Xanthopimpla sikkimensis, Cameron, Tijds. Eut. 1907, p. 100 (2). 



J' 2 . A luteous species, with blaclv markings and the second 

 segment immaculate. Head with the face closely and strongly, 

 elypeus much more sparsely, punctate ; ocellar region with an 

 elongate triangular black patch from the centre of the frons. 

 which is continuous with a larger semicircular occipital black 

 mark. Antenncv. black, with the scape centrally flavous, and the 

 flagellum basally piceous, beneath. Thorax smooth, with the 

 notauli only apically distinct and the mesopleurte obsoletely 

 punctate ; mesonotum with a broad transverse apical band which 

 has its apex roundly trilobate, with the lobes of equal size, and 

 a large semicircular mark which covers the base and touches the 

 scutellum ; metanotum with a basal transverse band which is 

 centrally constricted, black. Areola large and hexagonal ; basal 

 external area^ large, parallel-sided, and apically rounded ; denti- 

 paral areas quadrangular and externally widened. Abdomen 

 luteous, with black markings thus : — first segment with two 

 irregular apical marks, which are apically united by a slender 

 and irregular transverse band ; third with a broad transverse line 

 on the basal half, which is rounded and slightly constricted 

 basally in the centre and is apically transverse ; fourth with two 

 broad lines, which are basally rounded and apically transverse ; 

 fifth with two slightly shorter lines, which are further apart than 

 those on the fourth and are transverse at both base and apex ; 

 sixth with small basal lateral spots; seventh with a broad trans- 

 verse basal line. Basal segments about one-fourth longer than 

 broad, the remainder transverse, with the central ones weakly 

 punctate : incisions, and especially the central, superficial and 

 weakly crenulate ; terebra distinctly longer than the four basal 

 joints of the hind tarsi or one-fifth of the body (2 millim.). Ler/s 

 luteous ; hind ones with the basal joint of the trochanters, two 

 somewhat elongate oval lines on the inner and outer half of the 

 femora (of which the inner is the larger), a narrow line at their 

 a])ex, a slightly larger one on the tibiae, and the apices of the 

 tarsi, black. Wings hyaline, with their apices narrowly iufumate ; 

 areolet shortly petiolate, emitting the recurrent nervure very 

 slightly beyond its centre. 



Length 10 millim.

The size of the black marldngs in the 2 is said to be of variable 

 extent, and sometimes the intermediate tibite are also externally 

 black-marked. 



The female was described from material collected by Col. Bing 

 bam in the Himalayas of Sikkim. There is in the Calcutta 

 Museum a specimen, which I here place as the male of this 

 species with some confidence, since it differs from the description 

 •of the female in little but its immaculate fourth and sixth seg- 

 ments ; it is labelled " Kankondigee, 24 Perghs. Sunderbuns, 

 15th November 1909 ; /. T. Jenkins."
