190 Mr. W. S. Dallas's Notice 



ing. Abdomen convex, punctured with black, the punctures very 

 close together towards the margins, thus forming a broad cloudy 

 line down each side within the line of stigmata ; the base of the 

 second segment, and a large spot in the centre of the fifth and 

 sixth segments, black. Breast and underside of head concolorous 

 with the abdomen. Legs pale testaceous, with distinct pitchy 

 punctures ; those on the thighs much larger than those on the 

 tibiae, the apex of the latter and the tarsi tinted with ferruginous. 

 Antennae with the two basal joints (which are all that exist in the 

 specimen) pale testaceous ; rostrum of the same colour, with the 

 apex pitchy black. 



The fourth species appears to be nearly allied to Cimex ritjipes, 

 Linn., which forms the type of the genus Cimex, as restricted by 

 Amyot and Serville. It appears to agree in most of its characters 

 with their description of that genus, but is distinguished from all 

 the other Venlalom'ides by its possessing only two joints in the 

 tarsi. It will probably be found to form the type of a distinct 

 sub- genus; but as the specimen before me is very much muti- 

 lated, it will be better for the present to place it provisionally in 

 the genus Cimex.* 



Sp. 5. Cimex? Boulanicus. (Plate XIX. fig. 4.) 



C. fuscus, rugoso-punctatus, angulis lateralibus thoracis in 



processum magnum latum 5-dentatum productis j. 

 Long. lin. 9g, hemelytrorum membrana inclusa. 



Body ovate. Above brown, obscure, tliickly and strongly 

 rugose-punctate. Head rather thickly punctured, nearly as broad 

 in front as behind, and with the anterior margin strongly notched ; 

 slightly wrinkled posteriorly. Eyes pitchy ; ocelli yellowish. 

 Thorax with the enlarged lateral angles considerably directed 

 forwards, with five teeth at their apex, of which the third and 

 fourth from the front are rounded, the others acute. A strong 

 spine at each anterior angle of the thorax, immediately behind 

 the eyes, and the antero-lateral margins are strongly serrated. 

 Scutellum rather elongated, narrower towards the apex, which is 

 less punctured than the rest of the body, and margined with 

 yellowish. Elytra rather paler than the rest of the surface, 



* MM. Amyot and Serville place this genus amongst the Rhaphigastrides, 

 there being a very rudimentary spine at the base of the abdomen ; but although 

 the present species possesses the slight keel on the sternum, which might appear 

 to refer it to the following group, yet as I can discover no trace of a ventral spine, 

 I have thought it better to place it in the Pentatomides,
