Sp. 2. castanea. Oblongo-ovata, elytris castaneis, capite thoraceque fiavis. 



(Long. corp. 2 lin.) 

 Si. castanea. Marsham. — Tr. castanea. Steph. Catal. 89. No. 951. 



Oblong-ovate, shining, glabrous: head and thorax ochraceous-yellow : eyes 

 brown : elytra pale castaneous, very obsoletely striated ; antenna castaneous 

 brown : body beneath yellowish : legs pale reddish-yellow. 



' I suspect that this insect— of which I possess the original specimen, described by 

 Marsham — is a small immature variety of the preceding; it is decidedly not 

 the Antherophagus pallens as referred to by Gyllenhal, and recently given as 

 a second species of that genus as above referred to. 



Found near London, and in Gloucestershire. 



Sp. 3. aenea. Oblongo-ovata, rufo-ferruginea nitida, ante.nnis nigris, elytris 



ceeruleo-virescentibus, thorace postice marginato. (Long. corp. 2 lin.) 

 Tr. aenea. Fabricius. — Steph. Catal. 89. No. 952. 



Oblong-ovate: shining rusty-red: head punctate; eyes and antennae black: 

 thorax punctured, its lateral and posterior edges margined: elytra bluish- 

 green, very glossy, punctate-striate, the interstices finely punctulated: scu- 

 tellum rufous : body punctulated beneath: legs reddish. 



Distinguished from the two preceding by having the breast rufo-ferruginous, 

 and from the two following by the antennae being entirely black: the scutellum 

 rufous, and the thorax margined behind. 



Not common : I once found a pair in Coombe-wood. 



Sp. 4. bicolor. — Plate xvii. f. 4. — Oblongo-ovata, rufo-ferruginea, nitida, elytris 



nigris, antennis fusco-piceis, basi ferrugineis. (Long. corp. 2 lin.) 

 Si. bicolor.— Marsham. Tr. bicolor. Steph. Catal. 89. No. 953. 



Oblong-ovate, rusty-red, shining ; head as in the last ; eyes black : antennae 

 ferruginous at the base, the rest pitchy-brown, with the terminal joint some- 

 what testaceous: thorax punctate, the disc convex; the lateral edge alone 

 margined : scutellum rufous : elytra glossy black, rather deeply punctate- 

 striate, the interstices irregularly punctate: body punctate : legs rusty-red. 



The black elytra, with the ferruginous base of the antennae, the absence of a 

 margin to the posterior edge of the thorax, and the greater bulk of this species, 

 distinguish it from the former ; from rufipes it may be known by the rufous 

 scutellum, more slender form, the deeper striae on the elytra, and the rufous 

 under surface of the body. 



Rare : I possess a pair from the Marshamian collection, and I once 

 beat a single example from a birch-tree in Coombe-wood in June.
