 type male, collected at West Rock, New Haven, Conn., August

Tiphia relativa n. sp. 



In structure and sculpture approximately like the preceding species. 

 The antennae entirely black and the tarsi more blackish than brownish. 

 The inclosure is rather coarsely rugulose with no trace of a bisecting 

 line. In the paratype the inclosure is more or less completely bisected. 

 The typical form has the wings colorless, excepting the nervures and the 

 stigma. Four of the paratypes belong to a variety with brownish wings. 



Type locality. North Haven, August 3, 1905 (B. H. W.). 

 The var. from E. Hartford, August 2, and Scotland. 



Odynerus (Ancistrocerus) waldonii n. sp. 



Closely related to birenimaculatus, but with ornaments white 

 as in albophaleratus. 



? 13 mm. In most respects like birenimaculatus. The metathorax, 

 however, different in that the ridges bordering the posterior aspect are 

 not very transient and lacking two sharp teeth at the summit. The 

 maculation differs as has already been pointed out. In addition to the 

 difference in color, there is a difference in extent and pattern. For 

 example, the scape, postscutellum and metathorax are immaculate, 

 excepting four small dots on the postscutellum. The second dorsal 

 abdominal segment is immaculate, except the apical margin. The 

 clypeus has two brown dots, one a short distance on either side of the 

 center or near the center. There is a median longitudinal brown line on 

 the posterior fourth of the clypeus, extending to the superior margin of 

 the clypeus. On the anterior third of the clypeus, extending to the 

 anterior margin, there is a brown funnel-shaped mark, terminating in a 

 brown line. There are no two lateral oblique spots on the first abdo- 

 minal segment. The coxae are immaculate, as are the femora, except a 

 yellow spot at apex of the anterior femora, and more or less brownish 

 at anterior aspect of the anterior femora, and a narrow brownish margin 

 at apex of middle and posterior femora. The tibiae on the anterior 

 aspect and outer aspect mostly yellow, brown posteriorily and at apex. 

 Tarsi entirely brown. 



Type locality. New Haven, Conn. 



One female taken May 15, 1903, by B. H. Waldon. 



Anoplius humilis Cress. 



Previously known only in the 9 sex. The $ differs from 

 the 9. in the usual way and in having nearly all of the basal 

 half of the posterior aspect of the posterior tibiae and the dorsal 

 apical abdominal segments whitish. 



One $ , New Haven, June 9, 1905 (B. H. Waldon).
