being pale, piceous and vittate forms ; from Vancouver I have two 

 examples, one entirely luteous yellow, the other piceous black. An 

 example from New Mexico differs greatly from any of the varieties 

 mentioned by Dr. Horn. The surface of the thorax is entirely smooth, 

 even, polished and shining ; convex, sparsely and finely punctured ; the 

 elytra are also smooth and shining with a fine but sparse punctuation ; 

 the antennae are ferruginous, and the legs variegated with pale and fuscous. 

 General colour of the insect chocolate-brown. Length, .29 inch. Set 

 beside the atra of the same size with semi-costate elytra, it is difficult to 

 believe them to belong to the same species. 



Zeugophora consafiguinea, Cr. — This is a form of varians in which 

 the thorax is entirely rufous. In collecting varians, perhaps one example 

 in twenty will be so coloured. I do not know of its occurrence except 

 with varians. 



Bruchus obsoletus, Say, B. rufitnanus, Bohm., B. lentis, Bohm. — The 

 American history of these unwelcome foreigners has been presented in a 

 very masterly and satisfactory manner by Mr. J. A. Lintner (Seventh Rep. 

 on the Injurious and other Insects of the State of N. Y., 1891). B. 

 rufijiianus, it appears, is not known to be naturalized, though bred twice, 

 or oftener from peapods or beans brought from Europe, and is the B. 

 granarius of Mr. Fletcher's Report (1888). B. lentis occurred at 

 Buffalo, N. Y., in a provision store where imported lentils were kept on 

 sale, and was distributed to cabinets under the name of B. rufimajiiis, 

 but did not acclimate. B. obso/etus, Say, is discussed in twenty-five 

 pages. It was first discovered at Providence, R. I., in i860. The beans 

 supplied to the soldiers of the armies during the war of the Rebellion 

 were largely infested with it. It spread slowly westward to and beyond 

 the Mississippi and northward but is not known to have entered Canada 

 so far, Mr. Lintner. B. obsoletus was prevalent here several years ago, 

 but has entirely disappeared, none having been observed by cultivators in 

 its old haunts for about five years. No means of extermination, nor 

 to prevent its spread, were employed. It is certainly extinct here. That 

 it may likewise become extinct from climatic causes, at least in the 

 Northern States, is far from improbable. According to Mr. A. Fauvel 

 this Bruchus is of Neotropical origin and native in Central and South 

 America. This clearly accounts for its non-acclimatization in Canada, 

 and holds out a hope of its eventual extinction here. Through favouring 

 conditions it was spread very widely, but except in a few localities it is
