8 THE CANADIAN ENTOMOLOGIST. 



during the summer when using a beating net. During May the curious 

 larvae of certain Lampyridae were often seen in damp woods, crawling on 

 the trunks of trees, such as cedar, or affixed by the tail to the bark, under- 

 going their metamorphoses in a similar manner to the larvge of the Coc- 

 cinellidse. Some reared at home emerged as Phottnus atigulaius. The 

 larvffi, and to a less degree, the pupse, emitted a strong greenish glow from 

 two of the posterior segments ; the imago being, of course, one of our 

 common " fire flies." Some of the larvae were thickly covered beneath 

 with small ticks, of a bright vermilion color, which had their pointed heads 

 plunged between the armored segments of the larvae. They were not 

 easily dislodged, but walked rapidly when free. By these little parasites 

 the larvae were so weakened as to perish before completing their transfor- 

 mations. The warm weather of raid-May brought forth increased hosts 

 of insects, and the sultry air, especially in the neighborhood of lumber 

 yards, swarmed with Scolytidae, etc. Toward the end of the month I 

 took a trip, with three friends, to the AVakefield Cave, about twenty miles 

 north of the city ; and in my spare moments collected a number of insects 

 in that vicinity. Cicindelidae especially abounded oa the sandy hill-side 

 roads, and I captured three species which are rare, or not found about 

 here, viz., C. i2-guttata, C. longilabris and C. Umbalis. On my way back 

 I took a specimen of C. sex-guttata having only two spots (the anterior 

 one on each elytron). Although called Six-spotted Tiger Beetles, very 

 many have eight spots, and si^ecimens with ten spots are freque:itly taken. 

 In a beech grove at Chelsea, Ithyceriis airailionides was very abundant ; 

 several could be seen on nearly every tree ; many pairs were copulating. 

 Where do the larvae live ? On the 3 1 st of May several specimens of C. 

 Harrisii were taken on pine saplings, and H. pales and its long-snouted 

 relatives were in full force. On June 4th, Saperda vestita, Oberea aina- 

 biiii, B. nasicus, C. nenuphar, A. quadrigibbus, and many other weevils, 

 elaters, etc., were noted. At an excursion of the Ottawa Field Natural- 

 ists' Club to Montebello (45 miles down the river), on 26th June, I 

 captured 129 species of Coleoptcra, a considerable percentage of which 

 were new to me. Carabidre were particularly abundant under drift-wood 

 and dead leaves on the damp, shady shore, and 35 species were taken. 

 Chrysomelidae, Elateridae and Curculionidae were next in number with 

 15, 13 and 13 species respectively. After midsummer my opportunities 

 for collecting were few, and my notes correspondingly scanty. I will 

 merely mention the capture at Aylmer and Hull, on Oct. 2nd, of Aletia
