 sparsely beset with black bristles of no great length, fuscous, with a more or 'ess dis- 

 tinct, sometimes very distinct, testaceous, humeral stripe. Tegmina of $ shorter 

 than the abdomen, very pale testaceous, strongly infumated at base, the lateral 

 field with a piceous stripe ; of J covering a little more than half of the abdomen, 

 very broadly rounded or subtruncate apically, testaceous with the lateral piceous 

 stripe of the $ and a basal dorsal piceous spot. Legs fusco-testaceous. Ovipositor 

 scarcely as long as the hind femora, straight or very faintly arcuate, the apical blades 

 scarcely enlarged at the base, slender and tapering regularly to a fine point, with 

 open serration. Length of body, $ , 7.5 mm., J , 8 mm. ; of hind femora, $ , 6.6

 Valley, Utah, Aug. 1-4; an immature $ was also taken at same date. 



This is a smaller species than N'. fasciatus, with relatively shorter 

 ovipositor. 



Nemobius ambitiosus. 



Nemobius ainbitiosus ScuDDER ! Proc. Bost. Soc. Nat. Hist, XIX, 81 ( 1871). 



This species is only known in brachypterous form and is probably 

 never macropterous. It has been found only in Florida, at Ft. Reed 

 (Comstock), Charlotte Harbor (Mrs. Slosson), Sandford (Frazer), 

 Indian River (Priddy), and Jacksonville (Ashmead). The last two 

 localities are derived from Bruner's collection. 



Nemobius neomexicanus, sp. nov. 



Head rather tumid, fusco.:s or fusco-castaneous, paler below; eyes rather 

 small, not very prominent ; antennae dull luteous, maxillary palpi luteous, the last 

 joint infuscated only at extreme tip. Pronotum tapering slightly forwards, less than 

 half as broad again as long, sparingly beset with long black bristles, testaceous or 

 fusco-testaceous. Tegmina of both sexes as long as the abdomen, infuaiiated except 

 along the sides of the dorsal surface and the costal margin, which are pallid, apically 

 strongly rounded, the lateral field in the 9 subequal basally, tapering only on the 

 apical third ; wings twice as long. Legs luteo-testaceous, the hind femora a little 

 infuscated. Cerci slender, hardly so long as the pronotum and tegmina together. 

 Ovipositor about as long as head and pronotum together, straight, the apical blades 

 not basally enlarged, tapering regularly to a point, above sharply, rather strongly, 

 and rather distantly denticulate. Length of body, $ , 7 mm., 9 , 7.25 mm.; of hind 

 femora, $, 4.5 mm., 9> 5 nim.; of ovipositor, 3 mm.
