252 THE ENTOMOLOGIST. 



ceous colour ; the apex of femora, tibise aud tarsi black ; flagellum of 

 auteuna3 dark testaceous ; the wings hyaline ; the nervures and stigma 

 black. S . Length, 7 mm. 



Haundraw Valley, Middle Tenasserim. August (C. T. 

 Bingham). 



Antennae stout, slightly longer than the body, 26-jointed, tapering 

 towards the apex ; the scape below densely covered with long white 

 pubescence ; the flagellum densely with a short stiff fuscous pile ; the 

 third joint a little shorter than the fourth. Face closely, distinctly 

 punctured ; the clypeus distinctly, but more widely punctured ; they 

 are, as are also the cheeks, densely covered with longish white pube- 

 scence. Mesonotum closely, somewhat strongly punctured, densely 

 covered with white pubescence ; the apex smooth. Scutellum de- 

 pressed, rugosely reticulated above ; the apex roundly incised, largely 

 projecting over the post-scutellum ; the lower part bordered, and with 

 a stout keel down the middle. Base of metanotum with three are^e, 

 the central narrow, of equal width ; the large lateral obliquely narrowed 

 from the outer to the inner side ; the tooth-bearing part depressed, 

 margined and bearing a few irregular longitudinal striae ; the narrowed 

 apex closely, transversely rugose; the apical slope transversely, closely 

 reticulated. PropleuraB finely punctured ; the centre below stoutly 

 striated ; there is a broad punctured band round the top and base of 

 the mesopleuras, the rest smooth and shining; the mesosternuni is 

 more strongly punctured. Metapleurse at the base above closely, 

 somewhat rugosely punctured, the rest closely, strongly reticulated. 

 First abdominal segment rugosely punctured in the middle, the sides 

 stoutly, irregularly, longitudinally striated ; the second is strongly, 

 longitudinally, rugosely punctured ; the third more finely ; its apex 

 roundly incised. 



There are two known species of Rothneyia, both described 

 from females. When describing the genus (Manchr. Mem. xli. 

 (1897), No. 4, p. 19) I suggested that it should form the type of 

 a new tribe — Eothneyini. I am still of that opinion. An 

 examination of the species here described, as well as of my 

 genus Acanthoprymnus, enables me to correctly locate the genus. 

 It will form a tribe of the Cryptinse, near Phygadeuonini. 

 In the species here described there are clear indications of 

 parapsidal furrows at the base of the mesonotum, and there is 

 a still more distinct, deep mesosternal furrow. The areolated 

 metanotum is also not unlike what we find in that tribe ; on it 

 the spiracles are roundish. The transverse median nervure is 

 received shortly behind the transverse basal ; the disco-cubital 

 nervure is unbroken ; the areolet has the apical nervure distinct 

 but bullated ; the discoidal cellule is closed at the apex ; the 

 transverse median nervure in hind wings is broken below the 

 middle. Clypeus not separated from the face ; its apex broadly 

 rounded. Mandibles broad, bidentate. In the male, of the 

 three dorsal abdominal segments, the third (apical) is the 

 largest ; in the male there are seven ventral segments.
