and emarginate ; mandibles not stout, centrally canaliculate nearly to the 

 base, with the teeth subequal. Antennae half length of the body, filiform, 

 immaculate and subpilose with twenty-two flagellar joints, of which the 

 apical is obtusely conical and somewhat large. Thorax black and nitidu- 

 lous with the mesosterna, excepting the interpectoral sulcus, and obsolete 

 callosities before the radices testaceous ; notauli not reaching centre of 

 mesonotum ; metathorax convex, nitidulous and subglabrous throughout 

 with only the lateral carinae, rising at the circular spiracles, indicated ; 

 petiolar area wanting and foveate on either side. Scutellum black and 

 subdeplanate. Abdomen immaculate, strongly and coarsely punctate with 

 the apices of the segments smoother and transaciculate ; basal segment 

 hardly half again longer than broad and bicarinate only to its centre ; 

 segments two to four subcompressed and a little longer than broad, the 

 remainder transverse ; venter dull flavidous ; terebra exactly as long as 

 the body, its valvulae black, elongately pectinate with their apices sub- 

 acuminate and the spicula pure white with the apex alone castaneous. 

 Legs entirely pale fulvous with the apices of the tarsi alone nigrescent ; 

 basal joint of the front tarsi emarginate with its calcar hardly curved ; 

 apical joint of hind tarsi twice longer than the penultimate, claws small 

 and strongly lobate basal ly. Wings not at all clouded ; stigma luteous ; 

 radix and tegulae pale fulvous ; areolet triangular, much broader than 

 long and distinctly sessile ; lower wings with apical abscissa of radius 

 about as long as the second recurrent ner^aire ; nervellus subopposite and 

 intercepted distinctly a little below the centre. 9 • Length, 7 mm. 



It is closely allied by its buccate head with E. strohilonim and E. glabra/ us, 

 Ratz., but differs in its red legs and distinctly sculptured abdomen. The 

 curious white spicula leads one to conjecture if this could have been the 

 female assigned to E. misocentnis by Desvignes (Cat. 87). 



The above description is drawn from a single female, which was bred 

 in May, 1901, at Bristol from Sesia tipiiJiformis by Mr. H. J. Charbonnier, 

 and is now in my collection.

A somewhat small brown species with the thorax partly red. Head 

 posteriorly narrower than the eyes, the mandibles ferrugineous with their 

 base and the palpi white; face immaculate, finely and evenly punctate 

 throughout, clothed with fine, sparse, silvery pilosity ; clypeus transverse, 

 shining, deeply discreted and apically depressed in the centre ; mandibles 

 broad and subglabrous, with the upper tooth slightly the longer ; vertex 

 finely punctate and shining, posteriorly emarginate in the centre, not 

 narrow, with the occiput bordered. Antennae longer than half the body, 

 basally dull red with the apical half often much paler ; basal flagellar 

 joints elongate and apically subnodulose; J with the scape internally and 

 beneath stramineous. Thorax subcylindrical ; prothorax black, discally 

 white ; mesothorax red, with a i)ropleural callosity before the radix stram- 

 ineous; mesonotum evenly and distinctly punctate, with notauli reaching 

 the centre; mesostcrnum in front, a central discal vitta, the scutellar and 

 in J specular regions, black; metathorax black, evenly punctate and 

 pilose to near the glabrous apex, with no trace of areae nor costae, in (J 

 centrally subcanaliculate ; spiracles circular. Scutellum and postscutellum 

 red, the latter and apex of tlie former often stramineous. Abdomen
