{^iXoKXaoor, a character in Aristoj uane.s "Wasps,'' w}u> ends the phiy in a leaping 



dance.') 



Body closely resembling that of Podisma, compressed cylindrical, 

 not very slender, rather thinly i)ilose throughout with rather long deli- 

 cate hairs. Head moderately large, feebly i>rominent, the genae not 

 tumescent, the vertex well arched but only slightly elevated above the 

 pronotum; fastigium sulcate and declivent, passing insensibly into the 

 straight and little prominent frontal costa, the face retreating but little; 

 eyes rather widely separated, moderate in size, rather prominent, broad 

 oval, the front margin subtruncate (female) or feebly con^' x (male), not 

 more than half as long again as broad, produced nei' ler above nor 

 below; antennae slender, much longer than (male) or as long as (female) 

 the head and pronotum together. T? notum short, compressed cylin- 

 drical, with no trace of lateral carinae *. 1 very feeble median carina, 

 both front and hind margins truncate; prozona sparsely and feebly, 

 metazona more closely but not densely punctate, the transverse sulci 

 moderate. Prosternal spine short, corical; meso- and metastethia 

 together much longer than broad in both sexes, the latter narrowing 

 rapidly behind, so that the portion behind the lobes is only (male) or 

 scarcely more than (female) half as broad as the metasthethium; inter- 

 space between the mesosternal lobes longer than broad (male) or sub- 

 quadrate (female), the metasternal lobes attingent or subattingeut 

 {male) or approximate, the interspace narrower than the frontal costa 

 {female). Tegmina wanting. Hind femora moderately stout, the 

 inferior genicular lobe pallid except at extreme base, the hind tibiae with 

 nine to eleven spines in the outer series. Sides of the ttrst abdominal 

 segment with no tympanum, the extremity in the male clavate, the sub- 

 genital plate with no apical tubercle, its lateral margins abruptly and 

 considerably ampliate at the base; cerci lamellate, narrow beyond th«' 

 rather broad base and incurved. Abdomen of female regularly taper- 

 ing, the ovipositor normally exserted. 



The genus is represented by a single Mexican species, originally 

 described as Pe^o/e<<<> HiV/ror/Z^rt tMA' Stdl.
