128 [June, 



The re-establishment of a sawmill last winter in another and more likely clearing 

 in our pine woods, near burnt ground, afforded the right sort of place for these 

 two insects, and both of them were found quite at home, on May 12th, beneath 

 planks and logs left resting on the sawdust and chips accumulated round the 

 mill. Asemuni striatum was about on the cut timber, and Eniamis histrio 

 and Coninomus carinatus and nodifer (all three in numbers), Aloniaria hadia, 

 Gliachrochilus (Ips) A-gnttatus and A-punctatus, Pityophagus ferrugineus, and 

 Trichophya pilicomis, etc., were to be found on the moist under-surfaces of 

 the freshly-cut boards.* — G. C. Champion, Ilorsell : May \bth, 1917. 



A note on Cryptocephalns bipunctatus L., etc. — In reference to Mr. W. E. 

 Sharp's valuable paper on this beetle {antea pp. 76-79), it seems to be only 

 fair to Mr. R. S. Mitford to mention that he was the first to take the type form 

 in Britain, in 1907. He kindly told me whereabouts he had taken his two 

 specimens, at Niton, I. of W. ; and in July, 1908, I went down there, and, 

 after a strenuous hunt, succeeded in linding its headquarters and secured a 

 number of examples. Next year I gave Mr. Pool a plan of the spot, and he 

 went down to help Mr. Mitford to obtain more. It may also be mentioned 

 that the var. thomsoni was taken by Mr. Ilereward Dollman at Lewes. 



With regard to Mr. Sharp's remarks on the bionomics of the species — the 

 larva and larval case will be found to be described (and the latter figured) by 

 Rosenhauer [" Ueber die Entwicklung und Fortpflanzung der Clythien und 

 Cryptocephalen," Erlangen, 1852, pp. 1-34, Pf. 21]. This paper was referred to 

 by me in my life-history of Clythra 4-punctata L. (Trans. Ent. Soc. Lond. 1902, 

 li-25). 



In a few notes on Cryptocephali [Ent. Rec. xx, 208-9 (1908)] I mention 

 that all the species (as do Clythra, Labidostomis, and Gytumdrop/dhahna) lay 

 covered eggs, which they let fall ; that the larva, when hatched, builds a 

 case on to this egg-case, and that some of them feed on lichen on trees. 

 Dr. Chapman sent me a larva in a case taken on lichen on a tree in the 

 New Forest, and when this hatched it proved to be C. pnrvtilus Miill. 



Wasmann suggests that from some short notes by Weise it is probable that 

 all the species of Cryptocejjhaliis change to pupae in ants' nests. Tiie late 

 Mr. A. J. Chitty once captured a specimen of C. 6-punctatiis near a nest of 

 i*^. rufa, and expressed his opinion that it bad come out of this nest. 



In April 1910, I found a Crypt ocepJiahis larva, in a case, in a nest of Acan- 

 thomyops {Deiidrolasius) fidiginosus at Wellington College [Ent. Rec. xxiii, 

 170 (1911)]. This was taken home and placed in an observation-nest with 

 some of the ants, carton, and contents of the nest. The larva fed on the refuse 

 of the nest and enlarged its case in the same way as does a Clythra larva. It 

 fastened the case to a bit of wood at the end of May, and hatched out in the 

 middle of June, proving to be a specimen of C. fulvus Goeze. The adult beetles 

 feed on the leaves of various trees and plants, grass, etc. 



Rosenhauer {I. c.) gives the life-history of C. 1'2-pimciatus, from the e^g to 

 the imago. — Horace Donisthorpe, Ilazlewell Road, Putney : April, 1917. 



* Since this note has been in type, I have taken an examp'e of Silvanus bidentatus F., from 

 Tinder pine bark, at the same locality. — U. C. C.
