512 ANTHOCOUINA. 



young, or pupce, have the abdomen much narrower than the perfect 

 insect, inclining to oblong. 



" Swarming in martins' nests in Cambridgeshire." 



We saw specimens of this species in the collection of the late Mr. 

 John Curtis, found in martins' nests at Tunbridge Wells. The nar- 

 rower form and stronger pubescence were in striking contrast with 

 A. lectularia. 



Species 4. — Acanthia Pipistrelli. 



CiMEx PiPisTKELLi, Jenpis, All. N. H. iii, 243, 244, pi. v, fig. 3 (1839). 



" Ferrugineo-ochraceiis, nitidus ; thorace profunde emarginato, lateri- 

 bus paulo reflexis ; abdomine ovato, postice attenuate ; an- 

 tennis articulo tertio quarto longiore. 

 " Long. 2 lin. Hab. in Vespertilione Pipistrello. 



" The antennse of this species are of an intermediate length between 

 those of the C. lectularius and those of the G. columharius ; and the 

 3rd joint is obviously longer than the 4th. The eyes are promi- 

 nent. 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 species, and much more attenuated posteriorly, 

 the greatest breath 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 ferru- 

 ginous-ochre, glistening with a faint metallic or sub-oeneous 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 have seen but one specimen, taken in Cambridgeshire."
