, tarsi, and 

 antennae cyaneous green. 



Head largely and deeply punctured, excavated between the eyes. 

 Thorax not quite twice as broad as long at the base ; anterior margin 

 slightly emarginate, half as long as the base ; sides diverging rapidly 

 for two-thirds of their length, thence converging to posterior angles ; 

 base slightly sinuate; disk convex, punctured with a faint dorsal 

 hne, the punctuation of the sides rather deeper, which each bear a 

 slight elongate fovea which runs parallel to the lateral margin just 

 above the posterior angle. Elytra punctate-striate, a little more than 

 once and a half as long as wide, base slightly narrower than the 

 thorax, widening considerably at the shoulders, sinuate below them, 

 and swelling out again behind the middle ; apex of each bidentate. 

 Beneath and legs punctured, covered with short white hairs. 



Length 10 lines, breadth 4.
