136 THE CANADIAN ENTOMOLOGIST. 



I do not wish to be construed as wantonly criticising a paper that dis- 

 tinctly adds to our knowledge, but the facts as stated are so at variance 

 with my personal observations that I must ask my friends to look again. 

 The best way would be by isolating single nymphs and carefully following 

 each through all instars. The plate of this life-history is more satisfactory 

 than the other, although both are excellent. It depicts the ova, three 

 nymphal instars, and the adult, and from these figures one is struck with 

 the great similarity of the species to our native forms of Alydus. On the 

 whole, as an addition to our knowledge of life-histories in a much- 

 neglected group, this paper is of value. A more profound study of 

 nymphal variations in structure and appendages would have greatly 

 enhanced its importance, but knowing as I do, the difficulties incident 

 on such work it is only bare justice to commend highly the good begin- 

 ning made. 



The Catalogue of the Hemiptera of Fiji is conceived and carried 

 out in the spirit of accuracy so characteristic of its author's work, and 

 reflects his well-known views on phylogeny and synonymy, the arrange- 

 ment of the Heteropterous families being that he has adopted for his 

 forthcoming catalogue. This paper is based on the collections made 

 by Koebele and Muir when searching for parasites to control the sugar- 

 cane leaf-hopper, and includes an account of some Hemiptera from 

 Charles H. Knowles, Superintendent of the Department of Agriculture of 

 Fiji. The previous total of 40 Hemiptera known from the Islands is in- 

 creased to 205, but he says, it is evident that the endemic forms are 

 scarcely collected. " Fiji was associated, by Wallace, with the Pacific 

 Islands, in a ' Polynesian sub-region,' but its Hemipterous fauna seems 

 decidedly continental, and to be included in the ' Austro-Malayan Sub- 

 region ' of the Australian Region." 



Eleven genera and thirty-four species are described as new. The 

 catalogue is enriched by notes on food-plants, habits, occurrence, de- 

 scription of nymphs, and other valuable details. The plate figures the 

 widely-distributed Orthcea ( = Pamera) vincta, Say, brachypterous adult, 

 nymph, and tegmen of macropterous form ; Brachylybas variegafus from 

 above and from side, together with the odoriferous orifice, much enlarged ; 

 Ontiscus vitiensis ; the tingids Mesocyfiselas dicysta and Holophygdon 

 me/anesica, from above and from side : and the hemelytra of Pioiariodes 

 medusa. Taken as a whole, this is a most important addition to our 

 knowledge of the Hemipterous fauna of the Pacific 1-lands.
