 of male very stout and bullate on basal half or more; abdomen of 

 female bluntly rounded apically, the posterior segments much abbre- 

 viated ; ovipositor but slight] yexserted. . 27. Oedaleonotus (p. 390). 

 j*. Relatively slender-bodied; dorsal disk of prozona not tumid 

 independently of the metazona; pronotum truncate posteriorly; 

 portion of metasternum lying behind the lobes laterally abbre-

Body exceptionally long and slender, subcylindrical, a little com- 

 pressed. Head excepting eyes scarcely enlarged, the face considerably 

 declivent; vertex scarcely (male) or somewhat (female) tumid, trian- 

 gular, the eyes approximate, especially in the male where the slender 

 fastigium between them is narrowly sulcate; fastigium declivent, 

 expanding greatly in front and broadly berfTowed; frontal costa of 

 moderate width but distinctly broader thanHhe interspace between the 

 eyes, subequal but constricted just below the ocellus, percurrent, sul- 

 cate; eyes large, prominent, particularly in the male where they are 

 subrotund, while in the female they are nearly half as long again as 

 broad, in both sexes but particularly in the male about twice as long 

 as the anterior infraocular portion of the genae ; antennae rather slender, 

 cylindrical, much longer than the head and pronotum together. Pro- 

 notum compressed cylindrical, truncate at each extremity, with com 

 pletely parallel sides and with a slight uniform median carina, the 

 prozona quadrate above and fully three times as long as the metazona, 

 its two median sulci slightly impressed, subapproximate, and distant 

 from either margin ; lateral carinae wholly absent, the lateral lobes very 

 short, their lower margin obtusely angulate, the posterior angle distinct 

 but obtuse. Prosternal spine rather slight and moderately slender, 

 conical, erect; mesosternal lobes subattingent in both sexes or even 

 attingent in the male; metasternal lobes attingert in both sexes. 

 Apterous. Fore and middle femora scarcely more gibbous in the male 

 thsfn in the female; hind femora very slender, unarmed; hind tibiae 

 with short spines, similar in length on either side, 8-9 in number in the
