 pygidiuin densely scaly, underside closely and not coarsely ])unctured ; femora

 widened from the base to the apex, outer a])ical angle rounded, tarsi narrow, 

 first two joints elongate, third short, not bilobed, fourth as long as the two pre-

A female specimen with the above locality label in the Nat. ]\Ius. 

 collection. 



Subtribe Phijtobii. 



Thi.-< .subtribe contains tho.se fjenera in which the ])ect()ral canal is 

 either entirely ab.sent or, if present, becomes effaced between the 

 anterior coxne. The beak is short and stout, rarely Cce log aster, Phy- 

 toblusj more elongate. The eyes are not concealed in repose, and 

 the prothoracic lobes are obsolete (except Ccelogaster). The species 

 are all stout, robust insects, rarely elongate (Perenihes). 



According to the formation of the beak and the presence or ab- 

 sence of prothoracic lobes, I have arranged the genera under two 

 groups : 



Beak elongate, less robust: scrobes parallel, directed against the eyes; eyes com- 

 jili'tely concealed in repose by prominent prothoracic lobes; claws bifid. PI. 

 xiv, fig. '.i'.in Grou]> I. Phytobii spurii. 



Beak short, .stout, scrobes oblitjue. directed beneath the eyes; eyes entirely or 

 partially free, postocular lobes of jirothorax feeble or obsolete. PI. xiv, fig. 37. 



(Jrouj) II. Phytobii veri. 



Group I. Phytobii spurii. 

 Aside from the characters given above nothing more need be said 

 in the definition of this group, which is represented by the single 

 genus Cielogader. 



C/E LOG ASTER Schoen. 



Heak moderately stout, as long as ( ^ ) or a little longer ( 9 ) than 

 the prothorax, cylindrical, curved, somewhat widened at the apex 

 in the female, scrobes parallel, expanded towards the eyes, antennae 

 slender, inserted two-titths from the apex ( £ ) or at the middle ( 9 ), 

 funicle 6-jointed, joints 1-3 elongate, the first stouter, outer three 

 joints short, gradually wider and merging into the elongate elliptical 

 clava. Eyes rounded, convex, with acutely elevated orbital ridges 

 completely concealed in repose ; prothorax wider than long, nar- 

 rowed in front, ocular lobes prominent, anterior margin emarginate,
