TYROGLYPHUS TERMINALIS IST. SP. 17 



penultimate joint about as long as tarsus; third and fourth joints of 

 hind legs more than twice as long as broad; in the male the suckers on 

 hind tarsi (PI. lY, fig. 35) are more than twice their diameter apart 

 and nearh' as close to each end of joint as to each other. (Vulva and 

 anal suckers, PI. IV, fig. 33; male aperture, PI. IV, tig. M.) 



Length, 0.35 to 0.40 mm. 



Specimens from Columbia, Pa., with Lecaniuni on plum; also with 

 03'ster-shell scale on osage orange (probably from Missouri), with mealy 

 bug on guava at Rock Ledge, Fla. , and on orange leaves at Sanf ord, Fla. 



This species is very close to T. Untneri Osb., and might have been 

 considered as only a variation of that species but for the totally difl'er- 

 ent haljitat. The legs are rather more slender, but the hind tarsi are 

 no longer, and the hair at the tip of the penultimate joint is not as 

 long as in T. l!ntn<:r!, nor as heavy. 



Tyroglyphus breviceps n. sp. (PI. IV, fig. 30). 



Cephalothorax ver}^ short, in proportion to the length of the body; 

 four rather long, subequal bristles above in a transverse row, and a 

 short pair in front over mandibles; two moderately long humeral bris- 

 tles; two submedian pairs on the dorsum, the basal pair short, the 

 other scarcely as long as abdomen ; six bristles each side and near tip, 

 rathei' widely separated at base, from two-thirds to fully the length 

 of the body; a short pair below near anus; tarsus aV)out twice as long 

 as preceding joint, the bristle at tip of latter as long as tarsus on the 

 front legs (PI. IV, fig. 32), and three-fourths as long on the hind legs; 

 each tarsus with a fine bristle beneath near middle; hind tarsus (PI. 

 IV, fig. 31), with apical hair not one-half the length of tarsus; the 

 third and fourth joints in hind leg not twice as long as broad. 



Length, 0.35 to 0.50 mm. 



The hairs are a little shorter than in T. arnericanus and the legs 

 rather stouter, and especially so in the front legs of the male. 



Specimens from Victoria, Tex., taken from dead larvae of the cotton 

 boll weevil. 



Tyroglyphus terminalis n. sp. 



Cephalothorax with four bristles in a transverse row, the outer pair 

 nearly twice as long as the inner pair, a pair of short bristles on ante- 

 rior margin; two humeral bristles, about two-thirds the width of the 

 body, two pairs of bristles above on abdomen, and five pairs near tip, 

 all about one-half the length of the abdomen except one pair each side 

 near tip, which are about as long as the abdomen; all are simple. 

 Legs rather stout, especially the anterior pair (PI. Ill, fig. 26), the 

 bristles stout, and many of those on the tarsi are spine-like; tarsus I 

 is not twice the length of the penultimate joint, while the hind tarsi 

 (PI. Ill, fig. 27) are about as long as two preceding joints together;
