tibialis, co-type Akidoproctus kelloggi. In the collection of J. C. 

 Crawford, Jr., are the types of Ninmis truncaius var. magnocephalus 

 and Akidoproctus kelloggi. In the collection of Professor V. L. 

 Kellogg are co-types of Akidoproctus kelloggi, Nitzschia pulicaris var. 

 tibialis and Nirmus angustifrons. In my own collection are types 

 of Docophonis cephalosiis, Nirmus iufrequens, Physostomum picturatus, 

 co-types of Nirmus truitcatus var. maguocephalus, Nirmus trimarginis, 

 Niruuis biocellatus var. nigropictus, Nirmus angustifrons, Akidoproctus 

 kelloggi, Nitzschia pulicaris var. tibialis.

/,;v;/a/,'. — Body, length 1. 55 mm., width .68 mm , deep smoky brown through- 

 out with darker markings, body short, head large, wider than the abdomen, and 

 ta[)eiing sharply to the narrow, truncate clypeus ; abdomen nearly obscured by the 

 deep chestnut lateral blotches. 



Head, length .57 mm., width .72 mm.; wider than the abdomen, tapering 

 sharply from the rounded temples to the comparatively narrow clypeus; front trun- 

 cate, slightly concave ; tip of clypeus colorless, with two short marginal and two 

 dorsal hairs at the lateral angles; one short hair near the clypeal suture and two 

 behind it; trabecule large, slightly curving and bluntly pointed; antennje* short 

 and stout, first two joints longest, remainder short and subequal ; eyes prominent, ob- 

 scured with brownish, with a short hair ; a notch at the posterior angle of the eye ; 

 temples broad and rounded with two rather short pustulated hairs; occipital margin 

 deeply concave ; antennal bands heavy to the suture, where they are broken, then 

 continuing to the clear portion of clypeus as narrow marginal bands ; the posterior 

 portions bend inward at the trabecule and meet over the mandibles ; a short ocular 

 band from base of antenna; to eye ; temples narrowly margined with blackish-brown, 

 shading inward; occipital bands slightly darker than ground color, running to base 

 of the mandibles, where a curving branch is sent off to join the ocular blotch just 

 before the eye ; a transverse clear band just behind the heavy curving antennal bands. 



Prothorax short, almost hexagonal, with a short hair at the posterior angles ; 

 heavy blackish-brown lateral bands ; median portion slightly clearer than ground 

 color of head. Metathorax about as long as prothorax ; sides slightly concave, 

 broadly diverging ; posterior angles with two rather short hairs, posterior margm 

 angulated on the abdomen, with a row of about nine pustulated hairs on each side ;

Abdomen short, "nearly as wide as long, widest at third and fourth segments, 

 thence tapering sharply to the tip ; posterior angles protruding, with one hair in 

 segments i, 2, 4, and 9, the remainder with two; segments I-7, with large deep 

 smoky-brown lateral bands, completely covering the first segment and separated 

 medially on the remainder by a narrow clear space; the posterior margins of the 

 lateral bands with from six to nine short hairs arising from large clear pustules, eighth 

 segment with a median lighter portion ; ninlh segment very small and rounded. 



*On account of the haste in the preparation of drawings the antennae were 

 omitted.
