Description
Excerpt from Chalcidids Injurious to Forest-Tree Seeds<br/><br/>This insect is considered by its original describer as probably-a parasite of 'a gall ?y. Inhabiting the fruit of mountain ash (sorbus scandics), but Crosby has proven the species as entirely phytophagous in habit, and has reared it from seeds of Sorbus aucuparia. Crosby describes the larva as white, smaller than the larva of Syntomaspis drupar-um, from which it may be distinguished by the mandibles having four teeth on their inner margin and by the absence of brown tubercules on the face. The oviposition habit and the egg of this species are unknown, but it may be presumed that they are similar to those of the foregoing species.
