Var, 1. Head, thorax, and antennae, black ? ; antennae S' testa- 

 ceous at the base. 



Var. 2. Head and thorax ferrugmous varied with black; antennae 

 fuscous. 



Var. 3. Head and thorax ferruginous ; antennae testaceous, 

 darker at the base and apex. 



Var. 4. Stigma fuscous. 



Antennae J 17 — 22-jointed ; thorax smooth, shining ; meso- 

 thoracic sutures meeting in a rugulose depression ; at the base of 

 the scutellum is a bipartite rugulose foveola ; metathorax reticulato- 

 rugulose, with or without two carince indicating the medial area 

 between the two dorsal ; abdomen regularly ovate, ' depressed, 

 pellucid (the ova, according to Nees, being visible in life, strung 

 into a series posteriorly towards the oviduct) ; segment 1 trans- 

 verse, the membranaceous edges depressed, scutum oblong, 

 rectangular, more or less rugulose, or even smooth ; terebra one- 

 fourth or one-sixth the length of the abdomen. The <? is much 

 smaller, with 24 — 25-jointed antennte. 



Abundant at the roots of rushes on the sand-hills at 

 Freshwater Bay, Pembrokeshh-e ; most of these belong 

 to the dark varieties {piciventris, Wesm.). Found in 

 moss at the roots of trees, or shaken out of furze and 

 dead leaves in spring ; St. Albans, Maldon, Worcester, 

 Headley Lane, &c. Bred by Brischke from Tortrix 

 corylana, Fab. Cocoons thin, white, cylindrical, attached

IX. EHOGADIDES. 



Head transverse, occiput margined ; mandibles bifid ; maxillary 

 palpi 6-, labial 4-jointed; abdomen sessile, segments 1 — 3 largest, 

 Bculptm-ed, thyridia of the 2d and 8d visible ; three cubital areolets, 

 the 2d rectangular (in CUnocentrus and Pelecystoma, trapezoidal) ; 

 recm-rent nervure rejected ; pobrachial areolet longer than the 

 priEbrachial ; anal nervure not interstitial ; terebra subexserted (in 

 CUnocentrus and Pelecystoma, exserted). 



The insects of this very natural division are of large 

 or moderate size, and robust structure, with elongate 

 antenna; and abdomen ; their integuments are hard, 

 and more or less covered with rugulosities or punctures ; 

 their colours are black, testaceous, and rufous, the last 

 appearing chiefly in bands upon the abdomen, or alter- 

 nating with black upon the head and thorax of the 

 typical Ehogades. They are parasites of lepidopterous 

 larvse.
