tivelv iniiinportant. It is remarkable, however, that von Hey den, in his descrijifitni, 

 takes the same view of it as I have done. I have not attempted to give the shading 

 of the darker parts of the wing, partly from its obscure nature, partly from a 

 doubt whether they really represent the original markings of the insect; for the 

 basal half of the under surface of the hind wings, where most of the dark mot- 

 tling in Yon Heyden's figure occurs, is usually devoid of any such variegation in 

 the insects of this group; they are almost always of a uniform grayish or brownish 

 hue. Von Heyden's figure does not show the division of the palpal joints.

URBICOLJE - ASTYCI. 

 PAMPIIILITES SCUDDEU. 



This genus belongs to the Astyci and falls in the neighborhood of Pansydia 

 and Carystus, if we take as an illustration of the latter group the Hesperia Lucasii 

 of Fabricius. The former genus has a male with a discal dash, the latter without 

 one. As the fossil species is represented by a single fore wing of what is probably 

 a female, it is impossible to say into which category it would fall. The costal border 

 (PI. Ill, fig. 18) is almost exactly straight throughout; next the base, however, it is 

 arched a little and it slopes slightly downward on the apical fifth to a rather sharply 

 defined apex; the outer margin is gently and almost regularly convex, but with its 

 greatest convexity a little above the middle, and at its upper end is at right angles 

 to the tip of the costal margin; the lower angle is rounded off and the inner mar- 

 gin is slightly sinuous, being hollowed in the middle ; the wing is slightly more than 

 tAvice as long as broad. In all these respects it agrees far better with Pansydia 

 (PI. Ill, fig. 15) than with Carystus (PI. Ill, fig. 13). Indeed, excepting in the 

 greater length of the wing and the lack of any change of direction in the outer 

 border at the tip of the lowest median ncrvule, the form of the wing scarcely dif- 

 fers from that of Pansydia Mesogramnia. 



In neuration it agrees better with Pansydia than with Carystus. Pocy's fig- 

 ure, which for want of better material I have been forced to copy in illustration, is
