The varying and in general irregular form of these protuberances seems 

 to me to justify the assumption, that they are composed of matter 

 sweated out of or secreted from the vulva; in one specimen, in which 

 I managed to separate them, there appeared beneath, close to the rima 

 genitalis, a rather small but deep fovea, broader behind and slightly 

 notched in the posterior margin. In other specimens, in which the 

 above-mentioned single or double protuberance is absent, the vulva 

 has the form of two rounded fovea? close to the rima genitalis, se- 

 parated by a more or less )(-shaped septum or interval, much as in 

 H. muscorum ?. 



The male of II. flavipes is easily distinguished from H. cupreus 

 by having the tooth on the femoral joint of the palpus bifid at the 

 apex , its posterior prong being considerably smaller than the other ; 

 the spine on the outer side of the tibial joint is shorter, curved 

 downwards, and almost -^-shaped; the lamina, broader at the base, 

 is of uniform breadth from about the middle to the rounded- extre- 

 mity; the tooth on the posterior part of the bulbus is curved down- 

 wards. The female's cephalothorax is without the deep transverse 

 depression behind the hindermost row of ej'es, which we observe in 

 cupreus j; the hairy clothing is destitute of metallic brightness. 

 In all the specimens of this species that I have seen, the vulva is 

 composed of two distinct, rounded or somewhat oblong, shallow fovea? 

 close to the rima genitalis.

Vid. preced. spec. , Attus cupreus Westr. — That H. flavipes is 

 included under Blackwall's Salt, cupreus, is evident from his descrip- 

 tion of the male's palpi, where it is stated that their femoral joint 

 "has a very large bifid protuberance on the under side" etc.
