thus the Oxyuri would be connected with Cleptes, as Chrysis is with 

 the Chalcidites, and form a commodious transition to the Formi- 

 car ice. 



Among the Chrysidid^ M. Klug first distinguished those which are 

 characterized by the diiference of the number of abdominal segments 

 in the two sexes. The disappearance of the submarginal and dis- 

 coidal cells in the fore wing here indicates an approach to the second 

 chief division of the Chrysididce, yet it appears more suitable to 

 place them not at the end but at the head of the first division, and 

 thus entirely at the head of the Chrysididce. Only one genus belong- 

 ing to that section Pai-fiopes, w^hich is distinguished by the porrect 

 linear mouth, is yet known. To this a new genus is now added. An- 

 thracias, a female, with two abdominal segments and with a short 

 mouth more like that of Chrysis. The Chrysididce with an equal num- 

 ber of abdominal segments in both sexes are divided froni the form 

 of the body into oblong and round, the first with distinct lower mar- 

 ginal and discoidal cells in the fore wing and simple claws, the last 

 ■with obsolete cells and cleft claws. In the divisions themselves the 

 generic characters should be taken from the formation of the mouth 

 alone, according to whether it, or especially the ligula as in Par^ 

 nopes, be linear and porrect or not, and at the apex emarginate or 

 rounded, or lastly short and almost conical. In the first division 

 with simple claws, next to Parnopes, or rather Anthracias, a new ge- 

 nus Leptoglossa should follow, not dissimilar to Eiichroeus, with a 

 porrect ligula and emarginate at the apex ; then Pyrochloris, also 

 with a porrect ligula and rounded at the apex ; after which. Euchroeus, 

 subdivided according to whether the apex of the abdomen (as is usu- 

 ally the case here) is serrated, or indented, or quite unarmed; and then 

 the genus Stilbum, w^hich hardly differs sufliciently from Euchroeus. 

 The conclusion of the first division would be formed by the genus 

 Chrysis, which is the most abundant in species, and which might be 

 much subdivided from the structure of the mandibles, completeness 

 of the marginal cells in the superior wings, and the direction of the 

 nerves forming them, projection of the scutellum, and the armature 

 of the apex of the abdomen, but is nevertheless well characterized 

 by the short nearly conical ligula. In the section of Chrysidida with 

 divided claws, the difference between the genera Elampus and Hedy- 

 chrum consists either, as in Chrysis, in the short or conical ligula, or 

 as in Euchroeus and Stilbum, only in the more projecting ligula 

 emarginate at the apex and without regard to the projection of the 

 scutellum. — From the Bericht der Berliner Akademie, 8^c.,for 1839.
