Type & and 9 in Indian Museum. 



N.B. — The South Indian example, which has to be erected 

 as the type 2 , the remaining 9 being incomplete, has black 

 bands on the abdomen instead of spots, but this is the only differ- 

 ence. It is somewhat akin to P. doleschalli, Os. Sac. 



Pachyrhina consimilis, mihi, sp. nov 

 cf 9 . Himalayas. Long. 9 — 14 mm. 



Head deep chrome- ^^ellow ; proboscis generally a little 

 lighter,, with a wide dark brown stripe on upper side and dark 

 brown labella ; palpi also dark brown. Back of head at junction 

 with thorax, with a dark brown triangular mark. Antennal scape 

 deep 3'ellow, flagellum black, the joints distinctly but only slightly 

 thickened at the base, verticillate hairs short. Sometimes in the 

 $ the antenna is dark brown, the second joint of the scape 

 being also brown tinged. 



Thorax deep chrome-yellow. The three dorsal stripes deep 

 black, shining, very clear cut ; the median one, which attains the 

 anterior margin, more or less extended downwards along the edge 

 behind the prothorax, on which there is often a brown spot or streak 

 on each side in this vicinity. The outer dorsal stripes turn sharply 

 down over the sides at their tips, their limits sharply defined. The 

 post-sutural elongate spots are equall}* deep shining black and 

 clearly cut, reaching from above the root of the wing to the 

 scutellum. Scutellum light livid brown, sometimes yellowish, 

 with or without a brownish or blackish mark in the centre. Me- 

 tanotum bright chrome-yellow, with a more or less distinct narrow 

 or moderately wide brownish longitudinal stripe. Sides of thorax 

 rather lighter yellow, sternopleurae with a tawny brown, semi- 

 transparent spot on the upper and lower part, leaving the middle 

 concolorous. 



Abdomen normally bright or deep yellow, with, in the c^ , 

 a longitudinal median black stripe of moderate width, composed 

 of a row of elongate spots more or less united to one another, the 

 black colour towards the tip spreading more or less over the whole 

 dorsal surface. A lateral narrow stripe similarly formed. 



In the 5 , the abdomen is wrinkled and bears a large, more or 

 less square, blackish spot on each segment, generally of sufficient 

 size to form an apparently continuous dorsal stripe, but the 

 posterior margin itself of each segment is yellow and well defined. 

 There are also numerous irregularly placed small black spots between 

 the dorsal stripe and the rather broader (than in the cf> ) lateral 

 stripe each side. Belly similar to dorsal surface. 



Genitalia in cf complex : a side plate is present, and a small 

 yellow V-shaped ventral plate, protecting a somewhat conspicuous 

 keel-like protuberance immediately above it, joined to the large 

 swollen base of the claspers. 



Legs variable; normally yellow, the femora becoming brownish
