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



the compound segment thus formed equalling by itself h of the 

 abdomen ; the remaining segments short, partially retracted beneath 

 the 2d, but not invisible as in the Pamholides ; radius originating 

 in the middle of the stigma ; 2d cubital areolet trapeziform, shorter 

 and less produced inwardly than in Hormius ; recurrent nervure 

 interstitial ; pobrachial areolet of the hind wings less than i the 

 length of the praebrachial. 



1. Chremylus ruhiginosus, Nees. (PI. III., fig. 2). 



Hormius ruhiginosus, Nees, Mon., i., 156, ? . 



Chremiilus riibiqinosus, Hal., Ent. Mag., iv., 51, ? ; 

 Cur., Farm Ins., 365, a^ ? ; S. v. Voll., Schets.,

Peneceriis ruhiqinosus, Wesm., Nouv. Mem. Ac. Brux., 

 1838, p. 70, ? , pi., f. 7 (wing). 



Castaneous; head, antennae at the apex, thorax and base of 

 abdomen more or less, and stigma, fuscous; palpi pale; terebra 

 \ — I of the abdomen. $ . Length, \ ; wings, f hne : ? , length 1 ; 

 wings, 2 lines. 



5 . Granulated, obscure ; scutellum and apical half of the 

 abdomen more shining ; metathorax rugulose, truncate, and bi- 

 denticulated at the hind angles, but less acutely than in Dimeris, 

 more or less distinctly di\dded into five areaa, the two dorsal large, 

 rounded behind, the medial projecting angularly between them ; 

 1st abdominal segment and base of the 2d punctulate, the former 

 semiorbicular, as in Dimeris, with two acute parallel carinse. 



The (? (which I have not seen) is similar, according 

 to Curtis, but only ^ as large, and is remarkable for 

 having one joint less in the antennae than the ? , the 

 ordinary sexual distinction being reversed : cf. Hal., 

 Ent. Mag., i., 266, where he appears to have established 

 the genus upon a ^ specimen, although in iv., 50, only 

 the ? is described. The same writer says that the 

 metathorax is " baud areatus " ; probably he had before 

 him a 2 in which this structure was not conspicuous, 

 as in my specimens, and in the six described by 

 Wesmael. 



Widely distributed, and often found in windows of old 

 houses : I have four females taken in such a situation in 

 Northamptonshire. According to Curtis {I. c.) it is a 

 frequent parasite of BrucJtus rujlmanus, Boh.; his speci- 

 mens were bred on April 24th from beans grown in 

 Essex; liondaui bred it from Brudius scDiinarius, L. ;
