certain lights, robust, shining ; the head somewhat sparsely punctate, frontal channel 

 angulate posteriorly ; the thorax evenly arched from the anterior angle to the base, 

 distinctly marginate at the sides, with the edges very evenly and finely crenulate, 

 surface sculpture not very close, disc convex ; the scutellum uneven, transverse 

 in front, somewhat sharply acuminate behind ; the elytra wholly sculptured above, 

 deeply and widely impressed in the middle close to the base, before the apex is 

 a white pubescent fascia with the posterior edge almost straight, and a second 

 undulating band well behind the middle, apices strongly 4-spinose ; the legs and 

 antennae cyaneous. 



This species is the fourth in the genus recorded from the Japanese 

 Archipelago, it is similar to G. 4<-undulafus, Motsch., in its elytral 

 spines, but the large size, colour, and shape of the thorax and scutellum 

 are very different. 



Sab. : Japan {Fenton). Also an example in the British Museum 

 from the Huikiu Islands, probably Oshima. 



Note. — Corcdhus 4i-undulatus, Motsch., is brassy or brassy-green 

 in colour, or very rarely purple-black, and it usually measures 7-8 

 mm. The thorax also is rather widened out behind, and the scutellum, 

 although bulging out somewhat before the base, is more triangular, 

 and in fresh specimens there are four patches of pubescence, which 

 represent a median fascia.

 BY J. W. SHIPP. 



EXOCHL^NUS. 



Closely allied to Leucospis, but the abdomen is short, stouter, and with the first 

 or basal segment nearly as wide as thorax. Face rather more elongate from the 

 lower margins of the eyes. Head narrower laterally. Antennae ll-jointed, scape as 

 long as the three following joints ; 2nd joint short, not so thick at base as at apex ; 

 3rd joint as long again as 2nd, narrow, wider at apex ; the rest gradually thickening 

 to the apex, and of equal length. Apex of anterior tibiae armed with a curved 

 spine. Anterior coxae very elongate and almost as long as femora, the tibia not so 

 long as the femur. Metathorax short, stout, and as wide as pronotum, with the 

 posterior angles slightly rounded. Abdomen as long as thorax, with the posterior 

 segments very much compressed. Apex of ovipositor flattened laterally at ex- 

 tremity. Intermediate tibiae with a small tooth at apex. Posterior coxae much 

 dilated on the upper margin, with the apical angle rounded. Hind femora with one 

 large tooth near the base, followed by seven smaller points ; hind tibiae curved, 

 produced to a tooth and armed with a small spine at apex j tarsi furnished with a 

 number of spines at margins.
