different genitalia of the male, the ventral aspect of the praeputium 

 being very short, as in figure 3a, and the apices of cochlearium being 

 simple. 



Type. — Zdlagium dypeatum Rohwer. 



Only two species of this genus are known from North America. 

 These have the metanotum practically impunctate. 



Abdominal segments three to six, reddish yellow; middle fovea very poorly defined; 



hypopygidium obtusely pointed cinctuhim . 



Abdomen entirely black; middle fovea well defined; hypopygidiiim subtruncate and 



slightly eniarginate apically dypeatum. 



ZALAGIUM CINCTULUM 

 (Norton). 



Tenthredo atroviolacea var. 

 cindula Norton, Trans. 

 Amer. Ent. Soc, vol. 2, 

 1869, p. 240, female; Nor- 

 ton Catalogue, p. 172. 



Macrophya abhotii Ejrby, 

 List Hym. British Muse- 

 um, vol. 1, 1882, p. 269, 

 pi. 10, fig. 14, male and 

 female. 



Norton's type is per- 

 haps lost. Every spec- 

 imen in the collection 

 has the posterior coxae 

 entirely black and the 

 species extends from 

 Massachusetts to Geor- 

 gia. It is therefore 

 probable that Norton 

 omitted to say the black 

 spot was wanting. It 

 is certain that the spe- 

 cies here treated as cinc- 

 tulum is the same as 

 abhotii.

ZALAGIUM CLYPEATUM, new species. 



Except for the characters mentioned in the table and the rather 

 shorter antennae this species is the same as cvmctulum. 



Male. — Length 10 mm. Pedicellum about twice as broad as long; 

 antenna! fm-rows present only just above the antennae; median 

 frontal area sUghtly raised; area between ocelli and orbits depressed;
