We here describe a female paratype bearing the same data as the 

 type, excepting the date, which is September 10, 1895, in the United 

 States National Museum. 



Size medium for the genus, form robust; head rather large, full 

 and rounded, about as wide as the pronotum. Maxillary palpi of 

 much the same form as in fasciatus, but with 

 joints not quite as much produced as in that 

 species. Eyes broad-ovate, moderately pro- 

 truding. Pronotum, when compared with 

 that of fasciatus, slightly less transverse, 

 narrowing very slightly cephalad. Tegmina 

 not half as long as caudal femur, apex at 

 humeral angle broadly but distinctly obtuse- 

 angulate, sutural margin passes into distal 

 margin with a distinct angulation, longi- 

 tudinal veins rather conspicuous, cross- 

 veinlets very weak. Wings absent. Supra- 

 anal plate and cerci as in fasciatus. Ovi- 

 positor long, equal to the caudal femur in 

 length, rigid, almost straight, apex similar 

 to that of fasciatus, but armed Avith very 

 sharp teeth.*^ Subgenital plate scoop- 

 shaped, caudal margin arcuato-truncate, briefly cleft mesad.'*^ 

 Caudal femora slightly more robust than in fasciatus.

Figs. 7, 8. — Nemobius maculatus. Ovipositor; normal (Fig. 7) and distorted 

 (Fig. 8). (Greatly magnified.) 



A topotypic male taken October 16, 1904, by Blatchley, and in the 

 Blatchley Collection, affords the additional data given below. 



*i The series of specimens before us show that, when the ovipositor has received 

 usage, these teeth become blunt, and in some cases have been worn down until 

 their bases alone remain. 



^ The degree of truncation and division of the subgenital plate is variable in 

 this species as well as in fasciatus.
