cases of mimicry from Elopura. 371 



The bee : Size, If in. long ; expanse of wings, 2f in. 

 Antennae, f in. ; bind legs nearly as long as tbe body 

 and hairy. Colour : Antennae black ; head yellow ; 

 upper part of thorax black, lower part yellow, extending 

 to the 1st segment of the body ; rest of the body black, 

 with a conspicuous yellow band in the middle ; wings of 

 a uniform metallic blue- black ; the anal angle of the 

 hind wing projected. The colours of both bee and moth 

 were identical when alive, but since their capture the 

 yellow on the bee has changed to a brownish tint, and 



abruptly ; disco-cellular veinlet obsolete ; median branches widely 

 separated ; subinedian and internal veins widely divergent ; head 

 large, broad, with prominent eyes ; palpi large, recurved, densely 

 scaled, with acute terminal joint; antennae long, very thick, 

 smootli, coarsely pectinated in front (not bipectinated) ; tapering, 

 and with a small terminal pencil of hak at the distal extremity ; 

 collar broad ; thorax very robust and convex ; abdomen long, 

 coarsely scaled, especially towards the anal extremity, which has 

 an almost woolly appearance owing to the numerous long pro- 

 jecting scales which clothe the last three segments ; anterior legs 

 rather short and thick, the tibiie broad and coarsely scaled ; pos- 

 terior legs densely clothed with coarse hair-scales, as in Melittia. 



Scoliomima insignis, n. s. 



An admirable mimic of Triscolia patricialis ; the primaries 

 metalhc sap-gi-een, with the apical border from fourth subcostal 

 branch to third median bronze-brown (forming an almost triangular 

 patch of this colour) ; secondaries bronze-brown, but nearly the 

 whole basal half occupied by a broad patch of metallic sap-green ; 

 a transparent white spot at base of interno -median area ; nearly 

 the whole of the area enclosed between the submedian and internal 

 veins also hyalme white ; head black-brown, antennae blue-black ; 

 palpi clxrome-yellow, with black terminal joint ; collar brilliant 

 golden yellow ; thorax black-brown, with two patches of yellow 

 scales at the back ; abdomen blue-black, with a golden-yellow ])elt 

 on the basal segment and another on the 4th segment ; under 

 surface of body black, extremity of femora of posterior legs with a 

 few white hairs ; tarsi fringed with white hah's ; expanse of wings, 

 56 mm. 



The scales on the collar of this species are bent, in order to catch 

 the light, and thus render the resemblance which this yellow l)and 

 bears to that on the back of the head of the Triscolia more 

 striking ; the hairy legs no doubt help to make up the deficiency in 

 the width of the abdomen needed to complete the similarity of 

 the moth to the wasp. 



The genus Scoliomima agrees best with Toosa, Walk., in form 

 of wings, witli Melittia in the clothing of its legs ; but in its 

 antennae it comes nearer to Tarsa, though very distinct, owing to 

 the unipectinate character of these organs. It should stand 

 between Toosa and Melittia, — Arthur G. Butler.
