34 Mr. P. Cameron on new Aculeate Hymenoptera 



Cratolarra, gen. nov. 



Ocelli distorted. Front raised near the eyes. First cubital 

 cellule above much longer than the second. Median segment 

 as long as the pro- and niesothorax united. Anterior tibiae 

 without spines ; the tarsi with long spines. Pygidium 

 strongly punctured, the punctures mostly in longitudinal 

 rows, only sparsely pilose. 



Eyes large, converging above ; the upper part with a dis- 

 tinct inward curve ; distinctly margined above and behind. 

 Mandibles large, bearing a large tooth near the base beneath ; 

 the apex with one tooth. The top of the pronotum reaching 

 to the top of the mesonotum. All the tarsi and the four 

 posterior tibiae are strongly spinose ; the anterior femora 

 dilated, narrowed towards the apex. The first transverse 

 cubital nervure is straight, oblique ; the apex of the radius 

 is large, oblique; both the recurrent nervures are received 

 behind the middle. The second antennal joint is large, 

 smooth, and shining. The apex of the median segment has 

 an oblique slope. Abdomen longer than the head and 

 thorax united ; the basal ventral segment has a large, 

 raised, distinctly defined tubercle on the apex ; this part is 

 narrowed towards the apex of the segment laterally. The 

 pygidial area is sharply keeled laterally ; the sides inside the 

 keel are depressed ; there is a distinct, wide, deep furrow 

 down the middle; the sides of the segment are broad ; the 

 lower and upper edges clearly defined, the middle hollowed. 



The presence of the fold within the eye-margins separates 

 this genus from Tachytes and Tachysjihex ; from Larra and 

 Nofogonia it may be separated by the strongly punctured 

 pygidium, and by the first cubital cellule being longer than 

 the second. In the latter respect it agrees with J'achyspheXj 

 but that genus, inter alia, wants the folds near the eyes. 



Cratolarra femorata, sp. n. 



Nigra ; femoribus posticis rufis ; capite laevi ; thoraco dense albo 



piloso ; alls fusco-violaceis. $ . 

 Long. 14 mm. 



Hah. Khasia. Coll. Eothney. 



Scape of antennae smooth, shining, bare ; the second joint 

 shining, almost bare; the others thickly covered with short 

 pale pubescence. Head smooth and shining, above almost 

 bare ; the face and clypeus thickly covered with white 

 pubescence. Mandibles behind the apex and the middle of 

 the basal tooth rufous ; palpi fuscous black, thickly covered
