SUBFAMILY IV. CONOCEPHALIN^E. 535 



I. ORCHELIMUM Serville, 1839, 522. (Gr., "to dance" -f 



"meadow.") 



THE LARGER MEADOW-GRASSHOPPERS. 



Tettigoniids below the medium in size and possessing the 

 characters of the subfamily above noted. They also have the face 

 short, moderately oblique, its dorsal portion prolonged upward 

 at middle to meet the ventral spine of fastigiuni ; pronotum short, 

 usually smooth, more or less saddle-shaped, the metazona pro- 

 longed backward to form a posterior lobe, its hind margin 

 usually broadly rounded; lateral lobes deeper than long, their 

 front margin oblique, lower one usually straight and rounded 

 into the hind one, the latter usually with the adjoining lower por- 

 tion bulging to form what is called the "convex callosity;" hum- 

 eral sinus usually present but varying much in width and depth; 

 tegmiua narrow, usually strongly tapering, the apical width much 

 less than the basal, almost always slightly shorter than wings; 

 stridulatiug organ of male well developed, its veins prominent, 

 the speculum transparent on both tegmina ; front and middle 

 femora subequal in length, unarmed beneath ; hind femora slender 

 but stouter than in Conoccphalus, their under surface either 

 armed with a few short spines or wholly unarmed. Male with 

 apex of supra-anal plate emarginate and usually def lexed ; cerci 

 stout, varying much in form, armed near middle with a single 

 stout tooth ; subgenital plate with apex U-or V-shaped, its styles 

 short one-jointed, set in sockets at the upper outer margins of 

 the concavity. Ovipositor stout, rather broad, its apical half 

 usually distinctly upcurved; when straight or nearly so above, 

 the apical third, except in -militarc, tapering or curved on under 

 side to a fine point. 



This genus is very close to Conoccphaliis (Xiphidiinn) and is, 

 b\ some writers, united with it. Kedteubacher (1891, 494) placed 

 it as a subgenus of Xiphidimii. separating its members from those 

 of A'iphid'uun proper by the same characters as did Serville. The 

 species have a general facies or appearance which enables one 

 after a little experience to separate them at a glance from those 

 of Couoccphahis, but as K. & H. (1915b, 150) have well said, 

 "when the characters of the two are compared, the variation in 

 each leaves us unable to state a single absolute difference." As 

 noted in the key to genera, the larger, heavier body, longer pro- 

 sternal spines, and shorter and broader falcate ovipositor are the 

 chief distinguishing characters of On-hclhniini. The tegmina are
