47. Ruyncnota Hetrrorrera. Vol. II.: by G. C. Champion: Tingitids-Corixide. 
Mr. Champion here deals with nineteen families of Rhynchota Heteroptera (making 
twenty-four in all), twelve belonging to the Gymnocerata and seven to the Crypto- 
cerata. The number of species enumerated is 592, nearly half of which are 
described as new. Fifteen additions to Vol. I., described or recorded by various 
authors in other works, between 1893 and 1901, are noted on p. 384, the total 
number of Heteroptera enumerated in the two Volumes being 1715. The Tingitide, 
Aradide, Reduviide, and Anthocoride are abundantly represented in Central America, 
the respective numbers for each being 78 (66 new), 78 (40 new), 204 (78 new), 
and 54 (32 new). As with the five families belonging to Vol. I., no comparison is 
made with the fauna of the adjacent regions southward for want of sufficient data. 
Most of the genera belonging to the aquatic Cryptocerata are, in common with other 
water-insects, more or less widely distributed. The twenty-two plates, six of which 
are coloured, include figures of 513 species, a complete list of which is given in the 
Introduction, pp. xi-xvi. The Index for the two volumes is included in Vol. IL, 
pp. 385-416. 
48. Ruyycnota Homoptera. Vol. 1.: by W. L. Distant and W. W. Fowler: Cicadide— 
Delphacide. 
Mr. Distant’s first contribution to this Volume, on the Cicadide and Fulgoride, 
pp. 1-41, was published in 1881-1887, the Supplement to the same, pp. 42, 43, in 
1900, and the Appendix, pp. 140-146, in 1905, his work having been interrupted 
during long absences from England. The rest of the volume, dealing with three 
additional species of Dictyopharine, the Flatide, Derbide, Cixiidw, Achilide, Isside, 
and Delphacide, by the Rev. W. W. Fowler, pp. 44-139, 146, 147, appeared in 
1900-1905. Apart from the Cicadide and Fulgoride, very little appears to be known 
about the South American members of the above mentioned families, and nearly all the 
Central American representatives are described as new by Mr. Fowler. Altogether 323 
species are enumerated, 208 of which are treated as new, with twenty-five new genera. 
The thirteen coloured plates include figures of 267 species, a complete list of which 
is given in the Introduction, pp. vii-ix. Four species of Cicadide are also figured 
in the text, on pp. 140-143. A few Central American Cicadide have since been 
described by Mr. Distant in other publications. 
49, Ruyncnota Homoprera. Vol. II. Part 1, by W. W. Fowler: Membracide- 
Gyponide. Part 2, by T. D. A. Cockerell: Aleurodide and Coccide. 
Part 1 of this Volume contains the enumeration of four more families of Homoptera 
—the Membracide, Cercopide, Tettigoniide, and Gyponide, 659 species in all 
(exclusive of the 29 noticed in the Supplement, some of which are doubtful), 385 of 
of these being described as new, with 42 new genera. Pages 1-316 were published
