" Gall. An irregular, inflated, rounded gall, with the top 

 broadened and somewhat flattened, the edges surrounded with 

 short, blunt tubercles, which are probably the apices of elevated 

 ribs. 



" Gall-fly. Male and female. Length, 2.2 to 3 mm. In the 

 male the two basal antennal joints and legs are red; in the female 

 the whole abdomen is red ; rest of the insect black. Head finely, 

 closely punctate, the vertex almost smooth, thorax, scutellum, 

 and pleura rugose, parapsidal grooves distinct posteriorly, some- 

 what obliterated by the sculpture anteriorly, .the middle lobe with 

 a central longitudinal depression. Antennae 14- jointed, the third 

 joint very long, more than twice as long as the fourth. Wings 

 hyaline, veins brown, the areolet large, cubital cell almost closed ; 

 in the female the basal vein of the closed radial cell and the 

 radius are surrounded with a dusky cloud, which is wanting in 

 the male." 



Galls on rose, probably Rosa Carolina, answering this descrip- 

 tion, were received from Sharon, 27 August, 1915, where they 

 were collected by Mrs. Harriet K. Taylor.

CHALCIDOIDEA. 



MISCOGASTERID^. 



This family is not included in the key to families, but is related 

 to the Perilampidse and Eurytomidse, from which it differs in 

 the pronotum being conical, or conically produced anteriorly, or 

 very short, transverse-linear and very much narrowed medially, 

 rarely as wide as the mesonotum, rarely transverse-quadrate; 

 furthermore, in this family the mesepisternum is triangular, not 

 large. The fore femora are never much swollen, and the hind 

 femora are also normal or only slightly swollen ; the marginal 

 vein in the hind wings usually long ; the costal cell not reaching 

 to the booklets or spinulse and most frequently narrow; radius 

 well developed. This family is superficially like the Pteromalidae, 

 from which it differs especially in its two-spurred hind tibiae. 



Megorismus Walker. 

 Clypeus not transverse, antennae 12-13 jointed; pronotum not 

 distinctly separated from the mesonotum, notauli complete, deli- 

 cately impressed posteriorly, mesonotal lobes flat or at most sub-
