ment reduced, irregular. Palpi: first segment subquadrate, the second 



with a length three times its diameter, the third longer and stouter 

 than the second, the fourth one-half longer than the third, irregular, 

 somewhat capitate. 



Mesonotum light yellowish hrown. Scutellum, postscutellum and 

 abdomen mostly light yellowish. Halteres yellowish white. Coxae 

 pale yellowish. Legs mostly light straw; claws moderately stout, strong- 

 ly curved, unidentate, the pulvilli shorter than the claws. 



Genitalia, yellowish brown ; basal clasp segment rather long, stout : 

 terminal clasp segment moderately stout, recurved apically ; dorsal 

 plate divided, the lobes moderately broad, broadly rounded and sparsely 

 setose apically ; ventral plate shorter, the lobes narrow, obliquely trun- 

 cate apically. 



Type: Cecid. 1660. 



Dasyneura lupini n. sp. 



The galls from which this species was reared were collected 

 by Mr. L. H. Weld at Buena Vista Park, San Francisco, 

 California, August 25, 1915. They occurred on a perennial 

 species of Lupin us which was shrubby at the base, much 

 branched, 2 to 4 ft. high and perhaps Lupinus propinquus. 

 The galls were kept outdoors by Mr. Weld and a lot forwarded 

 to the writer early the following May from which specimens 

 of both sexes were obtained May 10. The male of this species 

 runs in our key to D. incliloti Felt, from which it may be 

 separated by differences in the genitalia, especially in the shape 

 of the lobes of the dorsal plate. The female of this Lupine 

 species is remarkable for the very long lobes of the ovipositor. 



Gall. Irregularly fusiform, presumably stem gall, light green when 

 fresh, fleshy, quite firm, polythalamous, the interior fibrous and inhabit- 

 ed by a number of larvae; length, 1.5 to 2.5 cm.; diameter, i to 1.5 cm. 



Cocoon. Oval, length about 2 mm., rather firm in texture and light 

 yellowish. 



$. Length, 1.75 mm. Antennae about as long as the body, thickly 

 haired, reddish brown; 16 or 17 segments, the fifth with a stem three- 

 fourths the length of the cylindric basal enlargement, which latter has 

 a length about one-half greater than its diameter and a moderately 

 thick whorl of long, stout setae; terminal segment slightly produced. 

 narrowly oval, with a length about twice its diameter. Palpi : first 

 segment irregularly quadrate, the second a little longer, more slender, 

 the third one-half longer than the second, more slender, the fourth 

 one-half longer and more slender than the third.
