INSECTS OF SAMOA. 



TJiree specimens were taken from a Nutmeg tree. They show a close 

 affinity to the Tropical American H. filum, Keitt. Like the latter, the present 



is a small pubescent species of narrow shape, with 

 small eyes. The eyes of H. samoensis, however, 

 are more finely facetted than those of //. filum, 

 and the tibiae are much less dilated at the end. 

 The punctures on the head and pronotum are 

 finer and more numerous, and the latter is a 

 J little shorter, being scarcely as long as it is 

 broad. The front and hind margins are gently 

 and evenly rounded, and the lateral margins nearly 

 straight. The antennae agree almost exactly with 

 those of H. filum, except that they are a very 

 little shorter. 



The occurrence of this genus is interesting. 

 Its numerous species are nearly all confined to 

 Tropical America, but one has been found in New 

 Zealand, one in Ceylon, one in Madagascar, and two 

 in the Seychelles.

Two specimens of an unknown species belonging to this family were found 

 at Malololelei. The late Mr. G. C. Champion, who made a study of the family 

 and examined these specimens, was not able to say whether they belong to any 

 recognised genus. 



EEOTYLIDAE. 



Monothallis, gen. nov. 



This genus is formed for TJiallis samoensis Heller, T. perplexa Blackb. 

 (Queensland), and T. xanthosticta Crotch (Gilolo, etc.), which differ from all 

 other Erotylidae known to me in the character of their stridulating apparatus. 

 I have already referred to this in a recent paper dealing with the subject of 

 stridulation {Trans. Ent. Soc. Lond., p. 135, 1924), in which the structure is
