Gangtok, Sikkim, 6150 ft., 10.ix.09: Siliguri, N. Beugal, 18- 

 20. vii. 07 ; all in the Indian Museum. In the Pusa collection are 

 two males from Pusa taken 29. vii. 07 and 8. ix. 08. The species 

 also occurs in Japan. 



Type 6 in the Indian Museum. 



The two males in the Pusa collection have the median dorsal 

 stripe brownish and indistinct (semi-transparent) in front, although 

 equally well-defined and shining as in the typical form. 



Some specimens taken by me at Yokohama, 20-26. vi. 06, have 

 the scutellum all black, the black line on the mesonotum much 

 wider and darker, and a distinct small oblong black spot on each 

 side of the collare nearly in front of the median thoracic stripe. 

 There can be little doubt they belong to the present species. 



245. Pachyrhina puncticornis, sp. uov. 



This form is ranked as a separate species, but may possibly he 

 only a variety of P. serricornis, with which it agrees in most of its 

 characters. As only one specimen is present, exact judgment is 

 difficult. . ^ ^. u 



c? . B^ead : the antenufe are as in P. serricornis, but the base 

 only of each flagellar joint after the 1st is pale yellow, the 1st 

 flagellar joint being yellowish on the basal half. Thorax: the 

 median dorsal thoracic stripe is rather bright bro\\-n throughout 

 its entire length, the side stripes are very dark shining brown, 

 not curved outwards and downwards at the tip, nor carried 

 forward as two fine lines each; the short post-sutural stripes are 

 turned downwards towards the base of the wings, where they 

 become much darker, but show no trace of being continued along 

 the side of the thorax towards the shoulder. Scutellum appa- 

 rently pale brownish yellow (damaged by the pin) ; metanotum 

 and base of abdomen, also the posterior part of the thorax, bright 

 light yellow. Ahdomen mainly yellowish, the middle segments 

 and the dorsum of some of the succeeding ones blackish. Geni- 

 talia apparently as in P. serricornis, perhaps comparatively a little 

 smaller, but as they are considerably withdrawn their exact con- 

 struction is not easily visible ; they are rather bright brownish 

 yellow in colour and considerably pubescent ; the dorsal plate, if 

 present, must be very small. 



Length 10 millim. 



Described from a single specimen from Siliguri, at the base ot 

 the Darjihng Himalayas, 30. vi. OS. 



Type in the Indian Museum. 



246. Pachyrhina pleurinotata, sp. nov. 



This species is closely allied to P. serricornis, but is certainly 

 distinct. The points of difference are as follows : — 



cj $ : Head : proboscis with a small black streak on the upperside
