340 Ml!. R. E. TURNER ON THE [Feb. 15, 



Length 6 mm. 



Hab. Shwegyin, Tenasserim {Bingham) ; Mackay, Queensland 

 (Turner). 1 <$ , 4 9 . 



Australian specimens differ in having the third abscissa of the 

 radius almost if not quite as long as the second, but not otherwise. 



This species is noticed In the 'Zoological Record' for 1903 as 

 Cerceris ligea. 



Ceropales tenuatus, sp. n. (Plate XXXII. fig. 10, $ .) 



$ . Clypeus subtriaugular, a little broader than long, broadly 

 truncate at the apex, the labrum exposed and broadly rounded at 

 the apex. Eyes converging towards the clypeus, broadly but 

 very shallowly emarginate ; posterior ocelli rather less than twice 

 as far from the eyes as from each other. Antennae stout, the 

 apical joints feebly arcuate beneath ; the front not raised into a 

 prominence between the antenna?. Pronotum short, the anterior 

 margin straight, not rounded at the angles, the posterior margin 

 scarcely arched ; mesonotum with two distinct longitudinal 

 furrows. Median segment rounded at the sides, rather steeply 

 sloped, broader than long, with an obscure median sulcus. 

 Abdomen nearly as long as the head, thorax, and median segment 

 combined, very sti-ongly compressed laterally. Legs unarmed, 

 not unusually long. Head opaque, sparsely punctured; thorax 

 shining, almost smooth ; median segment very finely transversely 

 striated ; abdomen smooth, slightly shining. Second abscissa of 

 the radius less than half as long as the third. 



Black ; labrum, clypeus, front as high as the base of the 

 antennae, scape, margins of the eyes broadly interrupted on the 

 summit, prothorax, sternum, a broad band on the mesonotum 

 from before the middle to the posterior margin, a narrow band 

 above the teguke, pleurae, scutellum (except on the sides and 

 extreme apex), postcutellum, median segment (except a large black 

 spot on each side at the base), and the femora beneath yellow ; 

 first and second abdominal segments, the base of the third, and 

 the legs (except the posterior tarsi) light testaceous brown. Wings 

 hyaline, iridescent, nervures fuscous, stigma testaceous brown. 



Length 12 mm.

Fam. Sphegidj;. 



Genus Paracrabro Turn. 



Paracrabro Turn. Ann. & Mag. Nat. Hist. (7) xix. p. 274 



(1907). 

 This genus is perhaps nearest to Stigmus, but also shows points 

 of affinity to Pemphredon. 



Type of genus, P.froggatti Turn. (Plate XXXII. fig. 11, $ .)
