HEMIPTERA HETEROPTEEA. OF CErLON. Ill 



Mr. G-reen's collection contained specimens of two species of 

 Crimia, apparently distinct from any of the foregoing, but which 

 I do not describe because they are immature. 



ClMICID^. 

 *ClMEX LECTULAEIUS. 



Cimex lectularius, Linn. Syst. Nat. i. p. 441, n. I (1758). 



A cosmopolitan species ; but there is some reason to believe 

 that it was originally confined to Africa, where it has always been 

 known by the name of Bug, or at least to the tropical and sub- 

 tropical regions of the Old World, and that it was introduced into 

 America by slave-ships, and brought thence to Northern Europe. 

 It was known to Aristotle as occurring in the Mediterranean 

 Region in his time ; but I believe the earliest recorded date of its 

 having been observed in England is 1503. 



JN'evertheless Mr. CO. Waterhouse informs me that an insect 

 which cannot be distinguished from this is found in the Lower 

 Tertiaries of Scotland ; but even granting that the identification 

 is correct, this insect, like the rest of the then existing fauna and 

 flora, would almost certainly have been driven out or extermi- 

 nated by the Glacial Period ; and we cannot therefore admit that 

 the observation proves more than that the insect may have been an 

 inhabitant of Scotland at some former period. 



E-EDTJVIID^. 



*tLESTOMEEus HOEEiDus, sp. n. (Plate lY. fig. 16.) 



Long. corp. 20 millim. 



Blue-black, sparingly clothed with long bristles ; extremities 

 of tibiae and tarsi showing a tendency to shade into rufo-testa- 

 ceous ; wings rudimentary ; inner portion of tegmina testaceous ; 

 abdomen with testaceous marginal spots on the front of each 

 segment both above and below ; front femora thickened ; vertex 

 grooved ; frontal lobe of thorax with a shallow groove at the 

 back and with three shallow oblique depressions on each side ; 

 hinder lobe not grooved. 



The type is not quite mature. 



Allied to L. affinis, Serv. ; but this is a shorter -and broader 

 insect, with the abdominal margins unspotted. 



Except that the legs are black, it has likewise much resemblance
