massasoit is exceedingly abundant in the swamps near Westville, 

 N. J., from the 4th to the loth of July, and you can get them as 

 fast as you can use net and bottle. I think it quite a pretty spe- 

 cies when fresh; it has such pretty velvety-brown wings. Mr. H. 

 G. Willard, of Grinnell, Iowa, informs me that Amblyscirtes 

 samoset flies there in the woods about June 9th, but is anything 

 but common. Mrs. Slosson has also taken a few specimens of 

 this rare species at Franconia, N. H. I will now skip from the 

 skippers and give a couple of new localities which are interesting. 

 Mr. H. G. Willard has sent me Chrys. helloides from Iowa. Mr. 

 Edwards' catalogue gives Montana to Arizona; Oregon, Califor- 

 nia. M. C. H. T. Townsend has sent me Synchlce crocale from 

 Las Cruces, N. Mex.; types, I think, came from western Ariz. 

 The New Mexico specimens lack the internal row of white spots 



on the secondaries.

An Exorista parasitic on Lagoa opercularis. 



By C. H. TYLER TOWNSEND, Las Cruces, N. Mex. 



Dr. Alfredo Duges, of Guanajuato, Mexico, has kindly given 

 me an Exorista labeled " from the cocoon of Lagoa opercularis." 

 It agrees with none of the twenty-six new species described by 

 Mr. van der Wulp in the " Biologia Centrali- Americana," and a 

 description of it is presented below. It belongs near E. flavicans 

 v. d. W. among the species with ciliate hind tibiae. 



Exorista lagoae nov. sp. $. Black, cinereous with a more or less brassy 

 reflection. Eyes dark brown, thickly pubescent; front, sides of face, 

 cheeks and posterior orbital margins pale brassy; front at vertex narrower 

 than the eyes, much wider at base of antennas, rather prominent; frontal 

 vitta black, less than one-third the frontal width, wider anteriorly, pronged 

 posteriorly; frontal bristles descending to base of third antennal joint, 

 those before base of antennae decussate, the sides of front with fine bristly 

 hairs outside the frontal row and on the ocellar area; no orbital bristles; 

 face receding, facial depression wide, silvery; facial ridges bare, only three 

 or four very small bristles above the vibrissfce, which latter are decussate 

 and inserted only slightly above the oral margin; sides of face narrmv 

 above, very narrow below base; cheeks narrow, invaded below by the 

 cinereous hairy occipital area, witli bristles on lower border ; antennae 

 nearly as long as face, black; second joint short, third joint more than 

 four times as long as the second; arista long, slender, scarcely thickened 

 on basal third, indistinctly jointed at extreme base, black; proboscis short, 

 fleshy, brownish, especially the large labella, which are furnished with
