Our species of this family have not yet been monograph(Ml, and 

 there exists much confusion among the species of Myz'ine, which ap- 

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

 Eli.s, the admirable work of Messrs. Saussure and Sichel, entitled 

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

 dispensible. 



Family SAPYGID^. 



This small family comprises some pretty species of moderate size, 

 mostly black in color, spotted and banded with yellow, rarely en- 

 tii'ely black. Westwood considered it as a subfamily of the Scoliidse, 

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

 constriction or furrow between the first and second ventral segments, 

 by the subclavate antennae, by the smooth subcylindrical abdomen, 

 and b}' the different neuration of the anterior wings which have four 

 submarginal cells, i. e. the cubital nervure extends to the apical mar- 

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

 from spines and coarse hairs. Sometimes the aculeus is considerably 

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

 habits, the $ entei'ing the burrows of certain Bees and depositing 

 its eg-ops 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 antennae similar in the sexes. 



Ensapyga Cress. 

 Vertex without smooth raised spots; ocelli distinct; pale line on inner ()rl)its not 

 raised ; apex of antennae dissimilar in the sexes, that of 'J, more or less 

 thickened, with the terminal joint much smaller than the jk luilt iinate.

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 descriptions of the new species indicated therein have 

 not yet been published.
