obliquely upward from the lower level of the eye toward the upper pos- 

 terior limit of the lateral lobes of the prozona, usually narrowing as it 

 goes. 



29. PHILOCLEON, new genus. 



(3>iXoKh.Gov, a character in Aristophanes "Wasps," who ends the play in a leaping 



dance. 1 ) 



Body closely resembling that of Podisma, compressed cylindrical, 

 not very slender, rather thinly pilose throughout with rather long deli- 

 cate hairs. Head moderately large, feebly prominent, 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 convex (male), not 

 more than half as long again as broad, produced neither above nor 

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

 the head and pronotum together. Pronotum short, compressed cylin- 

 drical, with no trace of lateral cariuae and 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, conical; 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 metasthethiuin; inter- 

 space between the mesostemal 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). Tegmiua 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 first 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 arapliate at the base; cerci lamellate, narrow beyond the 

 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 Pezotettix nigrovittatus Stal.
