214 ENTOMOLOGICAL NEWS. [June, '04 



reticulated ; entire thorax more or less sparingly griseo-pubescent. Wings 

 hyaline, nervures brown ; arrangement of nerves as shown in the figure 

 in fore wing ; the hind wing acute at apex and without a separate anal 

 lobe, anal furrow well marked ; costal and subcostal nervures distinct 

 but closely parallel, forming, especially toward the point where they 

 finally coalesce, just before the hooks of the wing, a distinct though very 

 narrow costal cell, which may be turned over so as to be indistinguish- 

 able from a side view ; the only other nervure, arising beyond the base 

 of the subcosta, bifurcating shortly beyond its origin and extending each 

 fork to the margin, is shown in the figure The tarsi and more or less of 

 the tibiae of the front and middle legs are yellow, the rest black ; pos- 

 terior and middle tibite with two apical spurs ; tarsi five-jointed ; claws 

 with three distinct pectinations beneath. Petiole two-thirds the length 

 of the thorax ; abdomen highly compressed laterally ; the second joint 

 very large, longer than the petiole, remaining joints short, all of them 

 together less than the second joint ; abdomen smooth and highly polished, 

 the apical margin of each joint finely punctured ; ovipositor short, 

 straight, or curved slightly dorsad, and exserted from a distinctly ventral 

 position, pointing dorsad. The ventral and dorsal segments of the abdo- 

 men appear of approximately equal size from a lateral view. Length 9 mm. 



The writer took one female, July i, 1903, at Cobb's Creek, 

 Delaware Co., Pa. It is now in his own collection. 



New Forms of Exotic Papilionidae. 



BY GEORGR A. EHRMAN, Pittsburg, Pa. 



While rearranging my collection of Papilionidae, which con- 

 sists of nearly three thousand specimens from all parts of the 

 world, I find a few representatives that are new to science, 

 and which will be, I am glad to say, of much interest to the 

 student who finds as much beauty in the exotics as some of 

 our entomologists do in our native species. 



Ornithoptera ritsemae Snell., n. var. tantalus. 



Male. An extreme form of O. ritseiiuz ; the upper side of the apical 

 parts of the forewings is much more suffused with yellowish rays than is 

 found in the typical form of this sex of this species. The hind wings have 

 in the submedian space in each cell (the cell between the costal and sub- 

 costal nervures being excepted) a large, elongated, black-suffused spot, 

 and the crimson collar is absent ; these three points of difference make 

 this form very conspicuous. 



This interesting form was collected by Herr John Watersttadt 

 in the German possessions of North Borneo, and through whose
