Sept. 1896.] Scudder: North American Nemobius. 105 



as broad again as long, more or less mottled with testaceous at the humeral angle. 

 Tegmina as long as the abdomen, well rounded apically, fusco-fuliginous, more pallid 

 along the union of the lateral and dorsal fields, the lormer in the J tapering through- 

 out ; wings twice as long. Legs fusco testaceous or fuscous. Ovipositor about as 

 long as the head and pronotum together, straight, not very slender, the apical blades 

 a little enlarged basally, tapering regularly to a point, almost as long as the stem, 

 bluntly, feebly and minutely serrulate. Length of body, <?,7.5 mm., 9i7 nim.; of 

 hind femora, $ , 6 mm., 9 , 5.5 mm.; of ovipositor, 2.6 mm. 



I (?,2 9. Trinidad (Uhler). This species must be nearly allied 

 to N. longipennis Sauss., which I know only from description, but has 

 a shorter and straighter ovipositor. 



Nemobius aterrimus, sp. nov. 



Head not very large, moderately full, black, more or less striped with castaneous 

 above, posteriorly ; eyes not very prominent ; antennae fusco-luteous ; maxillary palpi 

 fusco-luteous, the last joint infuscated except at base. Pronotum faintly tapering an- 

 teriorly, less than half as broad again as long, black, provided scantily with long, 

 curved, black bistles. Tegmina black or blackish fuliginous, a little shorter than 

 the abdomen, in the 9 truncate ajncally; wings wanting. Legs dark fusco-testaceous. 

 Ovipositor distinctly longer than head and pronotum together, but very much shorter 

 than the hind femora, distinctly arcuate, the apical blades broadened basally, regu- 

 larly tapering to a fine point, very minutely and closely serratulate. Length of body, 

 $ , 9 mm., 9 , 6.5 mm.; of hind femora, $ , 6.25 mm., 9 , 5.5 mm.; of ovipositor 3 mm.

The doubtful reference by Bruner (Publ. Nebr. Acad. Sci., Ill, 

 32) to this species as coming from Nebraska is perhaps incorrect, but 

 I do not know to what species the reference belongs. 



There is some variation (at least in the United States) in the fine- 

 ness of the serration of the blades of the ovipositor in this species. It 

 is almost invariably long winged, but I have three females which are ap- 

 parently apterous, though with long tegmina, one from Ogle Co., 111. 

 (Allen), the second from Chicago, 111., the last from Florida. These 

 first two localities are far north of any other known to me, excepting a 

 single $ from Norway, Me. (Smith) in the Museum of Comparative 

 Zoology (^possibly wrongly labelled as to locality). Other specimens I 

 have seen come from Georgia (Morrison), different places in Florida, 

 such as Lake Worth and Charlotte Harbor (Mrs. Slosson), Sandford 

 (Frazer), Capron (Comstock), and Indian River (Priddey-L. Bruner), 

 Texas (Belfrage), Carrizo Springs, Tex. (Wadgymar-L. Bruner), Cuba
