HETEROCERIDJE. HETEROCERUS. 101 



" Near Aberystwith." — Rev, F. W. Hope. " In a mud-bank near 

 Tottenham."— Mr. Stone. 



Sp. 2. flexuosus. Fuscus, pubescens, elytris luteis, vittd longitudinali Jlexuosd 

 nigra, pedibus juscis, tarsis piceis. (Long. corp. 2 lin.) 



He. flexuosus mihi. — Steph. Catal. p. 55. JVo. 553. 



Fuscous, pubescent, finely punctured: head and thorax immaculate: elytra 

 luteous, with a longitudinal flexuous stripe, composed of irregular black spots, 

 an elongate black patch at the humeral angle, and a rather obsolete one a little 

 behind the middle towards the suture, the apex immaculate : body beneath, 

 and legs, fuscous, the latter with the tarsi pitchy. 



Taken on the banks of the Thames, beyond Gravesend. 



Sp. 3. Marshami. Niger, puncto ad basin thoracis apicemque elytrorwm lutco 

 obscuro, pedibus luteis. — Marsham MSS. (Long. corp. l^lin.) 



He. Marshami mihi. — He. obsoletus. Marsham MSS. — Steph. Catal. p. 55. 

 JVo. 550. 



Similar to the following, but less than var. /3: the entire body dusky-black, 

 tomentose : thorax with a small obscure luteous spot in the middle of the base ; 

 the elytra also, towards the apex, have a similar spot : body beneath dusky 

 black : legs luteous. — Marsh. MSS. 



The name obsoletus, which was obtained from my rough Catalogue, having 

 been erroneously, though perhaps not inaptly, applied to another species of 

 this genus, it has become necessary to change the one printed in the Catalogue 

 itself, from the MSS. of Mr. Marsham, whose specific character and descrip- 

 tion, above given, evidently do not apply to the insect which has lately been 

 published as the He. obsoletus of Leach MSS.; a name which neither occurs 

 in the Doctor's MSS. nor in the collection at the British Museum. 



I am not aware of the locality of this species, but as Mr. Mar- 

 sham obtained it from Mr. Spence, I presume it inhabits the banks 

 of the H umber. 



Sp. 4. hevigatus. Fuscus, pubescens, elytris maculis in fascias irregulares dis- 



positis, pedibusque testaceis. (Long. corp. 1^ — 2\ lin.) 

 He. laevigatas. Fabricius. — Steph. Catal. p. 55. JVo. 551. 



Fuscous, glossy, finely punctured, and slightly pubescent: head and thorax 

 generally immaculate, the latter rarely with a pale spot at the anterior angle : 

 elytra with the margin and several large, subquadrate, pallid spote, disposed 

 in three irregular fasciae: these spots are very variable in form and size; 

 they are sometimes nearly confluent, at others distinct ; and are usually placed, 

 two longitudinally towards the scutellum, two others behind these, near the 

 suture, and a third pair towards the apex of each elytron ; the pale outer 

 margin of the latter is indented opposite the intermediate space: the body is 

 frequently testaceous beneath ; and the legs pale-testaceous, with the tibiie 

 sometimes dusky.
