TRICHOTAESUS XYLOCOPJE DONN. 25 



cephalothorax, and Michael shows them spine-like, so that their 

 ii<»-ures probably represent a species different from that of Canestrini, 

 and which I find in the United States. I'he species of this genus feed 

 on a great variety of substances, perhaps favoring- dried fruits. 



Carpoglyphus passularum Hering-. (PI. V, fig. 40.) 



Cephalothorax with a pair of short frontal bristles, apparently a 

 little back from the front marg-in; four posterior bristles in a curved, 

 transverse row, none ver\' long; a humeral bristle each side, with a 

 short one near by; two submedian pairs of short Ijristles on the dorsum; 

 two short ones on each posterior side margin; a short pair near tip 

 above, and three each side at tip. one pair ver}' short, the others more 

 than one-half length of body. Legs moderately long, tarsi long and 

 tapering; the sense hair on tarsi I and II tapers to tip; the l)ristle 

 above on penultimate joint is situated near the middle and not at tip, 

 and is very large and prominent, and longer than the tarsus in all 

 except the hind pair of legs. There are a number of hairs on legs, 

 but no spines; the hair near apex of tarsus is long and rather farther 

 from the tip than usual in tyroglyphids. 



Length, 0.40 to 0.50 mm. 



Specimens have been seen from Fresno, Cal., on figs; from St. 

 Anthony Park, Minn., on dried figs and apples; from Alban}^, N. Y., 

 on smoked ham. and on pollen of honey bees from Ohio. 



Genus TRICHOTARSUS Canestrini. 



No suture between cephalothorax and al)domen; mandibles chelate; 

 legs ending in distinct claws; male without suckers on hind tarsus; no 

 clavate or thickened hair on tarsi I and II; palpi not enlarged at tip; 

 cuticle not granulate; male without anal suckers; vulva of female 

 situated close to beak, between coxse I; hypopial nymphs found upon 

 bees, adults in nests of bees. 



Type. — T. OHinise, Dufour. 



The adult form is but little known; I have seen none from this 

 country; the hypopial nymphs are more common, and two forms 

 have been found in the United States. These agree well with the 

 European species, but as the adults are not known, their identification 

 is rather uncertain. They are of no economic value, and therefore I 

 shall simply list the two species as the European forms until such 

 time as mature specimens make possible a more exact identification 

 and satisfactory description. 



Trichotarsus xylocopae Donn, 



Prof. H. Osborn has recorded this European species as taken from 

 a California Xylocopn^ and sent to him by Mr. D. W. Coquillett. I 

 have not seen it, and possibly some other species was concerned.
