cubitus Stands fof the second recurrent ner^re. Petiole of abdo- 

 nren a little less than twice as long, as broad at ■>?«. -»™^ *"" "°^ 

 slroDdy, on the disk the punctures are d.stmct, rather deep, large 

 Id "parated. The sides of the petiole are rather moderate^ 

 .ugulo^; second segn^ent shining, punctured, *e pnnctures clo^r 

 together on the sides than on the disk and not as lar-ge as those on 

 the disk of the first segment or petiole, the rest of the dorsal sg- 

 ments finely punctured on the apical half, second ventral segment 

 more coarsely and closely punctured than the second dorsal -gmen. 

 In the middle of the base of the exposed portion of the third dorsal 

 segment is visible an area with a subtle surface m outline lAe a 

 U The second dorsal segment has a lateral hue appre^^ed-lAe 

 pubescence near the margin silvery, in some lights of a dirty ap- 

 pearance; on the second ventral segment is a similar line, but less 

 Ln one-half the length of the one on the dorsal segment. The 

 entire insect is almost uniformly covered ivith a moderate amount 

 of long, fine, while, erect pubescence; that on the dorsulum and 

 margins of the segments is shorter and lies rather close. 



Brownish testaceous; legs pale testaceous, antenna; duU, duty 

 testaceous, tips of the mandibles dark brown.

One ^, taken at light, July 31 (T. D. A. Cockerell). In the 

 .hape of the mesosternal process this species comes close to the type 

 of the genus, but it is quite different in many respects. 

 Odontophotopsis succineus n. sp. 



Process of mesosternum a sharp tooth, in outhne a a acute angle. 

 The tooth is short, ^s in melUcausus ^nd brevicornis, but sharper 

 Lenc^th c?, 7.5 mm. Clypeus slightly concave, shmmg. Head 

 polished, punctures small and sparse. Instead of a furrow runnmg 

 from the anterior ocellus to between the insertion of the antenna 

 there is a dent a short distance below the anterior ocellus, and from 

 this a rather indistinct impressed line appears to extend to the 

 margin of the clypeus. Hardly any space between the base o 

 mandibles and the lower margin of eyes. Postenor ocelh about 

 twice as far apart as they are distant from the antenor ocellus the 

 space between the posterior pair distinctly less than U.ai between hem 

 and nearest margin of the eyes. First joint of flagellum a trifle 

 shorter than the second. Mandibles not so strong, gently curved,
