186 AMERICAN HYMENOPTERA. 



(3.) S|>lieco«les seiiiicoloratiiK (Ckll.). 



Halicfns semicolordtux (!kll., Tr. Am. Ent. Soc, sxiv, 168, 9- — N. Mexico. 



A curious little species, with a narrow abdomen like the very 

 nuich larger S. kincaidii. 



(4.) Spliecotles kiietschi n. sp. 9 • — Length about 7h mm., entirely hhtck. 

 except that flie tibiie are dark sepia brown, the tarsi liqhfer brown, — one might say dull 

 ferruginous, and the shini)ig hind margins of the first three abdominal segments are 

 broadly castaneous. Antenna wholly dark, the flagellum with the feeblest brown 

 tint beneath; wings smoky, the nervures and stigma fuscous; tegulae piceous. 

 Head transversely oval, facial quadrangle much broader than long; labial palpi 

 with the first joint longest, the last three quite short and subequal ; mandibles 

 bifid ; mesothorax tolerably siiiny, with a slight median carina, and very large 

 well -separated punctures; base and sides of metathorax irregularly reticulated 

 with raised lines; abdomen with sparse but quite strong punctures; apex with 

 pale brownish hair; hind spur of hind tibia minutely ciliate. 



% . Similar, except in the ordinary sexual ciiaracters. Flagelhim only faintly 

 brown beneath. Nervures and stigma piceous. Legs black; the tarsi faintly 

 brownish. (Abdomen lost in the only % before me). 



Hab. — Terra Cotta, Illinois (Robert Kuetsch). On flowers of 

 goldeurod, the 1 August 25, the 5 September 5, 1897. 



Differs from S. smilacince Rob., in the larger size, color of legs 

 and antennae, and punctures of abdomen. 



(5.) C'allaiidrena (n. g.) maiiif'esta (Fox). 



Paniirgus manifestns Fox, Pr. Cal. Ac. Sci., Ser. 2, Vol. iv, p. 113, 9 . '^ • — 

 L. California. 



Mr. Fox sends me types of both sexes. Superficially the insect 

 resembles Rhophites, but the mouth-parts are entirely different. 

 Labial palpi {1 ) formed like those of Andrena pulchella, but 

 shorter, with the penultimate joint much shorter than the last, 

 whereas in pulchella it is very little shorter. The maxillary palpi 

 are also of the type of pulchella, but shorter, with the penultimate 

 joint very short. The eyes in both sexes are of a lilac color, perhaps 

 due to soaking in alcohol. Stigma small, as in pulchella. Abdomen 

 very like that of pulchella. Face-marks of both sexes much as in 

 % pulchella, light yellow ; clypeus with sparse small punctures in 

 9 , large and much closer one in S . Wings quite dark. 



Callandrena is the extreme end of the line which diverges froiu 

 typical Andrena in such forms as A. pulchella, and therefore has 

 no particular connection with Parandrena, the two submarginals 

 notwithstanding. It is readily known by the yellow face-marks in 

 both sexes, the small stigma, the palpi as described and the venation.
