Mesonotum dull black, the submedian lines sparsely haired. Scutel- 

 lum and postscutellum dark reddish brown. 



Abdomen nearly naked, reddish brown, darker basally ; genitalia 

 dark brown. Genitalia; basal clasp segment short, stout; terminal 

 clasp segment moderately long, swollen at the base and tapering api- 

 cally. Harpes moderately long, swollen basally and tapering to an ir- 

 regularly rounded, sparsely setose apex. 



Wings hyaline, costa reddish brown, the third vein uniting with the 

 thickened costa just before the middle, the whitish discal spot small, 

 the fifth vein joining the posterior margin at the distal third, its branch 

 near the basal third ; halteres yellowish white apically, pale straw bas- 

 ally. 



Coxae dark brown, legs mostly brownish straw ; claws moderately 

 slender, strongly curved, simple, the pulvilli as long as the claws. 



Female. Length .75 mm. Antennae short, dark brown; 12 segments, 

 the third and fourth narrowly fused, the fifth with a length one-fourth 

 greater than its diameter, the terminal segment with a length nearly 

 three times its diameter, narrowly rounded apically and evidently 

 composed of three closely fused segments. Palpi; first segment short, 

 irregular, the second narrowly oval, with a length over twice its diam- 

 eter, the third one-half longer than the second, more slender, slightly 

 swollen distally; terminal segment about two-thirds the length of the 

 second, narrowly oval. 



Mesonotum dull black, the submedian lines sparsely haired. Scu-

A Hermaphrodite of Andrena cressoni Robt. (Hym.). 

 On April 25, 1915, while collecting bees from the blossoms of plum 

 trees at White Heath, Illinois, I obtained a specimen of Andrena cres- 

 soni that presents in itself certain characters of both sexes. The en- 

 tire head including the color of the clypeus and sides of face is that of 

 a male. The head is symmetrical and the antennae are both typically 

 male. The thorax is rather stouter than that of the normal male. The 

 abdomen is typically female and the genitalia including the weak sting 

 is of that sex. The hind legs are identical with those of a nor- 

 mal female, the scopae being well developed. In the great majority 

 of cases hermaphroditism is evidenced longitudinally; here the divi- 

 sion is transverse. J. R. MALLOCH, Urbana, 111.
