Leskia Desv. and allies. 



While reviewing Dr. Townsend's recent revision 1 of the sev- 

 eral species included under Leskia analis Say, by the late Mr. D. 

 W. Coquillett, it was evident to the writer, that errors certainly 

 existed in the conclusions as arrived at by Dr. Townsend. 



In attempting to diagnose Mr. Coquillett's study of the genus 

 Leskia, it seems unquestionably apparent that he first included 

 and erroneously determined Leskiomima tenera Wied. as Leskia 

 analis of Say. He then described Myobia depile.- Later dis- 

 covering his error he properly placed Wiedemann's tenera in the 

 genus Leskiomima and made his depile a synonym of Leskia 

 analis. Since the type of Say's analis is not in existence, to my 

 knowledge, and must thus remain an unknown factor, it is evi- 

 dently proper to recognize Dr. Townsend's MyoUobsis similis, 

 which is at least, a recognizable species. Myobia depile Coq., 

 however, has been entirely overlooked in the paper under con- 

 sideration. 



Mr. C. W. Johnson has very kindly afforded the writer the 

 opportunity of examining one of the types of Myobia depile Coq., 

 and it is quite apparent that Leskjopalpus calidus Town, is 

 synonymous. Hence, the genotype of Leskiopalpus, by present 

 designation, is L. depile Coq.

Front at base of antennae produced nearly one-half the eye width, 

 the antennae inserted rather below the middle of the eyes. Frontal bristles 

 descending to the base of the third antennal joint, cruciate from vertex 

 to base of antennae, reclinate from thereon to a point nearly half way 

 down the parafacials. Outside of the frontal row of bristles a parallel 

 row of bristles and scattered bristly black hairs to the eye margins. Para- 

 front als twice as wide anteriorly as at their vertex. Orbital bristles ab- 

 sent, the ocellar bristles strong proclinate. Width of head at the oral 

 margin as great as at the base of antennae; vibrissae cruciate, inserted far 

 above front edge of oral margin, two or three bristles above each. An- 

 tennae descending to the middle of the fare, the second and third joints of 

 equal length, arista bare, the second joint as broad as long. Parafacials
