the more convex lateral pronotal margins, spotted conuexivum, 

 &c. ; from M. conrexus, Montand., it is distinguished by the 

 head between the eyes being broader than long. 



Thurselinus, gen. nov. 



Body ovate, moderately convex ; head very large, almost as long 

 as pronotum, rather more than one-third broader between eyes than 

 long ; eyes elongate, much narrowed, and slightly converging ante- 

 riorly ; labrum rounded, reaching base of second joint of rostrum; 

 pronotum scarcely broader than base of hemelytra, only slightly nar- 

 rowed anteriorly, its anterior angles not reaching the middle of eyes ; 

 scutellum short, about twice as broad at base as long ; hemelytra 

 complete ; mesonotum medially carinately longitudinally elevated ; 

 anterior femora ampliated, inwardly notched towards base. 



Differs from Macrocoris by the much larger and broader head ; 

 anterior angles of pronotum not reaching the middle of eyes ; 

 shorter and broader scutellum, &c. 



Thurselinus greeni, sp. n. 



Ochraceous ; scutellum brownish ochraceous ; eyes black ; basal 

 area of pronotum with some longitudinal piceous lines ; body beneath 

 and legs uniformly ochraceous ; membrane clouded with pale fuscous ; 

 head almost as long as pronotum, its anterior margin convex, with a 

 somewhat flattened central basal space ; pronotum transversely striate 

 near anterior margin, very finely and obscurely punctate, the lateral 

 margins slightly rounded, a little narrowed anteriorly, but almost sub- 

 parallel ; scutellum very finely granulose, broadly subtriangular ; con- 

 nexivum piceous at segmental incisures. Long. Gmillim.

Odynerus camicrus, sp. nov. 



Black ; the base of the abdomen with two sutures at the base, the 

 space between them laterally depressed, smooth, shining, and marked 

 with stout keels ; the under side of the scape, the clypeus, a mark, 

 longer than broad, and with the lower half much narrowed above the 

 antennae, the inner half of the eye incision, a large triangular mark 

 on the sides of the pronotum, the tegulas, post-scutellum, and a line on 

 the first and second abdominal segments, yellow. Legs black, the 

 knees, the four front tibife anteriorly, and the tarsi, testaceous. Wings 

 hyaline, the radial cellule smoky, the base hyaline. <? . Length, 

 7 mm.
