86 Mr. Babington on Dromius. 



Sturmii ; but as they have omitted the width of their insects, it is 

 quite impossible even to guess which is the species intended. All 

 the synonyms given by Duftschmid belong to fasciatns. Fischer's 

 description is copied from Dejean. 



This insect has not as yet been discovered in Britain, all the re- 

 corded specimens being either 4-signatus or bipennifer, to the former 

 of which the locality given by Mr. Stephens belongs. 



9. D. bipennifer. Babington. Plate X. Fig. 3. 



Capite nigro ; thorace subquadrato, rufo ; elytris substriatis, an- 



tice pallidis, angulis humeralibus rotundatis, sutura, et pone 



medium fascia subdentata, fusca, macula terminali pallida ; 



corpore subtus, antennis pedibusque pallidis.

Elongated ; head shining, black ; thorax quadrate, narrowed be- 

 hind, rufous ; elytra obsoletely striated, with the humeral an- 

 gles rounded, the base pale, suture dark, and behind the middle 

 a dark transverse fascia slightly dentate in the middle of each 

 elytron anteriorly and dilated posteriorly on the outer margins, 

 but not to the apex, which is pale ; antennas and underside of 

 the body pale. 



This insect stands in the cabinet of Mr. Stephens under the name 

 of T>. bifasciatus, Dej., from which it differs in not having a triangu- 

 lar dark spot at the base of the elytra, the fascia not dilated anteri- 

 orly on the outer margins, and the underside of the body pale. 



It is very nearly related to D. sigma, under which name it appears 

 in the cabinets of Mr. Curtis and others, from which species it dif- 

 fers totally in size, (bearing the same proportion to D. sigma as 

 D. bifasciatus does to D. 4-signatus,) that species being much wider in 

 comparison with its length, and by having the humeral angles of the 

 elytra rounded instead of being nearly rectangular, as I believe them 

 to be in that species, which Dejean describes as agreeing exactly in 

 form and size with 4-signatus, and also somewhat in form with 4- 

 maculatus. It also appears to have been confounded with D. sigma 

 by the continental entomologists, and probably by Dejean himself, 

 as it has been received under that name from various parts of Eu- 

 rope by the Rev. F. W. Hope, to whom I take this opportunity of 

 returning thanks for his kindness in granting me the use of his spe- 

 cimens of this and other species of Dromius.
