the tropical portions of the earth are as rich, or richer, in these groups (he presumably 
refers to Telephoride) than the cooler parts. ‘The Lycide, Telephoride, Lampyridae, 
and Cleride clearly show a closer relationship between our fauna and _ that 
of Tropical South America than with any they possess with that of America 
north of Mexico—this being rendered even more apparent in such large genera as 
Calopteron amongst the Lycids and Chauliognathus in the Telephorids. More striking, 
however, is the marked peculiarity of the Central and South American genera as 
compared with the faunas of other parts of the globe. The author remarks :—‘ If it 
were true that similar conditions would produce similar forms, how is it that the 
specialized genera of the Neotropical regions are so dissimilar from those of the 
Asthiopian and Indo-Malayan? Of the few genera common to Central America and 
to the Palearctic or Tropical regions of the Old World, there is not one which is not 
of the rank of feebly differentiated forms, or persistent forms of an earlier stage of 
development. The total absence of many widely distributed well marked forms cannot 
be explained by any intrinsic dissimilarity in the conditions, which certainly do not 
differ more than they do in the wide areas over which such genera are dispersed, but 
rather by the isolation from these other areas, contact with which is only effected 
through the northern parts of the globe. One further fact is noted, viz., that, to 
whatever cause it may be due, where a genus is common to Central or South America 
and other distant parts of the World, it is also the case that it is represented by a 
species also identical or nearly related in the two districts. In this case its presence 
must be due to recent transmission, through artificial means, or to the conditions 
having long remained practically similar under which it exists in places so far apart.” 
Thirteen coloured plates are issued in this Volume, 330 species being figured. 
Some of the Clerids received by us since the conclusion of Mr. Gorham’s work have 
been described by Herr 8. Schenkling in German publications, and a certain number 
of Bostrychide have been dealt with or revised by M. P. Lesne. The Chauliognathine, 
Malachiide, and Melyridee, and a portion of the Ptinide, have also been revised by 
Mr. G. C. Champion (Trans. Ent. Soe. Lond. 1913, 1914).

The fourteen families included in the Heteromerous-series are dealt with in two 
volumes: (1) Tenebrionide, Cistelide, Othniide, Nilionide, and Monommide ; 
(2) Lagriide, Melandryide, Pythide, Gtdemeride, Xylophilide, Anthicide, Mordel- 
lide, Rhipidophoride, and Meloide. ‘The general ‘ Introduction’ (published in 1893), 
which includes a Table showing the geographical distribution of the genera repre- 
sented within the limits of Mexico and Central America, is given in part 1. The 
total number of species enumerated is 1776, of which 1295 are treated as new. 
Amongst the Tenebrionidee, the apterous terrestrial forms clearly belong to the
