34 ^Ir. P. Cameron on new Aculeate [lymenoptera 



Cratolaera, gen. nov. 



Ocelli distorted. Front raised near tlie eyes. First cubital 

 cellule above ninch longer than the second. I^Iedian segment 

 as long as the pro- and mesothorax 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 u|^per 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 tlie apex. The first transverse 

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

 is large, oblique ; both the recurrent nervnres are received 

 behind th(; 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, 

 rai.-ed, distinctly defined tubercle on the apex ; this part is 

 narrowed towards the apex of the segment laterally. Tlie 

 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 wirliin the eye-margins separates 

 this genus from Tuchyies and Tachysphex ; from Larra and 

 Notogonia 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 Tachysphex^ 

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