THE CANADIAN ENTOMOLOGIST. 67 



A considerable portion of the volume is devoted to morphological 

 discussions, illustrated by three well-executed plates. These abound in 

 comparative notes, and are of great value in throwing light on the 

 phylogeny of the groups, since the palaeontological record is nearly blank. 

 Chapters are given to the sternal structure, the coxal articulations, the 

 abdomen, the elytral epipleurse, the hind wings, the elytral markings (this 

 last with over a hundred text figures, showing the development and 

 modifications of the colour pattern), and the vestiture. From the study 

 of the markings the conclusions are drawn that identity of pattern is by 

 no means always indicative of close relationship, although related species 

 have usually similar markings, and that longitudinal marks in the Cicin- 

 delinDs are secondary rather than primary developments. 



The chapter relating to geographical distribution and zoogeography 

 is full of interesting details and conclusions. The number of genera and 

 species increases as the equator is approached — this may be seen readily 

 by reference to the illustrative plate. Besides a very considerable portion 

 of the colder boreal and austral lands, a great part of the Pacific island 

 area is without Cicindelinse. The genus Cicindela has the widest range, 

 Megacephala (including Tetracha) coming next. Some of the species of 

 both of the above genera have extremely wide range, others show remark- 

 able cases of discontinuous distribution. Only two genera are Palaarctic, 

 four Nearctic. The Neogaeic (South American) region is very rich in 

 generic types, eighteen being found there, of which two extend to the West 

 Indies. The Ethiopian region is believed to be the originial home of the 

 ancestral Cicindelinse of both phyla, and contains representatives of most 

 of the modern groups. The Oriental region yields ten genera, and the 

 same number is known to inhabit the Notogseic region, i.e.^ the xA.ustro- 

 Papuan-Polynesian district. 



The phylogeny of the tribes of Cicindelinae and of the principal 

 types of the genus Cicindela is worked out and illustrated by two plates. 

 From a study of relationships, the author reaches the conclusion that the 

 Cicindelinae form a branch of the family Carabidae, coordinate with the 

 Carabinse as a whole. Between the most primititive genuine Cicindelinae 

 and the corresponding Carabinse on the one hand and their common 

 Cicindelid-Carabid ancestor, a number of coordinate intermediate forms 

 have been given off, two of which may be identified with the recent phyla 

 of Cicindelinte. 



That portion of the •' Special Part " which has come from the printer 

 is concerned with the Ctenostomini and the CoUyrini. The former tribe
