Anthidium pecosense, n. sp. 



Male; length about 11 mm., stout and compact; pubescence 

 white on pleura, cheeks and face below antennae, but ful- 

 vous on upper part of head and thorax ; hair quite dense 

 over clypeus ; clypeus, lateral face-marks, mandibles ex- 

 cept tips, and small spots above eyes, lemon yellow; cly- 

 peus with two dusky dots near its upper margin ; mandibles, 

 comparatively narrow, second tooth small but pointed; 

 antennae entirely black ; thorax black with the tubercles,, 

 a bent stripe on antero-lateral corner of mesothorax, and 

 two lines on scutellum, yellow : tegulae black with a large 

 pale yellow mark ; wings dusky ; femora black, with more 

 or less of a yellow stripe beneath (best developed on the 

 anterior ones, but obscured by hair), and the middle and 

 posterior ones with very small apical (knee) spots; tibiae 

 broadly yellow on the outer side ; basal joint of tarsi yel- 

 low, the other joints ferruginous; abdomen with the bands, 

 bright lemon-yellow, that on the first divided into four 

 spots, the median spots subquadrate ; band on second di- 

 Added in the middle and squarely notched laterally, on third 

 divided in middle and with small lateral notches, on fourth 

 and fifth emarginate only in the middle, and not notched 

 laterally; sixth almost all yellow, but emarginate with 

 black in middle ; apical segment with two yellow spots ; lat- 

 eral apical lobes broad, median process long, lateral teeth 

 on sixth segment rather short ; venter black. 



Hab. — Pecos, New Mexico, one at flowers of Heracleum lana- 

 tum, June 21, 1903. (Cockerell). The apex of the abdomen 

 is of the same type as A. mormonum, from which it is easily 

 distinguished by the fulvous hair of head and thorax. From 

 A. poudreum, Titus (misprinted pondreum in original 

 description). A. pecosense differs by having the ventral 

 segments of abdomen thickly pubescent right across, fe- 

 mora and tibiae with white hair, dorsum of thorax with 

 abundant fulvous hair, no dots before the imes on scutel- 

 lum, all the femora with yellow stripes, band on first ab- 

 dominal segment broken into spots. 



Anthidium bernardinum, n. sp. 



Male ; length about 13 mm., general appearance of A. tricuspi- 

 dum, but differing in many details, and especially in the 

 apex of the abdomen, the lobes of which are much shorter, 

 broader and more rounded, and yellow with dark brown 

 margins, the median spine also being dark brown. The 

 real affinity of the insect is with A. pecosense, but it is. 

 larger, and very different in its deep orange markings;
