Our species of this* family have not yet been monographed, and 

 there exists much confusion among the species of Myzine, which ap- 

 pear to be quite variable. In the study of the genera Scolia and 

 Elii, the admirable work of Messrs. Saussure and Sichel, entitled 

 " Catalogus Specierum Generis Scolia" 1864, will be found to be ii.- 

 disjiensible. 



Family SAPYGID^. 



This small family comprises some pretty species of modoiate size, 

 mostly l)hu'k in color, spotted and banded with yellow, rarely en- 

 tirely black. Westwood considered it as a subfatnily of the Scoliidse, 

 but it is readily distinguished from that family by the absence of the 

 constriction or furmw between the first and second ventral segments, 

 by the subclavate antenme, by the smooth subcylindrical abdomen, 

 and by the different neuration of the anterior wings which have four 

 submarginal cells, i.e. the cubital nervure extends to the a])ical mar- 

 gin of the wing ; moreover, the legs are slender, smooth and free 

 froni spines and coarse hairs. Sometimes the aculeus is considerably 

 exserted. The species are probably parasitic, cuckoo-like, in their 

 habits, the 9 entering the burrows of certain Bees and depositing 

 its eggs in the cells of the latter. 



Table of Genera. 



Vertex with smooth raised spots; ocelli small, indistinct; pale line on inner or- 

 bits more or less raised or blistered; apex of antennse similar in the sexes. 



Eusapjga Cress. 

 Vertex without smooth raised spots; ocelli distinct; pale line on inner orbits not 

 raised; apex of antennse dissimilar in the sexes, that of % more or less 

 thickened, with the terminal joint much smaller than the penultimate. 



Sapyga Latr. 



The species belonging to the genera characterized above, have been 

 tabulated in a short paper read before the Entomological Section of 

 the Academy of Natural Sciences of Philadelphia, November, 1880, 

 but detailed descrij)tions of the new species indicated the>*ein have 

 not yet been published.
