t<) some extent the form us originally described, were due to ima- 

 turity. Subsequently specimens were obtained at Lancaster (Los 

 Angeles Co.), California, by Mr. Koebele, both from cecidomyid and 

 dipterousgal Is on Arteini'ila californica. 



30. A. ten iii forme n. sp. — Very narrow, black, sparsely pubescent. Beak 

 about as long: as tlie head and prothorax, not slender, rather strongly arcuate, 

 scarcely dilated, finely sculptured nearly to the tip; punctuation sparse, fine, a 

 little stronger at the side. Antennee short, first joint equal to the next two. sec- 

 ond reaching the eye. outer joints transverse. Front punctate, not sulcate; eyes 

 moderate. Prothorax about as long as wide, widest a little before the base ; sides 

 parallel for a short distance at the apex, thence feebly arcuate to the base, which 

 is a little wider than the apex ; surface rather sparsely, but strongly, not coarsely 

 punctate; a short impressed line at the base. Elytra parallel, about twice as long 

 as wide ; humeri small ; stria not deeply impressed : intervals somewhat convex. 

 Punctures beneath deep but not close. Length 1.5 mm.; .06 inch. (PI. IIL 

 figs. 5 and 5a). 



% . Sutural angles rounded ; intermediate femora stouter ; first joint of middle 

 tarsi spined. 



9. Sutural angles not rounded; femora and tarsi unmodified. 



Ifrtft.— Florida. 



Collections of Mr. Schwarz and National Museum. This species 

 would perhaps more appropriately be placed with those showing 

 like sexual characters, and is only retained here because of the 

 simple claws. 



31. A. aoropliiliiiii n. sp. — Black; pubescence very short, fine and sparse. 

 Beak ( % ) rathei- stout, scarcely as long as the head and protliorax, nearly cylin- 

 drical, feebly dilated at the middle, finely sculptured nearly to the tip ; punctua- 

 tion close and rather coarse at the sides, finer and less close above ; apex shining ; 

 ( 9 ) ii little longer dilatation post-median, tip somewhat expanded, otherwise in 

 the male. Antennte inserted at the middle ( % ), or a little more basal ( 9 ), first 

 joint but little longer than the second, shorter than the next two, fourth reaching 

 the eye. Front punctate and canaliculose at the middle; eyes not very promi- 

 nent. Prothorax transverse; sides divergent to the middle, then parallel to the 

 base; apical constriction small; surface dull, densely punctate, with a linear 

 basal fovea. Elytra about one-half longer than wide, widest near the middle: 

 humeri moderate; post-humeral sinuation small ; intervals not wide, nearly flat. 

 Beneath deeply, densely punctate. Legs not stout; claws obtusely swollen at 

 base. Length 2.1-2.3 mm. ; .08 .09 inch. (PI. III. fig. 12). 



% . Sutural angles rounded : all the tibiae feebly mucronate. 

 9 . Sutural angles not rounded ; tibife unarmed. 



Hnb. — Colorado (Garland). 



Collections of Dr. Horn, Mr. Schwarz and ^Tr. Howditch. This 

 species closely reseml)les crlbncolle, and would certainly be placed 

 next to it were it not for the simple claws. Aside from this, aero 

 j)hiluiii differs by its longer beak, with the anteniue inserted at a
