NEW AMERICAN ACARINA. 13 



and elavate ; abdomeu broadly elliptical, posterior margin crenulate, witb many 

 deep pits above and four rows of four large spatulate white hairs ; sides striate ; 

 venter smooth, legs short, barely nodulate, the femora thickened, other joints 

 slender, with a few simple hairs ; genital and anal apertures large and close 

 together. 



Sea Cliff, N. Y. Common in decaying fungi (Polyporm) ; a few 



specimens found under a piece of bark on the ground. 



C'arabodes apicalix nov. s]i. — Length .45 mm. Eeddish, legs yellowish ; 

 cephalothorax sub-triangular, anterior sides concave, posterior sides nearly 

 straight, slightly contracted behind, with a curved ridge each side from tip to 

 stigmata, several other smaller ridges, stigmata large, setse short, elavate ; two 

 stifl' elavate hairs near middle, and two fine hairs at tip ; abdomen truncate at 

 base, gradually growing wider, broadly rounded behind, a few irregular ridges 

 each side and above irregularly reticulate with ridges, each side a sub-median row 

 of three elavate hairs and about ten or twelve similar ones around the ti]i : venter 

 smooth, with two lines each side; genital aperture nearly circular, slightly sepa- 

 rated from the anal opening ; palpi more prominent than usual ; legs short, 

 slightly nodulate, the femora, especially femur I, quite long, the tarsal joints 

 much abbreviated, with very few hairs, except at tip. 



Sea Cliff, N. Y. Six specimens. 



C'Sirabodes obloiiga, nov. sp. — Length .55 mm. Black, legs yellowish ; 

 cephalothorax truncate in front, covering the pointed head, emarginate, and with 

 four curved stifi" bristles, surface granulate, sides consist of plate-like expansions, 

 a large bristle each side, and a smaller median pair; stigmata near margin, sette 

 moderate, elavate : abdomen truncate in front, over once and a half as long as 

 broad, not much broader in middle than at base, tip broadly rounded ; surface 

 deej)ly and finely pitted ; with aliout twenty-eight stiff bristles above, mostly 

 arranged in four rows, those near base i)roject forward over the cephalothorax, 

 the rest are directed toward the apex ; venter granulate, the coxae all united to 

 its surface; the genital opening nearly twice its length in front of the anal open- 

 ing ; legs short, barely nodulate, femora thickened, tibiaj pedicellate. 



Sea Cliff, N. Y, One specimen found under bark of a stump, the 

 bark was not yet dead nor loose. To the naked eye it looks much 

 like a small Scolytid beetle. This species should probably form a 

 new genus on account of the cephalic structure and of the widely 

 separated ventral apertures. 



]\OTHKUS Koch. 

 The cephalothorax is immovable ; the tectal plate and wings are 

 both absent ; the body is more or less rectangular and usually fur- 

 nished with some elavate hairs ; the legs are short and stout ; the 

 basal joints about equal in length and in thickness, furnished with 

 stiff, thickened, sometimes elavate hairs ; the tarsi are all furnislied 

 with three equal claw's; the genital and anal openings are very large, 

 and surrounded by several sutures.
