my series is 5 to 10 mm. Stethon pectorosus occurred from 

 June 28 until July 7 on dead elm. I took two specimens of 

 Adelothyreus dcjeanii Bonv. running on the trunk of dead 

 Beech. Nematodes atropos and penetrans both occurred, June 

 and July, on dead trees and logs, the former rare and the 

 latter common. Mr. Blanchard of Tyngsboro, Mass., reminds 

 me that in Revised List Cin. Coleop. I had overlooked the 

 fact that Fornax hornii Bonv. was the other sex of calceatus 

 Say, as mentioned in my former list, and the genus Tharops 

 has been superseded by Isorhipis (See Biologia Vol. 3, pt. i.) 

 This makes twenty-eight species of the sub-family occurring 



here. 



Rediscovery of a Lost Species. 



While collecting insects in a Beech woods near this city 

 June 24 to July 8, 1903, I observed a bright green chryso- 

 melid running rapidly over the leaves of " Boneset" (Eupato- 

 riiiDi ageratoidcs.} The beetle was Very shy, taking flight 

 quickly if approached. By rapid strokes of a butterfly net I 

 captured 31 specimens, both males and females. An examina- 

 tion reveals some characters of considerable interest. I feel 

 satisfied that the species is Say's long lost and doubted " Ga- 

 leruca dorsata' (See Horn's Galerucini, Trans. Amer. Ent. 

 Soc. xx, p. 132.) Say gives the " Arkansa above the Virdi- 

 gris," as the locality of his type. The female is } inch long, 

 as given in Say's description, but the male is a little less. The 

 color is bright green, shining. By oblique light it changes to 

 deep blue. There is a pale border around the elytra. Say's 

 description fits the female well. He evidently did not see the 

 male, as he does not mention the remarkable male characters, 

 which are, a large deep fovea with a short groove leading into 

 it, situated near the suture, a short distance from the apex on 

 each elytron, and a curious modification of the anteunal joints 

 5-6 and 7 best shown in the drawing. 



The species seems to be a Diabrotica and not Galeruca, and 

 should stand as Diabrotica (forsafa (Say.)
