CALYOZA.— AMISEGA. 457 



Head, pro- and mesothorax, with the scutellum, closely and finely punctured, 

 shining. Metanotum very shining, finely transversely striated, and with three longi- 

 tudinal keels in the middle ; the central keel straight, the lateral ones curved inwardly ; 

 there are two transverse keels across them near the centre ; the apex is almost perpen- 

 dicular, keeled at the top, and with a keel down the middle. Abdomen shining, the 

 base hollowed in the middle. The base of the antennae and the apical six joints are 

 obscure testaceous ; the other joints fuscous-black. The coxse and the greater part of 

 the femora are black ; the four hinder tibise are in great part fuscous-black. The front 

 legs are stout, the femora especially; the middle legs are more slender than the 

 posterior. The anterior spurs are long, curved, and slender. 



Fam. CHRYSIDIDJE. 



Comparatively few species of this elegant family are known from the Neotropical 

 region. The North-American Chrysididse have been monographed by Aaron (Trans. 

 Am. Ent. Soc. xii. pp. 209-248) ; this author divides the family into four subfamilies, 

 all of which are represented in our fauna. 



Subfam. CLEPTINjE. 



Cleptes is the only genus included hitherto in this subfamily ; but the characters 

 given for the group by Aaron will have to be altered if Amisega is to be included in it. 



AMISEGA. 



Antennae 13-jointed, inserted immediately over the mouth. Eyes large, parallel, reaching near to the base of 

 the mandibles, and almost to the back of the head. Prothorax quadrate, broader than long, slightly 

 narrowed in front and shorter than the mesothorax. Parapsidal furrows complete. Postscutellum simple, 

 not projecting. Metathorax and median segment with a gradual slope to the apex, and without teeth or 

 projections of any kind; a margined furrow runs down the centre and on either side of the metanotum. 

 Abdomen with four segments ; the basal two segments large and subequal, the apical segment small. 

 Marginal cellule elongated, complete. 



This genus agrees with Cleptes in having the face convex, without an antennal groove, 

 and in the form of the abdomen ; but it differs in having the prothorax broader than 

 long and not much narrowed in front, as well as being shorter than the mesothorax, and 

 in having the metathorax rounded and not angled laterally. 



I include in Amisega a single species from the State of Panama.
