STETMEOPHYMA, FiisiCh. 



Arcyptera, Serv., Sciidd. ; Mecostathus, Y'leh. {ex parte); Gomphocerus, Burm., 



Borck. 



Head large, gross ; the face somewhat oblique. Vertex obtuse or sub- 

 obtuse; the lateral foveolse triangular or oblong-quadrangular; but these 

 are sometimes indistinct and at others entirely obliterated even in the same 

 species ; frontal costa rather broad. Eyes sub-depressed. Antennae of 

 medium length, filiform. Pronotum flattened above, tricarinate; the median 

 carina somewhat acute, and tlie lateral rather obtuse, sub-parallel, or slightly 

 divergent postei'iorly ; the three transverse furrows undulate, the posterior 

 only cutting the median carina ; the sides marked more or less with im- 

 pressed lines. The prosternum furnished with an obtuse tubercle. Elytra 

 and wings perfect in both sexes, or slightly abbreviated in the female. Legs 

 of the usual structure; the posterior femora moderately dilated. 



This genus includes the Arcyptera of Serville, the name adopted by 

 Scudder; but as that genus depends upon the expansion of the costal borders 

 of the elytra as its chief characteristic, I prefer Fischer's name.

Vertex of the head broad, slightly swollen at the front border of the 

 eyes; apex docked; edge raised to a ridge, with a medial ridge extending over 

 the whole top of the head ; foveolse small, shallow, triangular. Pronotum 

 rugose ; lateral carinae parallel on the anterior half, somewhat divergent be- 

 hind, not so high as the median, and much broken. Elytra long and slender, 

 with no swollen curves; the costal border not so prominent near the base as 

 is usual in this genlis 



Color. — Dark-brown. A narrow, curved, dark line extends from the 

 upper border of the eyes to the lateral carina; of the pronotum, and is the 

 inner limit of a broad, brownish-yellow band, which extends from the eye to 

 the lateral carina", whence it continues backward along the carinas ; below 

 this, upon the upper border of tiie side, extends another broad, black band 

 from the eye to the hind edge of the pronotum ; the median carina is black. 

 The elytra have the costal edge dark, beneath which is a yellow streak ex- 

 tending from the base to the costal border at about two-thirds the distance 

 to the apex ; beneath this is a band, narrow and black at ])ase, broadening
