MEXICAN HYMENOrTEUA. 29 



ba.sal two-thirds of second segment with dense, fine oblique strije : apex 

 of first segment smooth above. Length 3 J lines. 



% . — Difi'ers from the $ as follows : the posterior orbits are broadl}- 

 interrupted behind ocelli ; the black mark on pleura is larger, the lower 

 half is transversely striated, with two black spots arranged longitudi- 

 nally; base of posterior coxae broadly black, posterior tarsi yellow, 

 basal half of all the tibise, the four anterior tai'si and base of posterior 

 pair are also black; abdomen longer and narrower, the pale apical 

 margins of second and following segments are narrower, and the apex 

 of first and almost the whole of second segment covered with fine ob- 

 lique strige. Length 4 lines. 



Tv/o ( 'S 9 ) specimens. The dilated portion of first abdominal seg- 

 ment is entirely black.

? Ichneumon breviventris, Cresson, Proc. Eiit. Soe. Phil. iv. p. 12. 

 Three $ , three % , specimens. (Sumichrast Coll. No. 4.) Seems 

 to diff"er from the unique Cuban specimen only by the more dense pune- 

 tatiou of the mesothorax, by the sparsely punctured scutellum, by the 

 first abdominal segment being rugose and not aciculate, and by the 

 base of the fourth segment above being sometimes black. The 9 is 

 (iolored like the % , with the antennte stouter and convolute, that of 

 the % is slender and gradually attenuated to the ti})s, which are very 

 slender. This is not a true Joppa. 



2. Joppa inclyta, n. p. 



9 . — Very closely allied to picta, Guer., but difi'ers by the longer 

 antcnnfe, by the metathorax having a short subbasal, transverse, cen- 

 tral, yellow line, instead of two transverse spots, the apical spots being 

 longitudinal and large, by the first four segments of the abdoni'-n
