ADEPHAGA. S' 



reintroduced this species as British and says that he has examples from 

 Bradfield and Southport. Subsequently (Ent. Mo. Mag. xlv. (2 Ser. xx.) 

 1909, 12) he withdrew the specie*, saying that the insects leferred 

 to as belonging to JS\ jmsillns are merely X palustris with very dark 

 legs. Mr. Champion {l.c. 1908, 271), referring to a small mountain 

 form of X. aquaticus recorded by him in 187o * (Ent. Mo. Mag. x. 

 158), comes to the conclusion that the form is probably the N. strigifrons 

 of Baudi, which is really a variety of K. aquaticus. Subsequently however 

 {I.e. 1909, 12) he comes to the conclusion that it is rather a variety of 

 iV. jyusillus. It would, however, considering the great variability of 

 the insects, be best perhaps to regard both X. jyusillus and iV. strigifrons 

 as varieties of X. aquaticus. Extreme forms are very different in the 

 genus, but they are in many cases closely connected by intervening 

 examples. Dr. Joy records X. strigifrons from Dalwhinnie and Blair 

 Athol, and Mr. Donisthorpe from CarrantuohilJ, Co. Kerry. 



IV. hypocrita, Putz, Mem. Liege 66, 157; Spaeth, Verb, zool.- 

 bot. Ges., Wien. 49, 1899, 517. Dr. Joy (Ent. Mo. Mag. xliv. (2 Ser. 

 xix.), 1908, 103) also introduces the above species as British, and says 

 he has examples from Bradfield, Wellington College, Lundy Island and 

 Garve, Ross, and that it is probably generally distributed. It is distin- 

 guished by having the tibite reddish, and is narrower and more convex 

 than X. jxdustris, and the external interstices of the elytra are distinctly 

 alutaceous. It is said to bear somewhat the same relation to X. 

 palustris as X. substriatus, Wat. does to X. biguttatus, F. I have always 

 thought that X. suhstriatns was only a variety, and it is most probable 

 that X. hy2)oci'ita cannot be regarded as more than a race of 

 X. palustris. 



In Brit. Col, i. 11, 12, I have wrongly written X. quadriguttatus, 

 Dej. for X. quadrip)unctatus, Dej. ; this species is very like^V, biguttatus, 

 but apart from the two large pores on the elytra, it may be distinguished 

 by the almost straight sides of the thorax and its strong sculpture ; it is 

 probably rightly assigned specific rank, although some authors have 

 regarded it as a somewhat abnormal form of X. biguttatus. 



NEBRIA, Latreille. 



N. gyllenhalii, Schon, var. rufescens, Stroem. 1765 (= X. 

 arctica, Dej., Spec. ii. 235). This variety has the elytra and often the 

 tibise ferruginous or brownish yellow. It has occurred in the shingle 

 of the river Gelt in Cumbei'land and also in Scotland (Donisthorpe 

 Ent. Record xvii., 1905, 103), Ben-na-Buird (Donisthorpe, 1910). 



Var. balbii, Bon., Observ. Ent. i, 45, This is the variety with the 

 legs and usually the first joint of the antennae red, Ganglbauer records it 



* Mr. Champion says that "the insect in question is much smaller than the 

 typical i\". aqvaticus, bronze or bluish-bronze in colour, and has the second and 

 third joints of the antennas wholly or in part testaceous, the prothorax much 

 narrower behind, and the elytra very finely punctate-striate, the striae almost 

 obsolete towards the apex,"
