iu C. 2cesfwoo(h\ the longer distal joints beiug furnished with 3 whorls of 

 upstanding specialized setae ; the outer setae basally are strongly feathered, 

 but on the inuer side they are modified, and are more or less clavate, with a 

 minute tooth near apex. The louirer niacrochaetae of pronotum, mesonotum 

 "feathered"' Avith a double row of ** pv)iuts." The marrochietae of anterior 

 martrin of pronotum only about 0*3 the length of those at each angle ; the 

 anterior niacrochaetae of mesonotum 4o-0'5 the leng-th of the one at each 

 hind angle ; the macrochaeta at each hind angle of the metanotum short and 

 stout, seemingly a well-developed pair of the moditiecl minor setae of the 

 posterior margin. Abdominal tergiies 1-7 each furnished with a pair of 

 anterior, and 8 and 9 wilh a pair of more widely separated posterior, sub- 

 median niacrochaetae ; 5-7 with lateral, and 5-9 with posterior, sublateral 

 macrochaetae present. Stylus much as in C. st/Jphi/linus, etc. Minor setae 

 slightly longer imd not so stout as iu lubbocki. 



Hah. 1 first detected this interestinor insect in a small batch col- 

 leeted b}-- Miss Evans at Fallowfield, Manchester, in April 1918, but 

 later I rediscovered some o£ my older material containing the same 

 species from Gibside, Co. Durham, June 1916, and a single example 

 from the shore at G-range-over-Sands. Swanage, Dorsetshire, May 

 1918. 



This species comes nearest to C. luhhochi, from which it differs in 

 the large macrochaetae at each hind angle of mesonotum, the smaller 

 anterior submedian (found on 1-7 only), and the larger and differently 

 formed lateral macrochaetae of the tergites, the form of stylus, etc., and 

 chiefly in the very different type of cerci, the distal joints each having 

 the appearance of being composed of 3 subsegments. 



The larvae described as that of C. luhhocJci by Silvestri is referable 

 to this species. 



Camjpodea loallacei, sp. n.* 



This species closely resembles C. giardi Silv., and a detailed description is 

 unnecessary. The macrochaetae at hind angles of both meso- and metanotum 

 are longer (and more slender) compared with the postero-marginal series of 

 minor setae. The most careful research fails to show the presence of either 

 anterior or posterior submedian setae on the abdominal tergites. The apical 

 seta of stylus is furnished with 2-4 branches on the inner margin, and the sub- 

 apical seta is branched near middle. The long macrochaetae of the prothorax 

 and abdomen are much more regularly " feathered." Cerci with the distal 

 joiuts longer and more slender, about 07 as long as the body.

 and H. S. B.). Mr. Wallace suggested that the species was associated 



* I have pleasure in naming this species after my friend Mr. H. S. Wallace, F.E.S., who 

 dlBcovered the lirat example aod who has of late made many interesting Arthropod " finds."
