108 ENTOMOLOGICAL NEWS. [April, 



licaon Cr. , satcllitia, anchcmolus, achemon, labrnscu", nearly all 

 in series and of both sexes, and have had access to figures and 

 descriptions of the others. As an excuse, therefore, for what 

 our editor graphically calls " a head-long plunge into the sea 

 of synonymy," I add hereto a brief comparison with the 

 twenty American species (?) given by Kifby. 



Hiibner's genus Dupo, known as the vitis group, is best 

 known by vitis and liimci ; Jicspcridiitm is an allied form from 

 Jamaica ; hornbeckiana of Harris (by Clemens considered a 

 synonym of vitis), and strcnua of Menetries are both described 

 by Boisduval in full, and both have their fore wings marked on 

 the I'ifis type. Boisduval says of strcnua that it connects :v7/\ 

 and typhon ; and Butler says of both, "allied to linnci."' 

 Tvplion (Klug.), as described by Clemens and by Boisduval, 

 suggests the rosy and brown P. achcmon, to which Clemens 

 says it is allied. Of this latter, P. achcmon, there is no need 

 to speak. We might eliminate also Argeus labrusca-, phorbas 

 and cappronnieri as of an entirely different type, too distinct to 

 need any comparison. 



This brings us to tins, pandorus-satellilia-eacus group ; in this 

 group the large, heavy dark-colored giants anchcmolns and 

 licaon ( Cr. nee. Hub.) may be dismissed without comparison, 

 their size and their browns and violets and pinks making them 

 very distinct. 



Posticatns, of Grote ( licaon of Hubner, nee. Cramer) is about 

 the size of clisa, but has the primaries narrower, is brownish 

 buff instead of green, has the inner margin of fore wings at 

 base of the anal angle of hind wings, rosy. Mr. Butler also 

 calls attention to the distinct rose color of secondaries. 



jlfirijicatits, of Grote, to quote, " is allied to post '/< ':a tits, linnet 

 and strcnua, from all differing by the white linear bands on the 

 forewings, and their apical white line, and by the distinctly 

 Tvhite-banded abdomen and tcgulic : while nearest posticatus in 

 appearance of hind wings, it is most dissimilar in markings of 

 primaries, which are more like those of linnci in the evenness 

 of the ground color. ' ' 



Satcllitia is altogether larger, heavier and is grey or brown- 

 grey ; with the blue-green at base of secondaries like <-/is<t, but
