194 HYMENOPTEEA. 



Hab. Panama, Volcan de Chiriqui 2500 to 6000 feet l (Champion). 



Occiput, the upper part of the back, and the front of the head to the base of the 

 antennae, except the orbits of the eyes in front, black, smooth, shining, impunctate. 

 Mesonotum shining, bearing a few scattered punctures. Scutellum with prominent longi- 

 tudinal striations. Metanotum hollow in the middle, the hollow transversely striated ; 

 the top smooth, shining, slightly punctured, as are also the sides. Petiole smooth, 

 shining; postpetiole longitudinally striated. Gastrocceli transverse, shallow, smooth 

 shining; the second, third, and basal three fourths of fourth segment longitudinally 

 striated ; the apex of the fourth shining, bearing a few punctures ; the other segments 

 impunctate, shining, as are also the coxae; the third and the following abdominal 

 segments are black entirely, except that there is usually a dark fulvous mark on either 

 side of the third above. Tarsi black, except the anterior pair at the base ; femora and 

 the four anterior tibiae more or less lined with black behind ; posterior tibiae white, 

 black at the extreme base and broadly so at the apex. Labrum in the centre, the apex 

 of the mandibles, and the spurs, black ; face and petiole yellowish ; the thorax may be 

 testaceous or dark fulvous. The body is closely covered with fuscous pubescence, 

 almost black on the abdomen. The cloud in the apex of the wing commences a little 

 beyond the stigma. The male does not differ in coloration from the female. 



- 3. Joppa elegantula. 



Joppa elegantula, Cresson, Trans. Am. Ent. Soc. ii. p. 32 ( $ ) 1 . 

 Hab. Mexico, Orizaba, Cordova x (Sumichrast). 



A specimen from Sabo, Vera Paz (Champion), is perhaps referable to this species, 

 it differing from the type merely in having the hind coxae entirely black, and the tibiae 

 black at the base, and in having a small yellow spot on either side of the third abdo- 

 minal segment. It differs from J. varipes in having only a small triangular black mark 

 on the vertex covering the ocelli, in the hind femora being entirely black, except at the 

 base, and in the hind coxae being black; the metanotum behind is not so strongly 

 striated, and the second segment is black at the base. 



4. Joppa variolosa. 



Joppa variolosa, F. Smith, Descr. of New Species of Hymen, p. 232 \ 

 Hab. Costa Kica, Cache * (Rogers). 



From the typical /. elegantula this species differs in having the hind coxae and 

 trochanters black, except at the extreme apices ; the four anterior femora black, except 

 at the base and apex (elegantula has the " tips of them behind " only) ; all the tibiae 

 black at the base, the front pair lined also with black behind ; and the metanotum 

 can scarcely be called " longitudinally rugulose." It is more slender than the above- 

 described variety from Sabo, with which it agrees in the amount and arrangement of
