developiiieut " would sugL>-est that they also may be referable to 

 B. dttpJicatus. Captain Saiiite- Claire Deville says that iu France this 

 species is the rarer of the two, and appears to be confined to the 

 Armorican peninsula and to Limousin. Undoubtedly this species is 

 the ^ellucidus, Boh., of Seidlitz. 



B. pellucid2(s, Mr. ISTewbery informs me, is widely distributed in 

 Britain. It first occurred to me (a sinofle specimen only) in June, 

 1900. On discovering in 1909 that it was distinct from my other 

 exponents of the species, I searched for it in June and July, and 

 captured about 60 examples. The males were in the proportion of one 

 to four females. I took it by sweeping in damp ground in woods at 

 Ivybridge, but failed to detect its food-plant, nor has the insect 

 occurred to me in any other place in the district. Mr. Newbery has 

 taken two females of it at Higham's Park. The females seem to vary 

 in size very much. 



B. pyrenseus. Since my original discovery of this species (Ent. 

 Mo. Mag., xxxiii, 134) it has occurred in numbers all over the Ply- 

 mouth district. The noteworthy fact about it is, however, that it 

 seems — (temporarily, at least) as far as my single-handed efforts may 

 be considered of value on such a subject — to have replaced aranei- 

 formis, as I have not met with this latter insect at all since about 1898, 

 and when recently I wanted a few I applied to my friend, Mr. de la 

 Grarde, to supply them from his abundance of that species at Christow. 

 Following up the distribution of pyrenxus, by the courtesy of Mr. F. 

 E. Rowley, I had the loan of the examples of araneiformis in the col- 

 lection (now located in the Exeter Museum) of the late Mr. J. J. 

 Reading, of Plymouth. There were some half dozen specimens, and 

 all were true to name : no pyrenxiis was amongst them. Unf ortimately, 

 they were not labelled, but as Mr. Reading left Plymouth somewhere 

 about 1860 it is reasonable to assume that the insects were captured 

 previoiisly to that date, and I think that so keen an entomologist as 

 the discoverer of Actocharis would hardly have overlooked pyreneetis 

 had he ever seen it. Now, one more point. Prior to 1S94 the Rev. 

 T. A. Marshall resided at Botusfleming, Cornwall, and collected various 

 Orders of insects. His collection of beetles (or rather the residue 

 thereof, after many vicissitudes) is now in my possession, and it is 

 remarkable that in his small series of four beetles standing as aranei- 

 formis two are pyrement^. They are carded, with " Bfm." written 

 underneath, but no date. In 1897, Mr. G. C. Champion, F.Z.S., re- 

 corded pyrenseus from Portscatho, Cornwall (Ent. Mo. Mag., xxxiii,
