Sphex, Fabr. 

 Sphex {Piiononyx) laenna, sp. n. 

 Long. 28 millim. 



Hab. Mexico, liio Papagaio in Guerrero, 1200 feet {H. H. 

 Smith). 



Agrees in coloration with S. Thomce, Fabr., except that the 

 uings are deep dark violaceous ; differing otherwise in being 

 much longer, in the thorax wanting the thick pale pubescence, 

 and in the scutellum being broadly furrowed down the 

 middle. 



Eyes parallel. The hinder ocelli separated from each other 

 by about the same distance they are from the eyes. Cheeks 

 and clypeus covered with silvery pubescence ; the vertex 

 sparsely clothed with moderately long black hair, below the 

 antennae with longer black hair. Apex of the clypeus 

 transverse and with a small indentation in tiie centre ; the 

 sides broadly rounded. Behind the ocelli is a shallow curved 

 furrow, behind which at the sides is a small roundish depres- 

 sion ; there is a shallow longitudinal furrow between the 

 ocelli and at the sides of the hinder pair, the front one being 

 surrounded by a furrow. Tiie scape of the antennae is sparsely 

 covered with long black hair; the flagellum jiruinose. The 

 pronotum is depressed near the base, the depression being 

 shining and impunctate; the ai)ex is finely transversely 

 shagreened and slightly longitudinally depressed in the 

 middle ; the pleurae alutaceous, except a shining spot on the 

 lower part at the apex; the base longitudinally striated; at 

 the aj)ex is a cnrvetl narrow fringe of pale golden pubescence. 

 Mesonotum opaque, covered with short pale hair ; closely 

 longitudinally striated, furrowed down the middle, the furrow 

 at the base wide. Scutellum wide, raised, the middle de- 

 pressed broadly; sluigreened, the sides shining,, impunctate. 

 Median segment alutaceous, covered closely with pale soft 

 l)air ; closely transversely striolated, the a|)cx before the 

 depression broadly iurrowed. The mesoj)leurte closely and 

 rather strongly, tiie metaplcurse obliquely, striated. The 

 petiole is black and is as long as the hinder coxas, covered 

 with long pale soft hair. The rest of the abdomen is shining 

 rufous ; a black triangular mark on the second segment, the 

 narrowed part at its base ; the third segment is broadly black 

 at the base. \\ ings unitbrmly dark violaceous ; the first 

 and secund transverse cubital nervures oblique, both bullaled 

 at the lower part, the third curved and much narrowed 

 towaids the second at the top, the space between them there
