The Ooleoptera and Hymenoptera, however, seem to warrant a few remarks, as a supple- 

 ment to my former very imperfect paper, and I have therefore prepared tables showing 

 the number of genera and species in the families represented in these orders. 



COLEOPTERA. 



About seventy-five per cent, of the genera occur in Canada, and while probably 

 not more than half a dozen species are common to the two countries, there is on the 

 whole a striking similarity of form and ornamentation, with a sprinkling of conspicuously 

 exotic looking individuals. One such species is found in the Cicindelidas (C. chinensis 

 v&rl) which wa? abundant on the Usui Toge, about one hundred miles northward from 

 Yokohama, and still more so at Chofu, near the straits of Shimenoseki, several hundred 

 miles southward. This beetle is very gaily coloured and appears very brilliant when 

 flying or running in the sunlight. 



In Carabidfe the striking genus Damaster is represented by two species (probably 

 D. pandarus, and D blaptoides), from Chofu and Yokohama. There is ? very fine Carabus, 

 and among species closely resembling American forms may be mentioned two of Scarites, 

 a Panageus, a Dromius, and four or five of Chl;enius. Water beetles were not searched 

 for, but among the few obtained are three fine species of Cybister and a Hydrophilus 

 more robust in form than our //. triam/ularis. Staphylinidse were not numerous, although 

 the few species represented apparently furnish one which occurs in Canada, viz., O.vyteles 

 fiiscipenne, which flew into our chamber at Nikko one damp evening in great numbers, 

 and a species more like 0. rugosus, of which one specimen only was taken. Although the 

 Histeridse are not represented in my coUectini, I captured on Enoshima (island famous 

 for glass sponges, shells and marine curiosities) a species much larger than any of the 

 American forms known to me, but the specimen was afterwards lost. 



One of the coasting steamers upon which we spent a day or two, swarmed with 

 Silvamts surinameTisi>:, and afforded also another cosmopolitan species, N^ecrobia ru/iaoUis. 

 A few specimens of Derodontus beaten from foliage at Yokohama, are perhaps identical 

 with D. trisignata, which occurs in British Columbia. A curious Trogositid of a bronzy 

 colour, with two yellow tubercles on each elytron, might from its size and sculpture be 

 readily mistaken at first sight for a Buprestid near Chrysobothris. The splendid buprestid 

 Chrysocht'oa fulgidissima, brilliant green with purple stripes on thorax and elytra, is not 

 uncommon in the forest regions of Nikko and Hakone, and is said to infest several trees, 

 including the Keaki [Zdkoiva Keaki) which furnishes very valuable timber. There is 

 also a smaller Chrysochroa, more subdued in colour, but still a very handsome in.sect, 

 which appears to be less abundant. From the mountainous province of Shinshiu (famous 

 for its silk-worms) I have two examples of a fine Chalcophora, much like C. forth in 

 sculpture, but larger .
