Rev. L. Jenyns on three undescribed species of Cimex. 243 



punctures and the degree of pubescence, are similar in the 

 two species. 



C. Hirundinis, Nob. 



This species is rather less than the C. columbarius, and in 

 respect to form, different from both that and the C. lectularius. 

 The antenn(B are comparatively short, and the third joint is 

 scarcely, if at all, longer than the fourth. The eyes are not 

 so prominent. The thorax is much less hollowed out in front, 

 the anterior angles but little produced, and the sides scarcely 

 at all reflexed. The scutellum is wider at the base or more 

 transverse, and does not project so far backwards. The elytra 

 are less coarsely punctured. The abdomen is not so broad, 

 and more rounded at the apex ; the sides regularly curved. 

 The whole insect is more pubescent. The colour is ferrugi- 

 nous inclining to testaceous, darker than in the common bed- 

 bug ; and the head and thorax are much clouded with fuscous. 

 In one specimen the legs are spotted, at or near the joints, 

 with this last colour. There are also some fuscous spots on 

 the abdomen. 



The young, or pupce, have the abdomen much narrower 

 than the perfect insect, inclining to oblong. 



C. Pipistrelli, Nob. 



The antennas of this species are of an intermediate length 

 between those of the C. lectularius and those of the C. colum- 

 barius ; and the third joint is obviously longer than the fourth. 

 The eyes are prominent. The thorax has a moderately deep 

 excavation in front, and the sides are partially reflexed. The 

 abdomen is narrower than in either of the above-named spe- 

 cies, and much more attenuated posteriorly, the greatest 

 breadth being rather before the middle. The thighs are more 

 incrassated. The whole insect is very pubescent, approaching 

 to hispid ; and rather coarsely punctured. The colour is dark 

 ferruginous-ochre, glistening with a faint metallic or sub- 

 aeneous hue, not perceptible in any of the other species. The 

 legs and antennae are a shade paler than the abdomen, and as 

 well as this last, without spots. 



I shall annex a synoptic view of the specific characters of
