It is Dr L. Koch of Niirnberg, to whom science is indebted for 

 the interesting and startling discovery, that C. Koch's Dendryph. 

 lencomelas is the female to his Philia sanguinolenta. Dr Koch com- 

 municated this his discovery to me as early as 1862, and described 

 e. g. how he had found in one and the same nest "Ph. sanguino- 

 lenta" together with "D. leucomelas". Conf. Sim., Re'vis. d. Attidse, 

 p. 191 (G7). — Simon considers D. xanthomelas C. Koch and D. dor- 

 satus id. as belonging to the same species as D. leucomelas, and in 

 this he is probably right. (Attus leucomelas Rossi ') is an entirely dif- 

 ferent species). The male of D. dorsatus Sim., described by Simon, 

 is a cf jun.: I myself possess a similar undeveloped male, the palpi 

 of which present exactly the same appearance as the figure given by 

 Simon in his Monogr. d. Attides (PI. 6 (II), fig. 13) of the palpi of 

 his "D. bivittatus cf", and which figure appears to be intended to 

 show the peculiarities in the construction of the palpi, on which 

 Simon had founded the genus Dendryphantes (C. Koch), Sim., which is 

 by no means the same as Dendryphantes (C. Koch), Ohi,. et Thor. 

 Conf. Thor., On Eur. Spid., p. 215. In his Re'vis. d. Attidse, p. 134 

 (40), Simon has reunited Dendryphantes Sim. with Attus Sim. 



The male or "Philia sanguinolenta' varies considerably in size, 

 colour of the legs etc.; south-European specimens have usually on 

 the cephalothorax two longitudinal bands formed of white hair, though 

 these are frequently wanting. Conf. Sim., Re'vis. d. Attidse, p. 137 (13). 

 The spider which Simon in Monogr. d. Att. described as the female 

 to his A. sanguinolentus , probably belongs to the to me unknown 

 Ph. hcemorrhoica C. Koch. Vid. Sim. , Rev. d. Att., p. 191 (67). The 

 male of this PJrilaus hcemorrhoicus is said by Simon to differ from his 

 A. sanguinolentus by having a black belly and a shorter tarsal joint 

 (lamina) of the palpi: in the last-named species this joint is at least 

 three times as long as it is broad, and the belly is red. — Philia 

 sdigera Dolesch. 2 ) is perhaps not different from "Ph. sanguinolenta".
