38 THE extojiologist's recokd . 



Fnniiica nij'a, /•'. pratt'iisis, Mi/niiica lavrinudis and Lasiiis t'ldiffinnxHs. 



VilujthorKfi bifasciattiii, F. (=Caiiiaro)iutiis cinncanaptcrus, Kir.). — 

 Douglas (loc. rit.) says " Caniarowitiiscinnamaptenis, which in both sexes 

 is very like a small I'onnica rufa .... is constantly found on 

 trees, Ac, in company with that ant." Wasmann (loc. cit.,]). 182) records 

 it with Formica iiratcnsis as well as 7*'. riifa. 



Pilophorui^ perplcxna, D. and Sc. — -Norman [Knt. Mo. Ma;/., 1878-79, 

 p. 253) says " I saw some larvte of this species running up and down 

 the stem of an apple tree among a number of Formica /W.srrt." Was- 

 mann {loc. cit., p. 183) in quoting this record, which he attributes to 

 Douglas in error, suggests that I.asins nii/rr, L., was the ant he found 

 them with and not F. fiisca. I have taken it at Chiddingfold in 1898 run- 

 ning about in the "runs" and on the trunk of an oak stump inhabited 

 by Lasiiis fiili(/inosi(s. On September 18th, 1901, I took several 

 specimens by beating aspens swarming with Lasiii-'i niijcr at Bexley. 



Si/stellonotKs triijiittatuR, L. — Douglas {Iw. cit., 1865-66, p. 30) records 

 the capture of this species (J s, $ s, and pup*) in numbers with 

 Formica fiisca at Weybridge. Saunders {Fnt. Mo. Mai/., 1892, p. 290) 

 records it freely running amongst a colony of T,asins nit/cr at Chobham. 

 Wasmann {loc. cit., p. 183) gives the host as Lasiittinii/cr, suggests that 

 Douglas' record referred to L. ni<jcr and not F. fuaca, and points out 

 that the male is neither so like an ant, nor so truly myrmecophilous 

 as the larvte and females. 



Nabiti latircjitris, Boh. — Sharp {loc. cit., pt. ii., p. 556) figures the 

 young of this bug and writes : " One of our indigenous Nabides is of great 

 interest from the curious resemblance it has to an ant. The likeness 

 is brought about by the sides of the base of the abdomen being very 

 pallid in colour, except a dark mark in the middle ; this mark is in 

 shape like the pedicel of an ant. Viewed in profile it is found that on 

 the base of the abdomen there is an elevation like the " scale " in this 

 position in ants, and that the abdomen is extremely ant-like in form. 

 This resemblance is quite parallel with that of an Orthopteron to an 

 ant (see, vol. v., p. 323) ; the insect is by no means uncommon, and 

 it is strange that this curious case of resemblance should hitherto have 

 escaped notice. The bug runs about on plants and fiowers, and is 

 frequently met in company with ants, but we do not know whether it 

 preys on them. Not the least remarkable of the facts connected with 

 this insect is that the resemblance is confined to the earlier instars, 

 the adult bug not being like an ant." Wasmann records the larva 

 (loc. cit., p. 181) with Lasiiis fiilii/iitnsiis in Holland, and with a Mi/rmica 

 species in France. 



Dictijoiiota craasicornis, Fall. — Mr. Morley took a specimen of this 

 insect in the nest of Mi/rmica rubra at Covebiltre Broad, Suftblk. 



Sti/i/ntis pcdcstris, Fall. — Mr. Keys took a specimen of this bug 

 in the midst of the ants in a nest of Mi/rmica ficabrinodis at Plymouth. 



Trojiistet/nis lioloscriccus, Schultz. — Saunders (h>c. cit., p. 87) says that 

 Dr. Puton records this species with ants, but he is not aware of its 

 having been captured under such circumstances in this country. Mr. 

 Jennings tells me he took it in an ants' nest at Dorking in 1897. 



Homoptera. — C'ercopid.e. — TypJdocyba cratactji, Douglas. — I took a 

 young larva and later the perfect insect in the nest of Lasiusfidii/inosu.'i 

 at Oxshott. It is perhaps worth mentioning that Belt has recorded 

 the fact that in Nicaragua the larvfr of c«M-tain Jlnninptrra were assidu-
