the insect he thus identified, though I have doubts as to the identity of 

 our atcrrimus with that recorded from Europe. Lundbeck is respon- 

 sible for a record of its occurrence in Greenland, while Johannsen re- 

 cords it from Michigan and New Jersey. I have not seen European 

 examples. 



The early stages are undescribed. 



5. Camptocladius flavens, n. sp. 



Male. — Greenish yellow, subopaque. Mesonotum rarely with indi- 

 cations of pale brownish vitt?c. Wings whitish, veins colorless. 



Palpi 4-jointed; apical flagellar joint distinctly, but not greatly, 

 longer than the other flagellar joints combined. Pronotum of moder- 

 ate breadth, without central dorsal excision. Hypopygium as in Fig- 

 ure 15, Plate XXX\"I, and Figure 5, Plate XL. Legs rather stout; 

 fore tarsi without long hairs, basal joint about half as long as fore 

 tibiae (21 : 40) ; mid and hind legs with long hairs. Third vein end- 

 ing beyond beginning of apical curve of wing and very slightly in 

 front of apex of upper branch of cubitus; costa extending distinctly 

 beyond apex of third vein; distance from cross vein to apex of first 

 distinctly less than that from apex of first to apex of third (19: 25) ; 

 cubitus forking very slightly beyond cross vein, posterior branch dis- 

 tinctly bisinuate (PI. XXXIX, Fig. 16). 



Female. — Agrees in color with the male except that the apical an- 

 tennal joint is brown. 



Palpi as in Figure 12, Plate XXXVIII ; antennal flagellum has the 

 joints much longer than their diameter, the basal two closely fused, 

 and the sensory organs hairlike (PI. XXXVIII, Fig. 14). Apex of 

 abdomen as in Figure 16, Plate XXXVIII. 



Length, 2-3 mm. 



Type locality, Havana, 111., April 29, 1914, on Illinois River (C. A. 

 Hart and J. R. Malloch). Paratypes : St. Joseph, 111., May 17, 1914, 

 on bank of Salt Fork (C. A. Hart and J. R. Malloch), and'South Ha- 

 ven. Mich., July 14, 1914, on shore of Lake Michigan (Hart). 



This species differs in color from C. fuinidus Johannsen, and from 

 C. graminicola Lundbeck, a Greenland species, in having the wings 

 bare. 



6. Camptocladius flavibasis, n. sp. 



Female. — Brownish l^lack, slightly shining. Head fuscous, face, 

 antennae, and palpi yellowish brown. Pronotum, anterior lateral an- 

 gles of mesonotum, and upper portion of pleurae yellowish. Abdomen 

 brownish black, opaque, yellowish at base and on venter. Legs brown-
