—22. 



Hypodhonius lanatus, Michael. Joiirn. Roy. Mici-osc. Soc, 



ser, ii, vol. v, p. 396. 



Average length about '33 mm. 



Average breadth about "18 mm. 



Average length of legs (first pair) about "1 2 mm. 



Average length of legs (second pah^) about "10 mm. 



Average length of legs (tMrd pair) about *11 mm. 



Average length of legs (fourth pair) about 'l-l mm. 



A species remarkable for its woolly hairs, its power 

 of erecting the spines on its back, and for its singular 

 mandibles. 



Colour rather light yellow-ochre. 



Texture dull, reticulated, slightly pulverescent. 



Cephalothorax small, irregularly reticulated. Ros- 

 trum blunt. Lamellae represented by two low, rough, 

 thick ridges extending far forward. Bostral, lamellar, 

 and interlamellar hairs, also a pair of hairs at the 

 anterior side of the pseudo- stigmata, and a pair of hairs 

 between these and the lamellar hairs all assuming the 

 condition of hunches of ivhite ivoolly substance. The 

 rostral hairs are far the largest of these, which is most 

 unusual. When these woolly hairs are examined with 

 a high power they are seen each to consist of a main 

 stem with a considerable number of branches or pinnje 

 arising from it, forming a sort of fine brush which 

 holds flocculent matter. Pseudo-stigmata small, 

 near the postero-lateral angles of the cephalothorax. 

 Pseudo-stigmatic organs long, almost straight, directed 

 backward and outward ; they have long rod-like 

 peduncles and fusiform heads which are woolly like the 

 before-mentioned hairs ; when cleaned the distinction 

 between head and peduncle is not apparent. Palpi 



* LarMtua, wool-bearing.
