rugulose, the medial area more or less distinct ; 1st abdominal 

 segment with a medial carina bifurcate at the base, longitudinally 

 striolate, like the 2d ; segment 3 more or less testaceous, more finely 

 striolate, posteriorly smooth, the striolae have a tendency to di- 

 varicate from the medial line and become transverse ; the re- 

 maining segments smooth, extreme apex of the abdomen rufescent; 

 the hind femora at least are always tipped with black, by which 

 the species may be known. The c? has also 34-jointed antennae in 

 my specimens, longer than the body ; the rugulosity of the 3d 

 segment is more pronounced, and straight ; in one example the 

 hind coxfe are infuscated. 



Neither umhratiUs nor vestigator, Hal., can be this 

 species, as their hind femora are concolorous, a reason 

 which Haliday himself gives (Ent. Mag., iv., 96) for not 

 uniting uinbratilis and exsertor. 



Not uncommon near St. Albans ;' I have five males 

 and one female from that neighbourhood, and a ? taken 

 in Darenth Wood. Elisha bred a dark $ from Hedya 

 negUctana, Dup., on July 31st.

Black ; mouth, orbits, markings of the thorax in front, abdomen 

 at the apex, and legs, testaceous ; abdomen striolate at the base, 

 segment 1 obconic ; terebra f the length of the abdomen. ? . 

 Length, 1\ — 2 ; wings, 3 — 4i lines. 



Like excuhitor, Hal., differing principally in the sculpture of the 

 abdomen ; segments 1 — 2 somewhat shining, finely striolated, the 

 interstices impunctate ; the other segments dull testaceous, or 

 mfuscated, 3d mmutely aciculated transversely, the following 

 almost smooth ; belly pale testaceous ; head testaceous, face 

 beneath the antennae, middle of the vertex, and rim of the occiput, 

 fuscous ; thorax in front, at the sides, and beneath, testaceous, on 

 the disk are three confluent fuscous patches ; metathorax black, 

 punctato-reticulate, without areas ; legs pale testaceous ; wings 

 hyaline, stigma pale testaceous, fuscous at the apex. The <? differs 

 in having the posterior abdominal segments less abbreviated and 

 more broadly smooth; the exterior nervures of the wings are 

 sometimes incrassated; antennae (in one specimen) 28-jointed. 



Antennae $ BO-jointed, as long as the body, blackish above, 

 ferruginous beneath, joints 1 — 2 testaceous ; prothorax testaceous
