5. GRISEUS, Linn. (5). 



Abo : 3Iat/ 30th, 1885. 



[I confess that I omitted to consult the " Synopsis " of Dr. Puton, 

 but I now see that, under the generic name Elasmostethus, Cimex 

 griseus, Linn., is there given as a synonym of Cimex interstinctiis, 

 Linn. ; and Acanfhosoma griseum, var., Flor, is cited as distinct, under 

 the name of E. Fieheri, JakowL, without reference to Linne. The 

 points of difference noted are admittedly very small, except as to the 

 coloration of the antennae, and without an example before me I might 

 not have seen the validity of a species established mostly, as it ap- 

 peared to Flor, Fieber, and almost all other authors, on sexual or 

 colour variation ; still, as I said. I.e., I did not impugn the correctness 

 of Professor Eeuter's conclusion, or his determination of the species, 

 and we are all now greatly obliged by his present differential diagnoses 

 and figures. I said " the CJinocoris knoivn to us in Britain as CI. 

 griseus is one of the commonest ;" of course if this is CI. interstinctus, 

 it is the true griseus that is rare — mutatis mutandis. We have cer- 

 tainly the C. (jriseus of De Geer, of which he records the remarkable 

 care of the female for her young, which was independently confirmed 

 by Mr. E. Parfitt (Brit. Hem., p. 108) ; Kolenati, however (Mel. Ent., 

 iv, 61), in referring De Greer's C. hetulce to Acantliosoma interstinctum, 

 Linn., adds " excluso citato JAm^ei griseum \' yet while he (p. 57) 

 refers Linne's C. griseus to the genus Raphigaster, Lap., he still quotes 

 for it De Greer's fig. 9, t. 14 — the same that he does (p. 61) for inter- 

 stinctus ! — J. AV. D.]
