Tijpe-locility. — -Mount Union, Pennsylvania. 



fype.—C^t. No. 20274, U.S.N.M. 



One female (Hopkins No. 7557) reared June 17, 1908, by R. W. 

 Van Horn, from a red maple stump infested by Cerambycidae and 

 Eucnemidae and also containing the clerid, Cymatodera undulata. 



Named for Mr. S. A. Rohwer. 



This species presents a rather peculiar combination of characters. 

 The head is of the type shown in obereae Viereck and its closest allies, 

 as is also the thorax except for its slenderness and the fact that the 

 propodeum extends beyond the middle of the coxae, both of which, 

 together with the very slender strongly compressed abdomen ally it 

 with the more typical species, but the uninclosed first sternite and 

 broad stigma with distally originating radius refer it without doubt to 

 Zale'pto'pygus. 



CREMASTUS (ZALEPTOPYGUS) ANOMALLS, new species. 



Female. — ^Length 7 mm., antennae 3.5 mm., ovipositor 2.3 mm. 

 In the strong compression of the abdomen and lack of scutcllar carinae 

 this species is allied to rohweri Cushman, but is otherwise abundantly 

 distinct, as follows: Eyes parallel below, distinctly shorter than width 

 of face; malar space distinctly shorter than basal width of mandible; 

 clypeus about two-thirds as long as interfoveal line, weakly convex, 

 strongly rounded at apex; interfoveal line much longer than foveo- 

 ocular line; face evenly, moderately punctate throughout, except 

 narrowly in orbits; anterior orbits not swollen; lateral ocelU much 

 less than half as wide as postocellar line, the latter slightly longer than 

 ocell-ocular line. Thorax stout, the propodeum declivous behind and 

 reaching but a short distance over coxae; thorax throughout much 

 less strongly punctate; scutullum unusually deeply convex, almost 

 appearing swollen; propodeal carinae rather weak, areola and petiolar 

 area weakly separated, the former short, pentagonal much shorter 

 than latter; sculpture of all areas weak, apical areas obscurely rugu- 

 lose, others punctate; radius arising very shortly beyond middle of 

 stigma; second discoidal cell nearly half as wide at base as at apex; 

 second recurrent interstitial; nervellus perpendicular; hind basitarsus 

 relatively as long compared with tibia but shorter than other joints
