132 FAMILY Y.— TRYXALIN^. 



GENUS Eremnus McNeill (1897). 



Vertex somewhat declivent, broader than the frontal 

 costa at the clypeus, snlcate, without a median carina, 

 bounded by straight, sharp but slight caringe, which meet at 

 the front at an angle greater or less than a right angle. The 

 lateral foveolee are sub-quadrate, about twice as long as 

 broad, very distinct and very apparent from above. The 

 frontal costa is about half as wide at the vertex as at the 

 clypeus, slightly sulcate with low broad carina along the 

 sides. Seen from the side the face is moderately arcuate and 

 moderately oblique. The antennae are filiform, a little 

 (female) or considerable (male) longer than the head and 

 pronotum. The median carina of the pronotum is quite 

 distinct and cut once behind the middle of the principal sul- 

 cus. The lateral carinee are very strongly sinuate and the 

 posterior margin of the metazone is roundly and very ob- 

 tusely angulate. The lateral lobes of the pronotum are 

 higher than long with the anterior and the posterior mar- 

 gins nearly straight and vertical. The mesosternal lobes 

 are separated b\^ a space several times as wide as long in 

 both sexes. The metasternal lobes are separated by a space 

 a little longer than wide in male and female. The tegmina 

 and wings are well developed, not quite ecj[ualing or some- 

 what longer than the abdomen. The former have the scapu- 

 lar area transparent and filled with a single series of oblique 

 cross-veins. The discoidal and the uhiar areas have each a 

 false vein with a single row of cells on either side. The 

 posterior femora have three usually well marked sub-tri- 

 angular or irregular brown spots on the upper face. The 

 posterior tibige are red or yellowish with the spurs on the 

 inner side much elongated and very unequal. The ovipositor 

 is very slightlv exerted, only the extreme tip being visible. 



Eremuus {Aulocarfi) Scudderi Bruner. 



General color dull brown, in some specimens inclining to 

 ferruginous, the tegmina usually very heavily and evenly
