Xanthopimpla sikkimensis, Cameron, Tijds. Ent. 1907, p. 100 ($). 



c? $ . A luteous species, with black markings and the second 

 segment immaculate. Head with the face closely and strongly, 

 clypeus 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. Antenna; black, with the scape centrally flavous, and the 

 flagellum basally piceous, beneath. Thorax smooth, with the 

 notauli only apically distinct and the mesopleurae 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 

 seutellurn ; metanotum with a basal transverse band which is 

 centrally constricted, black. Areola large and hexagonal ; basal 

 external areas 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.). Legs 

 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 

 apex, a slightly larger one on the tibiae, and the apices of the 

 tarsi, black. Wings hyaline, with their apices narrowly inf umate ; 

 areolet shortly petiolate, emitting the recurrent nervure very 

 slightly beyond its centre. 



Length 10 millim. 



SIKKIM (Bingham). 



The size of the black markings in the $ is said to be of variable 

 extent, and sometimes the intermediate tibiae are also externally 

 black-marked. 



The female was described from material collected by Col. Bing 

 ham 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 : J. T. Jenkins."
