ELATERID^. 143 



A. subfuscus, Miill. This is evidently a Scotch insect ex- 

 ckisively, and the record from Llangollen (Brit. Col. iv. 102) 

 must be omitted. The insect recorded from that locality as A. subfuscus 

 is probably a small form of ^1. luemorrhoidalis, F., which is common 

 there : my series of the latter insect varies from S mm. to 15 mm. in 

 length. 



ADRASTUS, Eschscholtz. 



A. limbatus, F. (Geo. Ins. 1777, 235). There is considerable 

 confusion with regard to the synonymy of this insect : this was first 

 noticed by Mr. Gorham and afterwards by Mr. Nevvbery ; the insect 

 standing under the name in our collections should, apparently, be 

 referred to ^I. nitichdus, Marsh. •= pa^/eHs, Er., and may be known 

 from A. limbatus (which has not yet been recorded as British) by the 

 following characters : 



I. Antennfe longer, black or brownish with 



the base testaceous, third joint about 



double as long as second . . .A. limbatus, F. 



ir. Antennte shorter; entirely testaceous; 



second and third joint subequal . . A. nitidulus. Marsh. 



In the European Catalogvie (1906, Col. 391), the confusion is made 

 worse confounded by the synonymy, which is as follows : 



A. limbatus, F, Gen. Ins. 1777, 235. 



nitidulus, Marsh., Ent. Brit. I. 1802, 380. 

 A. nitidulus, Marsh., Ent. Brit. I. 1802, 380 {sic), 



limbatus, Payk., Fn. Su. III. 1800, 43. 



A, nitidulus, it will be noted, is here given (with the same reference) 

 as a synonym and as a good species. 



CORYMBITES, Latreille. 



C. impressus, F., var. ruiipes, Schilsky (Deutsch. Ent. Zeits. 

 1888, 187). This variety has the legs red: it is, apparently, the 

 "var. pedihis ferrugineis" of Erichson (Naturg. Ins. Deutsch. iv. 

 292) ; according to him the legs vary from black through shades of 

 pitchy-brown to ferruginous. It is recorded from Barron Wood, 

 Cumberland, by Mr. Donisthorpe (Ent. Record, 1903, p. 263). 



C. bipustulatus, L., var. semiflavus, Fleisch. (Wien. Ent. 

 Zeit. 1886, 235) = flavescens, Schilsky (Deutsch. Ent. Zeits., 1888, 

 1 90). This is the variety with the elytra entirely testaceous. I have 

 before referred to it (but without name) (Brit. Ool.iv. 115): it resembles 

 the var. ocliropterus, Steph., of C. quercus, Gyll., but may be known by its 

 shorter, less parallel -sided and less closely punctured thorax, and the 

 more rounded sides of the elytra, as well as by the shorter antennfe 

 and the non-carinate posterior angles of the thorax.
