498 NOTES ON THE GENUS STIGMODERA, 



fasciae, a posthumeral arcuately produced forward to the shoulders 

 (not reaching the base or sides), and sometimes interrupted on 

 each elytron, a postmedian fascia of irregular shape, widening at 

 the suture and sides (but not extending to the sides), the third 

 shorter than preceding, sometimes interrupted near the suture; 

 extreme apex and posterior part of suture blue; underside yellow, 

 the prosternum, mesosternum (and its epimeron) and abdominal 

 segments with narrow green border, antennas coppery, scutellum 

 very nitid metallic green, legs green (the femora with underside 

 and preapical ring red). 



Head coarsely, not very closely, punctate, frontal depression 

 slight, pronotum convex, apex a little produced in centre and at 

 angles, sides moderately rounded, a little sinuate behind, more 

 strongly converging anteriorly, posterior angles acute, slightly 

 depressed and produced beyond the shoulders of elytra, base 

 bisinuate, strongly, not very closely, punctate (^ more coarsely 

 and distantly than ^); a smooth median line (coarsely punctured 

 on its anterior part), two basal fovese near sides (sometimes with 

 two small foveae on disc); scutellum shield-shaped, smooth. Elytra 

 moderately sinuate, more than twice as long as wide, striate- 

 punctate, the punctui'es in strias only evident on anterior portion, 

 intervals convex and sparsely punctate, apex rounded, not produced 

 or spinose. iSternum densely, legs and abdomen less densely 

 clothed with whitish hair. Dimensions: 15-22 x 5-8"25 mm.

Closely allied to ^S'. Yarrelll Lap. it Gor., from which it differs 

 in the following particulars : (1) Size. The average dimensions of 

 three specimens of S. Yarrelli, in my possession, are '2.'6^ x 9 mm. 

 The average of six specimens of varicoUis gives ITg-xG^mm. 

 (2)Colour. li\S. i 'arre/^i, the pronotum is blue (rarely with small 

 yellow spots near base), with yellow border. In S. varicoUis, 

 the pronotum is red, the green part varying in extent, so that no 

 two specimens are alike. In some, the green only occurs in 

 patches at the apex, and narrow border at the base; in others, it 

 mure or less covers the discal portion, In S. YarreUi, the ground- 

 colour of elytra is yellow, with the postmedian fascia extending
