XA.NTHOPIMPLA.. 115 



and their tarsi, black. Wings hyaline, with their apices narrowly 

 infuinate ; stigma and nervures black ; areolet small, triangular 

 and subpetiolate, emitting the recurrent nervure from near its 

 apex. 



Length 12 millim. 



SIKKIM (Bingham). 



Type. Location unknown. 



01. Xanthopimpla nssnia, sp. 11. 



5 . A species of average size, flavescent, with black thoracic, 

 cephalic and pedal dots, and the abdomen with three series of 

 duplicated bold marks on the central segments, the first and seventh 

 each with a transverse band, and the second with two spots, 

 black. Mesonotum centrally longitudinally canaliculate in front. 

 Terebra shorter than basal segment. Wings with no areolet. 



Length 12 millim. 



"INDIA" (Capt. Boys}. 



No detailed description of this species is needed, since the 

 incomplete rnetathoracic areola resembles only that of the two 

 preceding species, from both of which it is at once distinguished 

 by the centrally sulcate mesonotum, entirely wanting areolet, 

 basally normal mesosternum, abdominal coloration and very short 

 terebra. The sulcate mesonotum is similar to that of X. tri- 

 fasciata, which has the areola entire, the areolet normal and the 

 alar apices distinctly infumate. 



I have seen but a single female of this abnormal species, in 

 the collection of the Hope Department of the University Museum, 

 Oxford. 



62. Xanthopimpla immaculata, sp. n. 



<$ $ . A small, entirely pale fulvous species, with only the eyes, 

 ocelli and terebra black ; the stigma testaceous and the apical 

 abscissa of the radius strongly sinuate centrally. 



Length 0-8 millim. 



A detailed description of this species would be superfluous, 

 since it is so closely related to Xanthopimpla pedator as to render 

 it doubtful, until minute structural points be examined, whether 

 it really be more than a colour variety of that species. Super- 

 ficially it is at once recognised by its entirely immaculate thorax, 

 abdomen and legs, small size and pale antennae ; but a careful 

 examination will reveal that its terebra is much shorter than in 

 any of its allies, the radius is distinctly more sinuate and the 

 stigma uniformly testaceous, and not piceous. That it is really 

 distinct from X. pedator, however, I am not fully persuaded, 

 since I have seen a specimen from Chapra, in Bengal, which 

 combines the sinuate radius and the immaculate thorax with black 

 hind tibial bases and abdominal spots, though only 8 millim. in 

 length.
