Several galls and one adult in good state of preservation are in the collection. 

 The gall is the product of Holcaspis globulus (Fitch) and the type of oneratus is a

THE MALLOPHAGA OF THE WORLD: SYSTEMATIC SUMMARY. 



BY VERNON L. KELLOGCx, STANFORD UNIVERSITY, CALIF. 



After many tedious hours I have made an end of compiling a catalogue, with 

 references to original descriptions, and with host and geographic records, of the 

 Mallophaga of the world, for }>ublication in Wytsman's Genera Insectorum. This 

 is a highly needed work — not the list of Mallophaga, but the Genera Insectorum — 

 and I suppose no sacrifice of time and happiness on the part of an entomolooist is to 

 be reckoned too great, if he can help further this larger enterprise. But doino- the 

 Mallophaga has approached, from my point of view, somewhere near the limit of 

 this sacrifice. 



Twelve hundred and fifty-seven species of these little parasites of birds and 

 mammals have been described: 52 from mammal hosts and 1205 from birds. About 

 one fourth of these are recorded from North American hosts, and of these approxi- 

 mately 300 species two thirds have been described as new, the other 100 being con- 

 sidered to be identical with species originally described from European, Asiatic or 

 African hosts. 



The order Mallophaga comprise twenty-seven genera, grouped into four families, 

 constituting two sub-orders. Each sub-order includes a family found on bird hosts 

 and one found on mammal hosts. However, a few species in the bird-infesting 

 families are being found on mammals, especially on kangaroos and wallabies in 

 Australia. Of course, in addition, a number of normally bird-infesting species have 

 been found as stragglers on bird-catching mammals. The division of species among
