rectilinear, or undulated scries. I hiive found them about the 

 uiiddle of May.

Feet six; trophi forming a capitate body; palpi conic, quadri- 

 articulatc ; an obtuse tube, subconic, advanced ; body soft.

 tant hairs; head whitish, somewhat rounded, [81] contracted, 

 at base and acute at tip ; palpi white, a little hairy, rather sur- 

 passing the tip of the head ; tcrgum with a deeper red eye on

Cabinet of the Academy. 



Of this species, I have found a specimen adhering near the base 

 of the palpi of an Ai-aiiea. 



The head-like process, is sometimes retracted so as to be not 

 prominent, but is not long withheld in this position. The body 

 is somewhat contractile, not perceptibly as regard its length, but 

 in its breadth, by an irregularly undulated motion of the edge. 



2. L. IIISPIDUS. — Body suboval ; head with a distinct neck; 

 palpi more robust at base ; feet elongated, much longer than the 

 body, filiform and furnished with numerous robust, incumbent, 

 flexible setoe, about twice the diameter of the leg in length. 



My Cabinet. 



I took no less than ten of these animals from a Phalanglum, to 

 which they adhered very strongly ; when feeding, they often are 

 supported only by the rostrum and palpi, the body and feet being 

 elevated so as to be sometimes perpendicular to the supporting 

 3urface. [82]
