margin of which there is a deep and narrow incision, 
forming a pair of rather long, acute lobes. 
The head is of the third type, that is, the frons is 
strongly tumid, with well-marked transverse depression 
behind; the edge of the occiput is somewhat swollen, the 
sutures not very distinct. 
The pronotum is subpentagonal, a trifle longer than 
broad, and somewhat narrowed posteriorly. The last 
dorsal segment is inflated, but not very strongly, and the 
forceps are simple, contiguous, somewhat depressed, and 
straight, feebly hooked at the tips.

Cylindrogaster rufescens, Burr (nec Kirby), (19008) p. 48. 
This little red Singalese species is fully described, 
figured and discussed by me in (19101). It forms a natural 
group with D. ernesti, Burr, characterised by the emargina- 
tion of the penultimate ventral segment of the male. 
It is this species whose postembryonic development has 
been described by Green under the name Dyscritina 
longisetosa.

This is a large North Indian form, of which the female 
only is known; it resembles D. gerstaeckeri in every 
respect except size, but discovery of the male may show
