THE CANADIAN ENTOMOLOGIST. 347 



As it will be seen from the above description of the larvse, these were 

 much different from those of incorrupta received from Mr. Marmont. 



ViTTATA. — Another mature larva of this species came into the writer's 

 hands the past season. This was found at Ottawa by Mr. J. W. Baldwin, 

 under a piece of slone, on April 20. This larva answered in every way 

 to the description which appeared in June, 1903, in the above-mentioned 

 article^ and no additional characters were observed. 



On April 27 it spun a few threads of silk, and by the 29th had woven 

 a slender cocoon. By the morning of May i it had changed to pupa. 

 The moth, a (^ , emerged May 26. 'I'his larva had doubtless hibernated 

 in the mature stage. 



A NEW SUBAPTEROUS TIPULID FROM NEW MEXICO. 



BY D. W. COQUILLETT, WASHINGTON, D.C. 



Over a year ago the writer received from Prof T. D. A. Cockerell, 

 for naming, a pair of Tipulids with aborted wings, taken on the summit of 

 the Las Vegas Mts., in New Mexico. I suspected that they belonged to 

 some normally long-winged form, but repeated comparisons have failed to 

 convince me that they belong to any of those represented in the National 

 Museum. They closely resemble Limnophila costata, Coq., which also 

 inhabits high altitudes in the same region, but the joints of the antennoe 

 are much shorter and broader, besides other differences. The i6-jointed 

 antennae, absence of a frontal gibbosity, the comparatively short terminal 

 joint of the palpi, glabrous eyes and spurred tibise seem to ally this form 

 more to the genus Limnophila than to any other genus known to me. 

 As Prof. Cockerell wishes to refer to it in a forthcoming paper, the new 

 form may be characterized as follows : 



Limnophila .? aspidoptera, n. sp. — Black, the bases of the antennae, 

 mouth-parts, sutures of thorax, lateral margins of abdomen, stems of 

 halteres, bases of the femora, tibiae and tarsi, ovipositor of female and 

 inner portion of male hypopygium, yellow. Head and body gray prui- 

 nose, unmarked. Antennae reaching to base of wings, rather robust, the 

 second joint less than twice as long as wide, the fourth slightly wider than 

 long, the following joints becoming successively longer than wide. Wings 

 aborted, slightly shorter than the halteres, yellow on the basal half, the 

 remainder chiefly brown. Halteres considerably elongated. Male claspers 

 consist of a fieshy basal piece, to the inner side of which is attached a 

 three-pronged, chitinous process. Ovipositor of female of nearly a uni- 

 form width, curved toward the apex, the latter bluntly rounded. 



Length II mm. A specimen of each sex collected June 28. Type 

 No. 9033, U. S. National Museum. 



October, 1905.
