with typical Uay'molita^ and seemingly ha\dng similar phytophagous 

 habits, are excluded from the genus because of the fact that in each 

 species a few poorly defined and obscurely umbilicate punctures 

 occur on the mesonotum. In the opinion of the writer these species 

 are more closelj' related to Harmolita than to any other genus of 

 the Eurytomidae and such differences as exist are not believed suffi- 

 cient to justify the erection of a new genus for their reception. 

 The whole family Eurytomidae is much in need of a thorough revi- 

 sion, and until such a revision is published it is deemed best to place 

 the following described species (as well as the other mentioned above 

 which is described elsewhere-) in the genus Harmolita even though 

 perhaps slightly extralimital in some characters. 



The genus as recognized by the writer is characterized by having 

 in the female an elongate, conical or subfusiform, subpetiolate abdo- 

 men which is weakly or not at all compressed laterally and in which 

 the segments are more or less subequal, the fourth segment never 

 greatly enlarged as in Eurytoma. The head as seen from above is 

 transverse, convexly rounded in front, the occiput slightly concave, 

 and iimnargined; viewed from in front the head is usually somewhat 

 broader than high, truncate below, and not strongly convex above, 

 the cheeks rounded ; antennae inserted at or above the middle of face, 

 placed close together at base ; the scrobes moderately deep and narrow 

 with the lateral margins rounded; scape not long, more or less com- 

 pressed; flagellum weakly clavate; pedicel longer than broad; two 

 small ring joints; funicle usually five-jointed and the club 3-jointed, 

 but in some cases the funicle appears to be 6-jointed and the club 

 2-jointed; pronotum large, the dorsal portion however, broader than 

 long, frequently somewhat broader than the mesoscutum, its an- 

 terior dorsal margin rounded ; mesoscutum strongly trilobed ; scutel- 

 lum large, longer than broad and rounded at apex; propodeum not 

 or scarcely longer than the scutellum, not sharply declivous, usually 

 rugosely sculptured with a more or less distinct median longitudinal 

 depression; legs normal; wings usually ample (absent in some cases) 

 the marginal vein distinctly longer than the postmarginal which is 

 variable; stigmal subequal to or distinctl}^ shorter than the post- 

 marginal. Sculpture of head and dorsum of thorax either reticulate 

 and shining, rugulose punctate without umbilicate punctures, or 

 rugulose with a few more or less indefinite umbilicate punctures. 



Tlie male abdomen is subcylindrical, rarely longer than the thorax 

 with a distinct moderately thick petiole. The antennae are long, 

 filiform, usually slender, the flagellar joints elongate and fusiform, 

 rarely more or less distinctly excised at apex, and always with long 

 hairs Avhich are sometimes arranged in whorls.
