94 JOUENAL OF ENTOMOLOGY AND ZOOLOGY 



slender, slightly curved and tapering to a subtruncate, spinose 

 apex; style moderately long, slender, tapering, narrowly 

 rounded apically. 



Female — Length 1.5 mm. Antennae hardly extending to the 

 base of the abdomen, sparsely haired, dark brown; fourteen 

 sessile seg-ments, the fifth with a lengih one-fourth greater than 

 its diameter, the terminal segment with a length more than 

 thrice its diameter and composed of three closely fused seg- 

 ments. Palpi — First segment broadly ovate, the second slender, 

 with a length about thrice its diameter. Mesonotum shining 

 dark brown, the submedian lines thickly white-haired. Scutellum 

 and postscutellum fuscous yellowish. Abdomen dark brown, 

 the segments narrowly margined posteriori}' with silvery white, 

 the markings on the first two rudimentary, those on the third, 

 fourth, fifth and sixth almost forming submedian spots, those 

 on the seventh diffuse; venter with the small sclerites dark 

 brown, the incisures and pleurae fuscous yellowish. Ovipositor 

 yellowish, nearly as long as the abdomen when extended, the 

 basal portion fleshy, the distal third chitinized, cultrate and 

 with a distinct expansion near the middle. The claws in this 

 sex are distinctly heavier than in the male and about as long 

 as the pulvilli. 



Type—C. a2477. 



This viuique type is most interesting because of certain 

 synthetic combinations, namely, the Lasioptera type of wing 

 and antenna with the simple claws and the bladelike ovipositor, 

 the two latter suggesting very strongly an affinity with Asphon- 

 dylia. In the case of the ovipositor we believe this modification 

 to be one of minor significance and evidently an adaptation 

 enabling the female to deposit her eggs within the tissues of the 

 host plant. The absence or almost total absence of teeth on the 

 claws is simply one remove further from what we find in 

 Baldratia with claws either simple or toothed. The combina- 

 tion of characters is significant and yet the obvious dominance 

 of the Lasioptera structures leads us to class this genus with 

 the LasiopterarifE rather than to place it in a separate tribe, 

 Aplonyxini, as proposed by Dr. Perez, the discoverer of 

 Aploayx.
