32 THE CANADIAN ENTOMOLOGIST. 



Institute, Pusa, Bihar, India, attacks \'oung (iingclly {Sesamiim 

 indicwn) capsules, producing a wrinkled, twisted gall instead of 

 the fruit. He has figured the adult and gall on page 364 of his 

 work on South Indian Insects, 1914, and classifies this insect as 

 one of the minor pests. He has kindly placed reared specimens, 

 which were labeled South India, Coimbatore. June. 1912, and 1913. 

 at our disposal, and the species is described as new. 



Exuvium — Length 4 mm., a nearly uniform chestnut brown 

 except for the nearly transparent antennal cases, the latter ex- 

 tending to the base of the second abdominal segment, the wing 

 cases to the fourth, and the leg cases to the sixth abdominal seg- 

 ment. The dorsum of the abdominal segments with a scattering, 

 and on segments five to eight, respectively, a somewhat double, 

 transverse row of short, stout spines near the basal third and a 

 similar, single row of rather thickly-set, almost contiguous, longer, 

 stout spines near the middle; terminal segment with the l)asal row 

 of spines distinctly double and scattering, and the distal row ir- 

 regular, there being three on each side of the median line and a 

 compound, lateral, spiny process. 



Male — Length 3 mm. Antennae extending to the fourth 

 abdominal segment, sparsely haired, light browm; 14 segments, the 

 fifth with a length severi times its diameter, the twelfth with a 

 length nearly five times its diameter, the thirteenth and fourteenth 

 segments missing. Palpi; the first segment irregularly and roundly 

 cjuadrate, with a length nearly twice its diameter, the second 

 greatly produced, slender, sparsely setose, and with a length nearly 

 three times that of the first. The mesonotum slaty brown, the 

 submedian lines sparsely haired. Scutellum fuscous yellowish 

 brown with a few setse at the lateral angles, postscutellum a fuscous 

 whitish. Abdomen sparsely haired, light brown, the genitalia 

 fuscous yellowish. Wings hyaline, costa pale straw; halteres 

 basally and apically mostly whitish transparent, the stalk dark 

 brown. Coxie and femora reddish brown, the tibia? and tarsi 

 mostly pale straw; claws long, rather slender, the pulvilli as long 

 as the claws. Genitalia; basal clasp segment short, greatly swollen;
