segment, and most of under side of abdomen, all covered with ap- 

 pressed silvery white hair; labrum large and broad; labial palpi very 

 long, third joint short and stout, fourth long and cylindrical; tongue 

 very long, extending about 2 mm. beyond labial palpi; maxillary palpi 

 rudimentary, apparently i -jointed; clypeus dull, granular, with a me- 

 dian keel, failing below : facial quadrangle much longer than broad ; 

 antennae long, brownish-black, third joint about half as long as fourth; 

 mesothorax densely rugoso-punctate; scutellum bilobed, axillar teeth 

 large; legs with white hair; spurs pale ochreous; small joints of tarsi 

 pale ferruginous; tegulae large, black, punctured; wings basally hyaline, 

 more than apical half fuliginous; b. n. going far basad of t. m. ; three 

 submarginal cells, first r. n. joining second near end; abdomen finely 

 and densely punctate, without bands or spots. 



Hab. — Ega, Brazil. (British Museum, from the Farren 

 White collection). On account of the locality, and the remark- 

 able "mimicry" of a wasp, it is appropriate to dedicate this 

 species to Bates ; who, indeed, very possibly collected the speci- 

 mens. In Friese's key to Rathymus, in which he includes 

 Odyneropsis, this falls next to the much larger 0. apicalis 

 DiJcke, which occurs in Mexico. 



The Genus Parnassius in America (Lep.). 

 By Henry Skinner. 



(Plate XH) 



Four species have thus far been described from North 

 America. As in the Etiropean species, a number of names 

 have been proposed for the variations of these very plastic 

 butterflies. To consider the various forms in a rational man- 

 ner it is necessary to fix the types of some of the earlier 

 names, as some confusion has been caused by authors not 

 knowing what certain names actually represented. We need 

 more knowledge as to the distribution of these insects and 

 also date of capture and altitude of the localities where the 

 specimens are taken. Lepidopterists are not agreed as to the 

 retention of names based on one sex or on size of individuals, 

 this variation in size being usually due to difference in the 

 altitude where the specimens are taken. 



Parnassius clodius was described by Menetries in 1855 and 

 the locality given is California. It is well figured by W. H. 

 Edwards in his Butterflies of North America. Two forms of
