172 MANDIBULATA. — COLEOPTERA. 



deeply striated. Three specimens in the British Museum, which are appa- 

 rently distinct species from var. «. 



One of my specimens of this species was cauglit near Norwich ; 

 the others were taken near Hull, by W. Spence, Esq. " Grampian- 

 hills."— E^f. F. W. Hope. " Zetland."— i^et;. J. Fleming. " Swan- 

 sea." — Dr. Leach. 



Sp. 2. rubens. Testaceo-ferrugineus, capite Jkiscescente, thorace rufo-ferrugineo, 

 elytris versus apicem obsolete cceruleo micantibus, tenue striatis. (Long. corp. 

 2ilin.) 



Ca. rubens. Fabricius. — Bl. rubens. Steph. Catal. p. 35. No. 333. 



Rusty-testaceous : head rather dusky, with an arcuated impression on each side : 

 thorax rusty-red, rather convex, with a deep central channel, and a deep de- 

 pressed fovea on each side near the posterior angles : elytra pale testaceous, 

 with a bluish gloss towards the apex of the disc ; rather faintly striated, the 

 striae simple : legs and antennae pale ferruginous. 



Taken occasionally in gardens in the vicinity of London, at 

 Lambeth, first by Dr. Leach, afterwards by myself. " Chelsea."" 

 — Mr. Westwood. " Hackney marshes." — Mr. Chant. " Windsor." 

 Dr. Leach. " In a water meadow at Thruxton, Hants." — Liev. G.

Sp. 3. unifasciatus. Rufo-ferrugineus, oculis elytrorumque fascid posticd nigris, 



elytris obsoletissime striatis; pedibus ochraceis. (Long. corp. 2 — 2^ lin.) 

 Ca. unifasciatus. Panzer. — Bl. unifasciatus. Steph. Catal. p. 35. No. 334. 



Allied to the last ; rusty-red : head smooth, with a deep impression on each side 

 round the eyes, the latter prominent, black : thorax obcordate, rather convex, 

 with a deep longitudinal line, and a simple depression at the hinder angles 

 on each side : elytra slightly pubescent, obsoletely striated, ferruginous, with 

 a bluish-black fascia towards the tip : body beneath pale reddish : legs oehra- 

 ceous or pale testaceous. 



Var. /3. With the head black, the elytra testaceous, with a common dorsal black 

 spot. 



This variety is probably the Ca. discus of Fabricius, but of that insect he says, 

 " thorax rotundatus," which character neither suits this insect nor any other 

 of this genus. 



This species has been found in the neighbourhood of London ; 

 it also occurs in Norfolk and Suffolk, though very sparingly, and is 

 usually caught upon the wing. " Greenwich road, in June." — 

 Mr. Ingpen. 



f Sp. 4. longicornis. Elongatus, capite nigro, thorace elytrisque brunneis, an- 

 tennis, palpis pedibusque brunneo-Jlavis, elytris striatis, pimctis tribus impressis. 

 (Long. corp. 2 } lin.)
