PAPILIO VII. 



yellow oil the black ground ; in the cell the yellow spots are repeated and en- 

 larged ; the base of cell is dull or luteous yellow, and sends out four long raya 

 which nearly reach the middle ; secondaries have all the nervures black, those 

 about cell and the basal portion of the costal nervure being heavily edged with 

 black ; the lunules much enlarged and changed into subquadrate spots, occupy- 

 ing fully half the border, the black ground above them being heavily dusted 

 with yellow and blue ; the fulvous of anal spot is changed to oi'ange-yellow, and 

 the two yellow discal spots against cell sometimes have their outer ends yellow- 

 tinted. 



Body black on upper side, elsewhere yellow, but about the thorax fulvous- 

 tinted ; a black stripe from the head reaches the insertion of the wings ; beneath 

 abdomen two black stripes, and one on lower part of either side, from wings to 

 last segment ; legs black ; palpi yellow, or with a fulvous tint ; frontal hairs 

 black, but next the eyes yellow : antennas and club black. 



Female. — Expands 4.25 inch. 



Similar to the male, the yellow paler ; the blue clusters larger and more dis- 

 tinct. 



I described this species as a variety of H'qipocrates in 1876, from a female 

 taken by Mr. Henry Edwards, at the Dalles, Columbia River. Mr. H. K. Morri- 

 son took several examj^les of both sexes in Washington Territory, near Olyinpia, 

 in 1879, and from some of these the figures on the Plate are drawn. In all 

 I have examined, 2 (? 3 ? . I am satisfied they are not Hippocrates, but a dis- 

 tinct species, of same sub-group, and near to ZoKcaon. Felder, Verhand. Zool. 

 Bot., Geschied xiv. pp. 314, 362, 1864, describes Hijjpocrates as much larger 

 than 3Iachaon, the yellow area narrower, the wings narrower and more pro- 

 duced ; the hind wings also shorter on the costa, more produced posteriorly; the 

 tails longer, the anal spot more obscurely colored, and joined abruptly to the 

 blue lunule ; the black border of the hind wings on the under side much broader, 

 the blue spots more distinct, and placed almost in the middle of the black ground, 

 the outer ones accompanied by few yellow atoms, and the cells of both wings 

 lonuer. 



To this may be added that the black marginal border of hind wings on upper 

 side is considerably broader than Machaon, if I may judge by 3 ,? of Hippoc- 

 rates, from Japan, before me. In all these this border is nearly straight-edged 

 on the inner side, and almost touches the cell in two examples, and quite 

 touches it in the other ; and the tails, beside being longer, are not tapering as in 

 Machaon, but are of nearly even width almost to the extremity, where they be- 

 come broader, or sub-spatulate. Oii the under side of primaries the black eel-
