JHeteroscinis ornata, sp. n. 



This second species is a considerably smaller bright orange 

 insect, which has a remarkably different general aspect from 

 the last and some structural differences of importance. 



Head (top view) : — Frons and triangle all smooth pale 

 shining yellow, the demarcation between the sides and triangle 

 being difficult to see, but with a suitable illumination the 

 border-row of extremely fine hairs can just be seen ; they 

 define a large triangle with its base across the vertex and 

 slightly rounded tip right up to the front, it being just 

 perceptibly more shining than the rest ; the absolute ocellar 

 area is black. Face all pale yellow, as is the antenna, the 

 2nd joint narrowly bordered with brown, and .the small 

 suborbicular 3rd with a tiny black spot at aristal insertion; 

 the arista is brownish and like that of the last species in 

 structure. Side-view : very like fig. 15, but the head pro- 

 portionately a little longer axially ; a distinct black bristle 

 on hind jowl ; in colour all pale yellow, with orange exserted 

 palp ; hind head all yellow.

llrteroscims ornata, X 22. 



Thorax superficially very different from that of last species, 

 the dorsum being all excessively smooth and brilliantly 

 shining ; the d.-c. lines are occupied by a row of tiny close-set 

 pits carrying very minute black hairs ; in colour it is slightly 

 orange, callus bright yellow, on the dorsal side of the same a 

 tiny black spot; scutellum half as long as thorax, triangular 

 in profile, with slightly rounded sides and sharp point, deeply 

 cut off from thorax, the disc a little duller, pale yellow, and 

 quite flat ; the border of the flat part is edged with brown 

 lines from the tip (these themselves being bordered with a 

 few hairs inside), and these run across the thoracic dorsum in 

 two slightly concave lines nearly to the middle ; the long- 

 black end-bristles stand on quite small papillae ; the sides 

 are also plane and carry the side-spines on still smaller
