190 LIPURA. 



This species is not the P. ambulans of Linnseus. 

 Both in the ' Faun. Suec' and in the ' Sjs. JSTat.' that 

 species is described as having long caudal appendages. 

 It is probably a Cajnpodea. 



Lipura Burmeisteri, Lubbock. 

 Plate XLIV. 



White. Skin granular, sparsely covered with short, 

 stiflp hairs ; antennfB clubbed. 



Head large. Prothorax of moderate size. First 

 three abdominal segments rather shorter and wider 

 than the posterior thoracic ; fourth abdominal segment 

 rather narrower than the preceding ; fifth still nar- 

 rower, semicircular, rounded behind ; sixth tapering, 

 terminating in two strong, upturned hooks. 



Length -1 of an inch. 



The mandibles have four teeth. The maxillae are 

 delicate and elongated. 



The post-antennal organ (PL LXV, fig. 16) consists 

 of two rows of oval prominences, situated transversely 

 in a long hollow at the sides of the head. The rows are 

 not contiguous. The prominences are attached so close 

 to one another that they overlap in their broadest parts. 



The granules of the skin are largest on the back, 

 and especially at the anterior margin of each segment ; 

 they diminish gradually in size posteriorly. Those on 

 the intersegmental membrane are also small. The 

 different sizes are not intermixed, but occupy definite 

 areas. Those on the legs are of the lesser kind. 



The legs are short. The feet are all alike. The 

 upper claw is strong, the lower one is almost reduced 

 to a mere hair. There are no tenent hairs. 



I found this species in considerable numbers under 

 a board during the month of December. 



England.
