the punctures very much larger, deeper and closer together, giving the thorax a 

 somewhat rugose appearance ; the whole insect is also somewhat larger. The (J diifera

 like the ^ , and the antennce entirely black (not fulvous) beneath, as in that species. 



In a lane near Q-uestling, Hastings, in October. I found the $

HETEBOPTERA. 



Peeiteechus geacilicoenis. 



Peritreclius prtcilicornis, Puton, Pet. Nouv. Ent., ii, 117 (1877) ; 

 Synops. Hem. Het. de Prance, 85, 2 (1878). 



Very like P. ge7iieulatus, Hahn, in form, size, and colour. Differs 

 in the antennae being very slender throughout, the 2nd and 3rd joints 

 cylindrical, not thickened upwards, and in all the tibife and tarsi 

 being testaceous. 



It resembles P. niihilus, Pall. {cf. E. M. M., xi, 2G7), in the 

 slender antennae, but they are finer than in that species, more especially 

 with reference to the 3rd joint. 



I have an example from Hastings, which I long since put aside as 

 distinct, but forgot it entirely, until reminded of it by Dr. Puton's 

 description of his new species, with which it agrees. Dr. Puton 

 writes that it does not occur in the Departments of Vosges or Nord 

 of France, but is found at Houen, and that it is not unlikely to inhabit 

 the South of England. 



LygcBus puncticeps, Thoms. (cf. E. M. M., xi, 267), is now re- 

 cognised as Pachymerus geniculatus, Hahn (Wanz., i, 68, t. x, fig. 41 

 [1831]), and this having priority, the specific name will have to be 

 adopted, vice puncticeps. Herrich-Schaffer led the way into error in 

 the index to the " Wanzenartigen Insecten," by putting ye«jcMZa^«<5, 

 Hahn, = »m5j7ms, Pali., and so it passed, until Thomson, finding there 

 were two allied species, referred one to nuhilus, Pall., and named the 

 other puncticeps, not knowing or not recognising that it was Hahn's 

 geniculatus. Peritrechus nuhilus,Yo\\enhoven (Hem. -Het. Neerlandica, 

 p. 46, pi. 6, fig. 6 [1878]), must be referred to P. geniculatus.
