2 Mr. G. C. Champion on 



so many of which are unique in collections. If the specimen 

 is a male, there is little risk of adding to the synonymy 

 in describing new species from a single example,* the 

 characters to be found in the legs or antennae being 

 often particularly well marked in this sex, sometimes, 

 indeed, of an extraordinary or unexpected nature. No 

 new genera or subgenera are added in the present paper, 

 and dichotomous tables of species are of little or no 

 value unless both sexes are known. Xylophilus doubt- 

 less requires splitting up, but to do it on the characters 

 used by Casey a very large number of " genera " would 

 be re quired, f The Xylophilidae are constantly confused 

 in collections with the much more abundant and more 

 widely distributed Anthicidae, which they may perhaps 

 be said to mimic ; they are, however, always recognisable 

 by their tarsal structure J (the tarsi having each a minute, 

 short, nodiform, penultimate joint preceded by a very 

 much longer, interiorly produced, lobed joint), the fusion 

 of the first and second ventral segments of the abdomen, 

 and the broad apical joint of the labial palpi. 



The new species described are from the following 

 regions : India (including Burma), 31, 4 of them also 

 occurring in Siam, about a dozen others having been 

 previously recorded from the same region ; Siam, 8, in- 

 cluding three found in Tenasserim and one in Ceylon ; 

 Perak, 3 ; Sumatra, 1 ; Selangor, 1 ; Larat, 1 ; China, 5 ; 

 Australia. 4 ; New Zealand, 1 ; S. Africa, 3 ; South 

 America (including Trinidad), 11; Lesser Antilles, 2. 



Mr. Andrewes has kindly lent me the co-types of two 

 Indian species of Xylophilus described long ago by Fair- 

 maire ; and Mr. Bryant the types of two remarkable 

 forms from Trinidad and two from Ceylon, all four recently 

 named by Pic ; figures of these latter are appended to the 



* Out of 17 species captured by Mr. Bryant during his recent 

 expedition to Borneo and Penang, 12 occurred singly. 



f This author, in 1895, placed the 37 recognised N. -American 

 species under 13 genera, but all his new generic names (including 

 Axylophilus, which is doubtless valid) have been sunk as subgenera 

 in Pic's Catalogue (1910). 



X Misunderstood by the artist employed by Mulsant, whose figures 

 of the tarsi of X. jn/gmaeus, de Geer (cf. Colligeres, pi. 1, figs. 1, 2), 

 appear to have been taken from an Anthicid ! Pic's illustrations, 

 too, in Wytsman's " Genera Insectorum " are all incorrect in this 

 respect, including those copied (wrongly) from the " Biologia." 

 Lewis's figure, too, of X. distortus, Champ., is inaccurate.
