below more coarsely so and the metanotum rugose reticulate. Abdomen 

 without any indications of sutures, elongate oval, rather more slender than 

 usual, its thickest portion scarcely beyond the middle; its surface longitudi- 

 nally aciculate with occasional reticulations. Legs, or at least the posterior 

 femora dark in color. Wings rather strongly infuscated. 



Type.— No. 2341, M. C. Z., Florissant, Col. (No. 9150, S. H. 

 Seudder Coll.). 



The type is not very well preserved, but is evidently specifically 

 distinct from the other specimens of Chelonus in the collection. 



Chelonus solldus, sp. nov. (Fig. 81.) 



Length 4.5 mm. Dark colored or black, the antennae including the scape 

 light brown. Head finely rugulose, but not at all aciculated. Antennae not 



preserved at the tip, but their 

 basal portion is apparently 

 normal. Mesonotum rather 

 finely rugose or coriaceous, the 

 pleurae very coarsely rugose, 

 especially below. Metanotum 

 not visible as the legs are ex- 

 tended directly above it. Abdo- 

 men obovate, the thickest part 

 near the tip; no traces of any 

 transverse sutures. Its surface 

 finely rugose reticulate as is usual 

 in the genus. Wings hyaline, the stigma and veins dark. Venation not 

 well enough indicated to describe. 



One specimen, No. A126, collected by Mr. S. A. Rohwer at Station 

 14. Type in the collection of the Amer. Mus. Nat. Hist.

Chelonus solidus sp. nov. 



Type. 



Chelonus depressus, sp. nov. 



Female? Length 4-4.5 mm. Color black or very dark, the antennae, 

 and the legs, except the posterior femora and tibiae rather light brown. An- 

 tennae two-thirds as long as the body, about 25-30-jointed, setaceous, the 

 small joints toward the apex quadrate-moniliform, and the larger basal joints 

 from two to three times as long as thick; scape globose. Body rather strongly 

 sculptured. lace confluently punctate, the front above, and the vertex also 

 to some extent, transversely rugose. Pleurae slightly rugulose above, smooth 

 below except along the sutures. Metanotum rugose, with reticulations pos- 

 teriorly which form a series of more or less distinct small areas. Abdomen
