base, the apical angles smooth, depressed. Terebra as long as the 

 body without the head. <? $ . Length, If ; wings, 3^ lin. 



This species serves as a connecting-link between 

 Diospilus and Aspidogonus ; it forms the genus Ano- 

 stenus, Forst., characterised by the shape of the 2d 

 cubital areolet. 



Common in many places, especially in a wood near 

 my house at Nunton, Wilts ; taken once by Haliday in 

 Ireland ; also noticed in Belgium and Germany.

Palpi maxillares 6-, labiales 4-articiilati. Clypeus brevis, trans-

 distinctis. Metathorax regulariter areatus. Areola cubitalis 2da 

 magna, trapeziformis ; nervus recurrens interstitialis ; areola prae- 

 discoidalis petiolata ; radii abscissa Ima elongata, 2d8e fere sequaUs ; 

 areola radiahs lata, cultriformis, aim apicem attingens. Pedes 

 crassi, longiusculi. Abdomen oblongum, ovatum, sessile, lateribus

Maxillary palpi 6-, labial 4-jointed. Clypeus short, transverse, 

 bisinuated on the front edge, and elevated ; with 2 basal foveae. 

 Metathorax regularly areated. Second cubital areolet large, 

 trapeziform ; reciu-rent nervure interstitial ; praediscoidal areolet 

 petiolated ; 1st abscissa of the radius almost as long as the 2d ; 

 radial areolet broad, cultrate, reaching the apex of the wing. Legs 

 Btout, of moderate length. Abdomen oblong-ovate, sessile, rounded 

 at the sides. Terebra elongate. 



Head somewhat transverse, not wider than the thorax, produced 

 behind the eyes ; occiput concave, margined. Mandibles retracted, 

 a space being left between them and the clypeus, which is raised 

 on the front edge, as in the case of certain Opiides. Front 

 slightly excavated. Prothorax produced. Mesothoracic sutures 

 distinct. Mesopleurse smooth, shining, with a crenate fovea. 

 Outer side of the 2d cubital areolet decolorous ; pobrachial areolet 

 longer than the praebrachial ; anal nervure not interstitial. Eadial 

 areolet of the hind wings contiguous ; pobrachial areolet bisected 

 by a transverse nervure ; pobrachial nervure obsolete. Abdomen 

 elongate-ovate, not longer than the thorax ; 1st segment broad, a 

 little longer than its apical width, bicarinated, striolated; the other 

 segments smooth and shining ; segments 2 — 3 forming together 

 half the length of the abdomen ; suturiform articulation obsolete ; 

 apical segments very short. Terebra as long as the body, or longer. 

 Sexes similar.
