 ond transverso-cubital vein. 



Clypeus of $ yellow; J with apical plate 



narrow, veins black .... clypealus. 



Both $ and ? entirely black; ? with 



apical plate fairly broad, veins pale 



utrkcps. 



First recurrent vein received by the second 



subniarginal cell some distance from the 



second transverseo-cubital vein. 



Abdominal bands entire. 



Postscutellum white . . sctitellaris $ 

 Postscutellum black .... cinctus. 

 Abdominal bands interrupted. 



Abdomen with four yellow bands, the 

 first two broadly interrupted on the 



disc visaliensts ^ 



Abdomen with five yellow bands, broadly 

 interrupted laterally narrowly so in the 

 middle anthidius $ 



1. Calliopsis clypeatus Cress. — St. He- 

 lena, Cal., March 26. Fourteen specimens 

 collected upon Brassica campestris. The J 

 differs from (J in being a little larger, of a 

 duller black color, and having no yellow on 

 the clypeus. Previously recorded from Col- 

 orado. 



2. Calliopsis atiiceps Cress. — Berkeley, 

 Cal., March and April. Many specimens 

 collected upon Brassica campestris and Ra- 

 nunculus californicus. The female resembles 

 the male very closely. They vary in length 

 from 6 to 8.5 mm. 



3. Calliopsis sciifellaris n. sp. — <J . 7.5 

 to8 mm. Black with yellow markings; post- 

 scutellum white. Head black, very finely but 

 not closely punctured, uniformly clothed 

 with white pubescence; spot between anten- 

 nae and face beneath — except two small spots 

 on the clypeus, one in the suture on each 

 side of the clypeus, and one on the labrum — 



sides of the face extending up almost as high 

 as the anterior ocellu.s, and mandibles except 

 i\\->s, yellowish lukiie. Antennae white with 

 a dark line above which toward the tips 

 spreads out covering nearly the whole of the 

 last three joints. Thorax black, densely 

 punctured, clothed with rather dense white 

 pubescence, sometimes tinged with yellowish 

 above, sparse on disc of metathorax ; tuber- 

 cles except sometimes a brown spot on the 

 middle, tegulae except an irregular brown 

 patch near base, postscutellum and narrow 

 line on scutellum, white. Wings hyaline, 

 veins pale brown. Legs yellow, coxae and 

 trochanters except at joints, and femora at 

 base, and beneath except at apex, a large 

 spot on all the tibiae beneath and a small 

 one on the posterior tibiae above (sometimes 

 indi.stinct) and sometimes the apical joints 

 of the posterior tarsi black; pubescence 

 on the legs white. Abdomen black, with 

 broad yellowish or whitish bands on seg- 

 ments 1-5, narrowed slightly on the middle 

 and more or less notched with black on the 

 lateral apical portions; pubescence thin 

 and whitish, becoming longer and denser 

 toward apex. Venter black. 



Habitat. Fresno, Cal. (H. O. Wood- 

 worth), May 4-9. Seven males, collected 

 upon Melilotus indica. 



4. Calliopsis ductus Cress. — Tehachapi, 

 Cal. (II. O. Woodw^orth), May 12. One 

 male. Previously recorded from Nevada. 



5. Calliopsis visaliensis n. sp. — $. 7.5 

 mm. Black, abdomen with four yellow 

 bands, the first two broadly interrupted on 

 disc. Head black, finely and densely punc- 

 tured on vertex, thinly and coarsely so on 

 clypeus; clothed with whitish pubescence, 

 very thin on clypeus ; the lower lateral cor- 

 ners of the clypeus, a small spot on the mid- 

 dle near the apex, three spots just above the 

 clypeus and the lower corners of the face 

 yellow ; mandibles black at tips and brownish 

 or yellowish at base. Antennae black, be- 

 coming pale brown toward apex beneath. 

 Thorax piceous-black with white pubescence
