abdomen rather indistinctly subfasciate, apical margins of segments 

 coloured like the rest of the surface ; sixth segment with a very small 

 notch ; seventh bidentate, the teeth short and broad ; genitalia nearly as 

 in O. ifiurbana, \v\\\ch. belongs to a. different group; third ventral seg- 

 ment formed and fringed nearly as in O. pseudamala. The abdomen has 

 only piliferous punctures. Easily known from O. Ramaleyi by the longer, 

 yellowish-tinted hair on the apical half of the abdomen. The female 

 doubtless has a light scopa. 



SOME HULST TYPES OF GEOMETRID.E AT WASHINGTON. 



BY RICHARD F, PEARSALL, BROOKLYN, N.Y. 



A recent visit to the U. S. Nat. Museum, at Washington, for the 

 purpose of studying types of this family, contained in its collections, 

 disclosed some facts which" it seems advisable to record. The following 

 were deposited by Dr. Hulst : 



Tephrodysiis nivei/asc'a. — Type No. 3920 is the specimen recorded 

 by him as coming from Oregon. It bears the label "Kcjebele, Oregon," 

 only, and is not conspecific with the one in the Hulst collection at New 

 Brunswick, which, in a former paper, I have already stated, finds its place 

 under the genus Nasusina Pears., and will now constitute the type of the 

 species. Among material submitted to me some time ago, and returned 

 to the Museum at this lime, I had described as new a single specimen, 

 under the name, Eiip. segregata, n. sp., which seems to be the same as 

 the Oregon type, and 1 have therefore transferred the name to it, Dr. 

 Dyar having generously permitted me to retain as a co type the second 

 specimen of segregata, a description of which will be found in a forth- 

 coming paper. 



Tephrodysiis phivibaria. — Type No. 4701 is a fine female examj^le 

 oi Eup. miseridata Grote, labelled Washington, D. C., July 5th. 



Tephrodystis plejwscripta. —Ty\)t 4702 is the true type recorded 

 from Yellowstone Park, Wyoming. A specimen from the same locality is 

 in the Hulst collection at the Brooklyn Institute Museum. The latter repre- 

 sents the usual appearance of specimens, the type being an unusually 

 clear, distinctly-marked example. 



Tephrodystis fltbilis. — Type No. 4920, recorded from Alaska, is a 

 silky-gtay si)ccies, with the same general appearance as biviitata Hulst, 



September, 1910
