IV. Noles on Fig Insects, including descriptions of three new 

 species and a new Blastophagine genus. By James 

 Waterston, B.D., B.Sc. 



[Read Fobruary 4th, 1020.] 



The Imperial Bureau of Entomology has recently received 

 a small consignment of Fig Insects from Uganda, collected 

 by Dr. G. D. H. Carpenter. In working out these and 

 other insects of the same family, already in the collections 

 of the Bureau, I have made some notes which seem worth 

 recording with the descriptions of the new species. Not 

 the least interesting occurrence is that of Blastophaga 

 psenes L. at Pretoria in 1919. One would like to know 

 whether the species has been dehberately introduced or 

 whether it has arrived more fortuitously.

Compared with specimens from Montpellier (S. France) 

 the above examples have the apical joint of the club a 

 little shorter, and there are some minute differences in 

 chaetotaxy which apjoear to be well within the range of 

 variation shown in this species.

In this example the first joint of the mid tarsus is |- 

 longer than the 2nd. In the head the length (depth) and 

 width are sub-equal. The 2nd joint of the antenna is 

 distinctly longer than wide. I have therefore assigned it 

 to B. allotriozoonoides Grnd., though the shape of the 

 scape does not quite tally with Grandi's figure (Bull. Soc. 

 Ent. Ital., xviii, fig. 1, p. 6, 1917).
