Nf>w gener.i and species of hymenoptoi'.i from^India. 303 



iuto reticulations aud striations ; the metapleurae strongly and 

 closely punctured ; the oblique furrow at the base is deep. 

 The 4 auterior legs are fulvons, their coxae aud troohanters 

 yellowish-white; the coxae, the apices of the feniora broadly 

 and the base of the inetatarsus uarrowly, black; the hiuder 

 spurs blackish. Abdomen black, the segments jellowish la- 

 terally on the apex; the yellow band on the pétiole is larger 

 aud more triangulär; the 2i'(l aiid foUowing segments are clo- 

 sely punctnred ; the gastrocoeli shallow, the apex shagreened, 

 the base triaugularly raised. 



VI. Piniplini. 



Coleoccntriifi Mölleri Binghain» 



This species appears to me to be a Rhyssa, It does not 

 seem to hâve, judging i'rom the figures, the characteristics of 

 the Acoe.nitini^ the tribe to which ColeocentriùS belongs. The 

 abdomen of C. Mölleri is ideutical with that of Rhyssa aud 

 the Finipliîii, aud does not hâve the large plough-share-shaped 

 hypopygium of the Acoenitini. It, moreover, has the trans- 

 versely striated niesouotum of Rinjssa. Cf. Biugham, Jouru.

16. Tricbopimpla, gen. noT. 



Head and thorax deusely bairy. Clavps pectinated. Me- 

 dian segment without a keel and depressed in the middle at 

 the base. Clypeus rouudly couvex; its apex depressed, rounded. 

 Areolet narrowed at the top, the nervures nnitmg there; the 

 trausverse median nervure is received distinct ly in front of 

 the trausverse basai ; there is no stump of a nerve on the 

 disco-cubital; in the hind wings the transverse median ner- 

 vure is broken in the middle. Legs moderate in leugth; the 

 fore tibiae atteuuated at the base. The 2»<i and foUowing 

 segments of the abdomen are smooth impunctate and without 

 latéral or oblique dépressions. Ovipositor projecting; the hy- 

 popygium cultriform, broad at the base. The temples are not 

 broad, the occiput is margiued ; the malar space is moderate; 

 the maudibles broad, bidentate at the apex. AU the abdo- 

 minal segments are longer than broad; the 3rcl joint of the 

 antennae is nearly twice the length of the 4tli. 



The cultriform, prominent ventral valve would refer this 

 genus to the Acoenitini, but the legs are not longish, nor the 

 temora stout as in that group; tiie legs in fact are, if any 

 thiug, shorter, and certain ly more slenderly built, than in most 

 species of Fmpla, from which it further differs in the corn-
