 N. M. One specimen, July 18 (T. D. A. Cockerell). In sculpture 

 and size this comes nearest to optima which, however, differs in 

 having the length of pronotUm almost equal to the length of the 

 head, and in the uniformly different sculpture. 



Tetraohysis ceerulans Fabr. 



Two % % , one July 27 (T. D. A. Cockerel!). 



Tetraelirysis nortoui Aar. 



One £ , July 24, Heracleum lanatum (T. D. A. Cockerell). 



TIPHIID.E. 



Tiphia odontogaster n. sp. — Third, fourth and fifth ventral abdomi- 

 nal segments with a short tooth near the lateral margin. 



% Length 8 mm. — Clypeus closely punctured, front with shallow punctures 

 almost confluent, a triangular polished space directed down from the anterior 

 ocellus. Punctures behind ocelli, smaller and more imperfect than those on front. 

 Third joint of antennae distinctly shorter than the fourth, the rest subequal. 

 Prothorax margined. Punctures on pronotum like those of front, but more 

 separated, the posterior margin, smooth, polished. Dorsulum still more sparsely 

 punctured, scutellum with two smooth areas of small size and large punctures. 

 Postscutellum more finely and uniformly punctured. Propleune on upper half 

 almost smooth, on lower half from finely to coarsely striate. Mesoplenrse with 

 a strong ridge, behind which the surface is regularly punctured with rather large 

 shallow punctures. Disc of metathorax with a longitudinal enclosure, about one- 

 half again as wide where it joins the postscutellum, which will be called the 

 base, length of the enclosure about twice width at apex. The area strongly de- 

 fined, a distinct longitudinal raised line extending along its whole length in the 

 middle. The transverse ridge distinct, joining the lateral longitudinal ridges, 

 making a houuded petiolarea, which is roughened, finer and more opaque op the 

 lower half than above. Metapleura with strife curved forward from the lateral 

 carina to near the middle of the metapleune, the surface beyond roughened 

 opaque. Wings clear, nervures very dark brown, stigma black. Basal nervine 

 bent and thickened near the intersection of the cubital nervure. First abdomi- 

 nal segment strongly convex, at base with a node on each side. Polished above, 

 the punctures rather sparse, the punctuation on the sides much closer. Second 

 abdominal segment with well separated punctures, the rest of the segments have 

 the punctuation closer and closer. The entire insect covered more or less with 

 fine silvery pubescence. 



Black entirely.
