(i). 2. Areola normal, sub-quadrate ; meso- and meta- 



notum fla\'ous-marked 2. M aculatus, Mori. 



I. glabratus, sp. n. 



Head buccate, black; cheeks sparsely punctate; clypeus apically broadly 

 rounded, of $ transversely produced and piceous centrally ; palpi, labruni, 

 mandibles, and usually the external and vertical orbits, pale ; ? with apex 

 of clypeus also red ; $ with face and clypeus also flavous. Antennae 

 black ; scapes contiguous in both sexes, of $ pale beneath ; ? with fourth 

 flagellar jouit quadrate. Thorax obsoletely punctate, shinhig, black ; meso- 

 notum of ? somewhat deplanate, of $ normal ; mesopleurae and sterna 

 sub-glabrous and strongly nitidulous ; metathorax of normal length, its 

 costae weak ; areola very small, sub-circular, apically emarginate. Scu- 

 tellum glabrous, shining, flavous, apically sub-truncate ; of $ very flat, 

 of $ normally convex and carinate nearly to its centre ; post-scutellum 

 flavous. Abdomen strongly nitidulous, sub-glabrous, black ; of ? with 

 the two basal segments, except the petiole, flavous ; terebra black, shortly 

 exserted and rising far from apex ; of c? with the three basal segments 

 entirely flavous, and the second and third ventral plicate, the ultimate 

 being obtusely a little produced with the valvulae black. Legs normal, 

 glabrous, flavous wnth the coxae and hind trochanters black ; anterior 

 trochanters of ? piceous ; anterior femora internally canaliculate. Wings 

 flavescent, normal ; areolet pentagonal ; nervures, stigma, tegulae and 

 radix fulvous, darker in $ . Length, 12-13 mm. 



The $ has the external or vertical orbits, or both, pale ; its areolet is 

 sometimes broad and at others nearly coalesced above. 



I am indebted to the Rev. H. S. Gorham, f.z.s., &c., for a female and 

 three males of this very distinct species ; but beyond certifying to their 

 British origin, he could tell me nothing regarding their history. 



2. maculatus, sp. n. 



Head sub-buccate, of $ transverse ; black ; cheeks glabrous ; clypeus 

 apically broadly rounded and centrally marginate ; mandibles strongly 

 obtuse with the teeth sub-obsolete ; face, clypeus, mandibles except their 

 apices, palpi, lower half of exterior orbits nearly to base of mandibles, the 

 frontal, and in ? vertical, orbits broadly flavous. Antennae black ; scapes 

 pale beneath, of $ inserted nearer the eyes than each other, of ? con- 

 tiguous with the seventh flagellar joint quadrate. Thorax obsoletely punc- 

 tate, shining, black ; mesonotum somewhat flat, with a central flavous 

 patch ; pronotum, a long pre-radical line, two large patches on the meso- 

 pleurae, another on the metapleurae, and the areola, flavous ; mesosterna 

 indistinctly rufescent ; $ also with small pale callosities beneath both pairs 

 of wings ; mesopleurae and sterna obsoletely punctate and nitidulous ; 

 metathorax elongate, convex ; costae distinct, though fine ; areola some- 

 what large, sub-quadrate, apically truncate. Scutcllum glabrous, shining, 

 flavous, apically sub-truncate, carinate beyond its base ; of ? very flat, of 

 (J strongly convex. Abdomen strongly nitidulous, glabrous ; of ? entirely
