ANOPLURORUM BRITANNIA. 231 



densely fringed with stiff hairs; legs pale chestnut, the 

 anterior pair shorter than the following ; femora large, nearly 

 orbicular, convolute ; tibiae short and thick, posterior pair 

 longest, femora oblong, the inferior margin reflexed ; tibiae 

 curved and notched; tarsi long, the first joint short, the 

 second very long, with a prominent involute pulvillus ; 

 ungues large, sinuated near the apex, slightly curved. 

 Length 1 !. 



Infests the Common Swift (Cypselus apus). Buffon in 

 his History of Birds alludes to this insect, when describing 

 the Swift, but without giving it any particular designation. 

 Professor Otto, however, in his Translation of the above 

 work, has minutely described it, as I am informed. Nitzsch 

 had attached the MS. name of Pulicare to this species, 

 and placed it in his Sub-genus Menopon, from which I have 

 ventured to remove it, as I feel convinced he would not 

 long have allowed it himself to remain in a group, from 

 which it differed in several particulars. Many of its charac- 

 ters approach much nearer to Trinoton, and in general 

 appearance there is a strong resemblance to Laemobothrion. 

 In raising it to the rank of a Sub-genus, I feel proud 

 in thus being able to add my mead of gratitude to departed 

 worth, by attaching to it the name of the late distinguished 

 Professor of Natural History in the University of Halle, 

 and while paying posthumous honour to one individual, I 

 have equal gratification in marking my admiration of the 

 labours of his successor, Dr. Burmeister, one of the most 

 zealous and able Entomologists of Germany. Should I be 

 accused of bad taste in deriving both generic and specific 

 names from those of individuals, I shall not attempt to ex- 

 culpate myself, but point to the Rafflesia Arnoldi, by 

 which (had there been no other means) the names of two 

 lamented cultivators of science are rescued from oblivion.*
