83. GENUS OPHIDERMA Fairmaire 



Ophiderma Fairmaire, Rev. Memb. 493 (1946). 



Characters : Medium sized, elongate forms with the pronotum regularly and roundly convex, 

 not compressed, the posterior apex of the pronotum extending to a point about half way between the 

 internal angles and the tips of the tegmina which are largely exposed. Head subquadrate, twice as 

 broad as high; base weakly sinuate ; apex obtusely triangular; eyes subovate; ocelli large, about 

 equidistant from each other and from the eyes and situated somewhat below a line drawn through 

 centers of eyes: inferior margins of genje sinuate; clypeus extending for half its length below inferior 

 margins of genae, tip blunt. Pronotum moderately convex, not laterally compressed, regularly rounded ; 

 metopidium sloping, much wider than high ; humeral angles weak, blunt and rounded; median carina 

 faintly percurrent; sides of pronotum sometinies weakly impressed, usually punctate and pubescent 

 but never ridged ; posterior apex acute and reaching to a point about half way between internal angles 

 and tips of tegmina. Tegmina well exposed, only the clavus and a small portion of the corium covered 

 by the overhanging sides of the pronotum; corium with three strong longitudinal veins, the two inner 

 ones connected by a cross-vein as in the Cyrtolobus group; five apical and two discoidal cells; median 

 apical cell petiolate ; apical limbus broad. Legs simple; hind tarsi a little longer than the others. 



Type salamaiidra Faimaire. 



Geographical distribution : This genus is particularly abundant in the United States but is 

 represented also in Canada, Mexico and Central America with one species described from South 

 America. The center of population seems to be the United States. As in the preceding genus, we 

 have indicated general areas except for those species which are known only from a single state, and, 

 as in former designations, the term « United States » indicates that the species has been reported 

 from most of the larger faunal areas of the country.
