120 COREINA. 



Not rare. Darenth, Folkestone, on thistles by the roadside, in 

 July ; "Weybridge, by sweeping grasses, in August ; Eltham, in 

 moss on the ground, August. 



The chief points of difference between C. hirticornis, Tab., and 

 C. pilicornis, Klug, according to Flor, are, that the former is " long- 

 haired, the head on the upperside with prominent tubercles between 

 the granules ; the side margins of the pronotum with strong, 

 pointed teeth, the last on the hinder angles not, or very little, larger 

 than the rest." The latter " is short-haired ; the head on the upper- 

 side without tubercles ; the teeth on the side margins of the^ro- 

 notum small, the last on the hinder angles perceptibly the largest." 



Fieber says of C. Mrticornis, " Hinder thighs with 5 spines, the 

 last and before the middle small" (the presence of the hinder 

 smaller spines we do not find to be constant). Of C. pilicornis he 

 says, "Hinder thighs with 2 strong spines and 1 small middle 

 spine." But Flor says that in both species the hinder thighs are 

 toothed exactly alike. 



The synonymy is extremely confused. Flor describes both 

 C. Mrticornis, Fab., and C. pilicornis , Klug ; yet he says of the former, 

 " This species has very great similarity with the latter, and it is 

 possible that a large number of examples of both species would 

 exhibit transitional characters and make their union necessary." 



Stein, in the Berlin ' Ent. Zeit.' for 1860, not only amalgamates the 

 two species, but gives them as synonymous with Oimex denticulatm, 

 Scop., Acanthia denticulata, Rossi ; Coreus denticulatus, Wolff; and 

 Coreus scabricornis, Panz., attributing their differences to climatic 

 influences over a wide geographical range. 



Eieber, on the other hand, has not only kept all as distinct species, 

 but has even placed Cimex denticulatus, Scop., in a new genus 

 (Bothrostethus) . 



Among this conflict of opinions, and being without specimens of 

 the species referred to, we bejieve we have not erred in uniting 

 C. hirticornis and C. pilicornis. 



Genus 6. SPATHOCERA, Stein. 



Head finely granulated above and beneath ; Crown quadrangular, 

 convex, the sides in front produced into a short, sharp spine, within 

 which the tubercles of the antennae are plainly visible ; behind the
