Meriniria belfragei, Stdl, 1873. Recen. Orth., I, 102. 



Mermiria belfragei, Thos. , 1875. Rept. Geog. and Geol. Surv. W.

Mermiria belfragei. Scud., 1877. Cent. Orth., 47. 



Hab. The eastern slopes of the Rocky Mountains from Wyoming 

 to New Mexico and eastward to Georgia. 



The National Museum contains a specimen which seems to be the 

 type. Except M. Im'ittata it is the most widely distributed species of 

 the genus. It seems to be partial to regions where vegetation is sparse.

The National Museum contains a male and female from the last men- 

 tioned locality.

Post. Fern i S mm 



Vertex triangular, as long as (female) or longer than (male) wide 

 with the sides straight and meeting at a very acute angle which is bare- 

 ly blunt at the tip. The median carina of the vertex is entirely want- 

 ing and the sides are somewhat expanded and a little ascending. The 

 frontal costa is deeply sulcate throughout in the male and in the fe- 

 male above the ocellus ; below it ends suddenly half-way between the 

 ocellus and the clypeus. The face is very decidedly sinuate. The 

 lateral foveolse are quite distinct, elongate triangular and curved. The 

 pronotum is scarcely (female) or not longer than the head. The me- 

 dian carina is less distinct than in alacris and the lateral carin^e are 

 very faint. The transverse sulci are scarcely distinguishable and the 

 metazone is scarcely perceptibly punctate. The lower margin of the 

 lateral lobes of the pronotum is straight or perceptibly sinuate. The 

 usual postocular band has at its lower border a very faint carina (in 

 this respect it resembles alacris and bivittata). The colors are green 

 and ferruginous or purplish-brown, the dark color being more decided 

 in the male. In this sex the face is completely infuscated and the top 

 of the head is occupied by a very broad band which is three times as
