very abundant, and the surface to a great extent is covered with several spe- 

 cies of our most common Bijpnum. 



This season I watched faithfully for the appearance of the imago, niakiog 

 occasional visits to the spot during the month of June. It was first observed 

 on the 3rd of July, and between this time and the 20th I made five or six 

 excursions, capturing during the period over 200 specimens. I seldom met 

 with them on the wing, but generally resting on the alders or forus. They 

 were not difiScult to capture, appearing quite tame, and when aroused would 

 fly but a few yards and alight ; even if one escaped from the net it would fly 

 but a short distance, and could be easily recaptured. On dull d:iys they 

 were quite sluggish, sleeping exposed on the upper surface of leaves, and 

 readily taken without the aid of the net. 



It is not improbable that they are double brooded, the Jarvce produced 

 from the eggs of the second brood not appearing until the following spring. 

 I conjecture this from the circumstance of having two years ago seen a female 

 late in August or early in September. 



MISCELLANEOUS NOTES. 



Cai'TURE of Tremex Columba. — One of the objects which the promoters 

 of the (Janadlan Ealomologist had in view, in the establishment of that peri- 

 odical, was, I apprehend, to convey information respecting the appearance of 

 various insects, whether of common or of rare occurrence, within the limits 

 of our Province. Under this impression, I send you a notice of the capture 

 of some specimens of the Tremex Colwmha in our village, a few days ago 

 Last March, an oak, measuring nearly three feet in diameter at the butt, was 

 felled and chopped into cordwood lengths. One of the pieces, a portion of 

 the main stem, was split up the other day, and placed close to a stove for 

 immediate use. On being thus subjected to the influence of heat, several 

 indivicuals of the insect, in the '!ma<jo state, crept out, from various perfora- 

 tions, in a semi-torpid condition, that is to say, they appeared barely able to 

 crawl about,- and made no attempt to use their wings or even to hasten their 

 pedal movements for the purpose of escaping capture. On further search 

 larvœ were also discovered in the wood. I regret to add that all the speci- 

 mens I found were females. Their length, exclusive of the ovipositor, was 

 If in. This is the first occasion of my discovering these insects in this 

 locality. — ViN'CENT Clementi, North Douro, Ont. 



Luminous Larv^. — With reference to our account of a Luminous Larva 

 in No. 1, Mr. AV. Couper, of Ottawa, Ont., writes as follows : — " I frequently 

 found larvge of Lampyridoe, in the daytime under moss and bark of decayed 

 trees, but never noticed them produce light, as you describe. I do not recol-
