PSEI.APHIDAE. 505 



the head and thorax, basal joint stout and rather short, joints 3 and 6, 

 usually 4 also, smaller than the contiguous ones, the terminal three, or five, 

 evidently more expanded than their predecessors. 



This genus will include Section XVI of Sagola, comprising *S'. gracilis 

 (2473), S. crassicornis (3372), and S. connafa (3374). This last species, 

 owing to the connate antennal tubercles, may be considered aberrant. 



4019. Stenosagola planiocula sp. nov. 



Nitid, finely but not closel}?' punctate ; castaneo-rufous, antennae paler, 

 legs testaceous, tarsi and palpi yellow ; pubescence yellowish, elongate 

 and subdepressed, longer and more erect on the hind-body. 



Head rather longer than broad, obcordate, gradually narrowed anteriorly, 

 with obtuse hind angles ; frontal channel extending as far back as the eyes, 

 deep and moderately broad, a little narrower between the distinctly 

 separated and elevated antennal tubercles ; occipital foveae quite free and 

 punctiform. Eyes flat. Thorax oviform, fully a third longer than broad, 

 widest near the middle ; lateral foveae deep, not reaching the middle, the 

 median one moderately large, subquadrate, basal punctures minute or 

 obsolete. Elytra subquadrate, shorter and hardly any broader than thorax, 

 slightly narrowed towards the base ; sutural striae rather broad and deep 

 at the base, the dorsal short and subpunctiform. Hind-body quite double 

 the length of elytra, rather wider behind than they are, basal three seg- 

 ments successively increase, fourth paler and slightly shorter than third, 

 fifth retracted. 



Legs moderately stout in proportion to the bulk of the insect ; tibiae 

 somewhat expanded and arched outwardly below the middle, the posterior 

 obliquely narrowed externally near the extremity. 



Antennae shorter than the head and thorax ; basal joint not double 

 the length of the subrotundate, thick second, the next very small, fourth 

 slightly larger but not as large as the fifth ; sixth smaller than seventh, 

 both transverse, eighth distinctly broader than seventh but not as broad 

 as the transverse ninth or tenth, eleventh subquadrate, rounded at the 

 extremity, not as long as the preceding two combined. 



Head, underneath, with a transverse furrow before the eyes and a central 

 fovea at its base. Abdomen elongate, first segment short and partly covered 

 by the femora, 2-4 increase, fifth nearly as large as fourth ; sixth and seventh 

 retracted, the latter broad biit very short.

 1914. 



4020. Stenosagola oblongiceps sp. nov. 



This rather smaller species resembles S. planiocula but differs as follows : — 



Eyes more distinct and slightly convex. Head oblong, its sides straight 

 behind the eyes, with nearly rectangular hind angles. Thorax slightly 

 shorter, its median fovea not as deep and angular. Antennae shorter, 

 fourth joint nearly as large as fifth, sixth distinctly smaller than contiguous 

 ones, seventh and eighth transverse but not as broad as the following ones. 

 Basal ventral segment quite visible, sixth obtusely triangular, its operculum 

 oblong.
