eonsistins of a pair of distant slight denticnlatioiis, lying well outside 

 the basi' of the submediaii ridges of the supiaaiial i>late; cerci broad 

 at base, rapidly tapering to the middle, where they are about half as 

 broad as at base, beyond again expanding wholly by the triangulai 

 producticui of the inferior apical portion, the apical margin truncate, 

 the whole about two and a half times the basal breadth, feebly incurved : 

 subgenital plate about as broad as long, the apical nuirgin slightly 

 elevated above the lateral, the two together, as seen from above, well 

 rounded, entire.

Pezotetlix riola Blatchley 1, Can. Ent., XXIII (1891), p. 81. 



Of moderately large size, cinereofuscous with an olivaceous tinge. 

 Head somewhat x>rominent, olivaceo testaceous variably but generally 

 considerably infuscated, above dark fuscous, separated by a testaceous 

 stripe from the broad ])iceous postocular band: vertex gently tumid, 

 feebly elevated above the pronotum, the interspace between the eyes 

 half as broad again (male) or twice as broad (female) as the first antennal 

 joint; fastigium somewhat steepl}^ declivent, plane, with the lateral 

 margins faintly raised in the male; frontal costa fading belbre the clyp 

 eus, equal or subecjual, as wide as the interspace between the eyes, 

 sulcate at and below the ocellus, at least in the male, somewhat densely 

 jmuctate throughout; eyes moderately large and prominent, very much 

 longer than the infraocular portion of the genae; antennae rufo-testa- 

 ceous, scarcely shorter than (male), or nearly tvYO-thirds as long as 

 (female) the hind femora. Pronotum subequal, feebly enlarging (at least 

 below) on the metazona, the sides with a broad piceous postocular band 

 confined to the prozona in the male, the same being wholly obsolete, 

 obscure, or confined to the upper limits of the lateral lobes in the female; 

 disk very broadly convex, passing by a distinct but blunt angulation 

 forming feeble lateral carinae into the inferiorly vertical lateral lobes; 

 median carinji distinct but not very sharp on the metazona, subobso 

 lete or obsolete, especially between the sulci and, in the male, on the 

 prozona; front margin truncate, hind margin obtusangulate, the angle
