ARACHNOIDEA, 



CASE 

 IX. 



This is perhaps the Acarus phalangioides of Degeer, which 

 occurs under the bark of trees in the forest of Ardennes. It is 

 black, with a scarlet stripe down the back, and scarlet legs and 

 eye spots. 



No. 6. Rhyncholophus major {Du^ 

 of ditto. 



Ann. Sc. Nal. 1834). — 6. Magnified figure 



Rhyncholophus major. Copied from Duges' figure. 



M. Duges places this among the Tetranychi. It seems to us 

 more allied to this form, and perhaps a sex of one of the long- 

 legged species. Black, with red on the back. 



Genus Smaridia {Duges). 



M. Duges establishes this genus chiefly on the extensibility of 

 the beak, in the single species on which he found this character. 

 As this, however, requires pressure to be observed, 

 and as without subjecting all the other species to the 

 same test, to see how it affects them, it can scarcely 

 be assumed to be peculiar to it, we do not think it 

 is a character that can be trusted to alone. There 

 is another minor character that is present in Duges' 

 species that might do to establish a section upon, 

 namely, that instead of hairs the body is covered with 

 papillae. In Pachygnathus velatus he describes the 



Smaridia papillosn, 



Rostrum. Copied 



from Duges.
