abdominal segments, with apex of ovipositor, piceous brown. The char- 

 acteristic feature of the species is, however, the two light colored ellipti- 

 cal markings upon the disc of the pronotum, as shown in the figure. 

 $ 4 m. m. and $ 3.85 m. m. in length. 

 Habitat. Atlantic States, from Maryland southward. 



MvRMECOPHiLA Oregonensis, n. sp. 



Elongate oval, body somewhat contracted at its junction with the pro- 

 notum, which latter is slightly narrowed at its posterior edge, making its 

 sides appear bulging. It is a more slender species than the preceding, 

 the female of this insect being very similar to the male of that species. 

 Pronotum small, with the sides rounded, posterior edge very slightly 

 arcuate ; meso-, meta-notum and first abdominal segments equal. Cerci 

 or anal stylets comparatively slender, 1.2 m. m. in length. Ovipositor 1.5 

 m. m. in length, medium stout, with the external sheaths slightly longest 

 and pointed, with the points directed outward ; internal ones acuminate. 

 Color piceous brown above, with the under side and base of segments 

 lighter. Antennae concolorous. Disc of pronotum also light colored, but 

 without the two elliptical spots, which are present in M. Perga?idei. 



Female 3.90 m. m. in length, male unknown. 



One mature female and a pupa of this last species were collected at 

 Portland, Oregon, in the summer of 1882, by Mr. Samuel Henshaw, of 

 Boston, Mass. The types are deposited in the Museum of Comp. Anat., 

 Cambridge, Mass. 



OBITUARY NOTICE. 



Mr. Anson Allen died at his home in Orono, Feb. 8, 1884, in the 55th 

 year of his age. He was, without doubt, one of the best collectors, and 

 one of the most careful, accurate and acute observers of insects, their 

 habits and transformations, that we had among us. For a number of 

 years past he spent nearly all the time he could spare from his business in 

 collecting, breeding and exchanging Lepidoptera, and many collections, 

 both in this country and Europe, have been enriched by additions from 

 his exquisite preparations. 



Mr. Allen would never save an insect unless it was absolutely perfect, 

 except such as were very rare. For several years he bred from the eggs,
