Entomological Society of Ontario; Insect pests -- Periodicals; Insects -- Ontario Periodicals. 81 tion of the many genera and species comprised in the family Ulateridce, the remainder of this paper will be devoted to a few brief remarks on some of the more interesting for- eign and native ones. Westwood states that the Elaters ai-e less rich in species than the Buprestians, but that they are more generally distributed. About four hundred and fifty North American species are given by Le Conte in his classification, of which, perhaps, one-fourth are found in Canada. During the past summer I collected in the immediate vicinity of Ottawa fifty species, while of Buprestians I only obtained about half that number. There are perhaps no click-beetles that in form, size or markings are striking when com- pared with many other families of beetles ; they vary but slightly in shape, are of moderate size, and of dull hues generally. One genus, however, [Pyrophorus, containing 30 or more species) is indeed worthy of notice from the power of light-emitting possessed by its members. If sombre by day they are the brightest of all insects when darkness shrouds the world. I have before me a specimen of P. noctilucus, the celebrated " fire- fly " of the West Indies and Central America, called by the Spaniards cucujo. Figure 51 represents this insect both at rest and on the wing. It is nearly an inch and a-half long, (the elytra being exactly an inch from base to tips,) and has a tawiiy grey appear- ance, caused by a covering of short yellowish hairs on a black Fig. 51. Its most important features are two smooth, convex yellow spots, or tubercles, on the thorax—one on either side—from which at night, when the beetle is alive, streams a strong greenish light, far surpassing that of our own " fire-flies," or, correctly speaking, " ; When the beetles are on the wing another patch be
