THE EUROPEAN SPECIES of the GENUS CLINOCORIS, HAHN, STAL. 



BY PROF. O. M, EEUTER. 



In the Ent. Mo. Mag., xxi, p. 276, Mr. Douglas has a note con- 

 cerning Clinocoris (/7'iseus and inter stinctus, in which the short report 

 in the "Wiener ent. Zeitung" is accounted to be my exposition of 

 the synonymy of these species in the " Revue mensuelle d'Entomol." 

 Mr. Douglas, however, leaves it to be inferred that he is not aware of 

 any structural differences between the two species, and says, he does 

 not know how I have arrived at my conclusion of the reality of Linne's 

 two species. But the differences between CI. inte^^sfinctus, L., and 

 griseus, L. (= Fieheri, Jak.), are already well pointed out in Puton's 

 well-known " Synopsis d' Hemipteres de France " (ii, p. 76) ;* yet in 

 copying the descriptions by Linne, Mr. Douglas has left out just the 

 most essential character of griseus, which also undoubtedly shows that 

 this species is identical with Jakowleff's CI. Fieheri. Linne says of 

 this species : " Antenncd fusco-nigricantes,'' which character always be- 

 longs to the male of this species, but never to CI. inter stinctus, of 

 which it is said, " omnibus partihus pallidior." The different colour 

 of the dorsum, assigned by Linne, Mr. Douglas has observed, but this 

 character distinguishes properly the females only, while the male also 

 of interstincius has the dorsum black as far as the apex. 



As, however, it may not be unwelcome for British Hemipterists 

 to know the essential differences between these species, I give a Sy- 

 nopsis of all the European (and Siberian) species of Clinocoris known 

 by me, one of these hitherto undescribed. To this genus I also join 

 the Cimex ferrugatus, Fabr., which differs chiefly by the long-produced 

 lateral angles of the pronotum ; Stal was also of the same opinion. 

 Many exotic species, and also CI. dorsalis, Jak., make an evident 

 transition to the genus formed iov ferrugatus, and which, quite erro- 

 neously, has been named Sastragala. (The true genus Sastragala w^as 

 created by Amyot and Serville for a species from India, >S'. uniguttata, 

 Don., w^hich forms a genus quite distinct from the European, for which 

 latter the name has been wrongly employed by recent authors). 



Synopsis Specieeum Eueop^aeum G-eneeis Clinocoris, Hahn, Stal. 

 1 (4) Dorsum abdominis testaceum vel interdum piceum, utrinque testaceo-macula- 

 tum. Connexivum solum angulis apicalibus segmentorum uigris. Pronotum 

 angulis lateralibus fortiter productis (figs, h et i), apicalibus denticulo parvo 

 transversali instructis. 



* From the descriptions given byPuton, Mr Douglas might have found that it is iaierstinclus 

 and not griseus, which is one of the commonest Heniiptera in England, and that it is griseus (= 

 Ficberi), which here and there might possibly be mixed with the former in collections.
