62 Rev. T. A. Marshall's monograph of 



it, silaceous, as distinguished from fiavo- or rrrfo-testaceous. Before 

 the scutellum is a tranVersely oval fovea, bisected hy a carina. 

 Distinguished from fulvipes, Hal., hy longer and more slender 

 antennae ; from parvulus, Euthe, hy longer antennae ; from both 

 hy having traces of the mesothoracic sutures. 



Reinhard conjectures this to be Microdontia clavi- 

 ventris, Wesra., ? (Nouv. Mem. Ac. Brtix., 1835, p. 71), 

 but Wesmael's description is inconclusive through the 

 omission of all mention of the mesothoracic sutures ; 

 moreover, the types in the Brussels Museum do not 

 correspond with the description, and the whole is 

 rendered useless. 



Described from two females taken in Epping Forest.

Eufo- or flavo-testaceous, antennae at the tips, apex of the abdo- 

 men (sometimes also the metathorax, pleurae, and pectus of the J ) 

 fuscous ; hind femora and tibiae in the middle rarely infuscated. 

 Wings fuscescent, with a broad whitish transverse fascia including 

 the base of the stigma, the rest of which is brown ; when the wings 

 are paler this fascia is absent : cubital and anal nervures very 

 faint, and their transverse nervures indistinct. Metathorax elon- 

 gate, horizontal, subtruncate. Abdomen clavate, 1st segment 

 slender, linear, curved ; tubercles not prominent. $ 2 • Length, 

 1 — If ; wings, If — 2J lin. 



Variable in size, and in colour from flavo-testaceous to rufous ; 

 abdomen from the hinder edge of segment 2 to the apex always 

 blackish. The base of the petiole, the metathorax, pleurae, and 

 pectus of the J frequently fuscous ; near the radix of the wings is 

 a fuscous dot. Fore wings infuscated from about the prsebrachial 

 transverse nervure, and gradually paler thence to the apex, crossed 

 by a broad whitish fascia under the stigma ; this coloration is less 

 obvious in smaller specimens, especially males, and at length dis- 

 appears, as in that figured by Curtis. Costa and prsebrachial 

 transverse nervure brown ; the other nervures not distinct. Po- 

 brachial areolet of the hind wings open. Eyes during life green ; 

 ocelli fuscous. Antennae $ 17 — 19-jointed; of the ? 16-jointed ; 

 the two apical joints imperfectly divided; 3d joint elongate.
