136 Mr. Arthur M. Lea's Revision of the 



name must fall. There are, however, so many species 

 having the 10th and 11th joints curiously distorted (all on 

 the same plan though differing greatly in degree) in the 

 male, that I hesitate to regard the two names as synony- 

 mous. In his description, Blackburn says "femorihis 

 tihiisque (anticis totis, ceteris ex parte) testaceis." I have 

 only seen four specimens of gagaticeiis having the legs so 

 coloured, all the others (several hundreds) having the legs 

 as in my own description ; if therefore gagaticcj'ts really 

 belongs to galeatus, it is the typical form of a species of 

 which only a rare variety was known to Blackburn. 



The difficulty is not diminished by the fact that there 

 are before me three specimens of one species, and one of 

 another,* which also agree with the description of galeattis 

 as to colours and sculpture ; tliey are, however, certainly 

 different to gagaticeps as the 10th joint of the antennae is 

 much longer (in the male of gagaticeps it is decidedly 

 transverse), whilst the 11th is considerably longer and 

 thinner. In one of these species the antennae also are 

 about one-third longer, and the 3rd joint has an infuscate 

 spot on its upper surface ; in the other the antennae are 

 of the same length and colours.

In the type male the 9th joint of the antennae is greatly 

 inflated and has a deep apical fovea. A male from 

 Galston has the 9th joint also inflated but to a less 

 noticeable extent, and the fovea is also smaller. A male 

 from Launceston agrees with the Galston specimen in the 

 9th joint, but has the legs entirely dark. 



The elytral punctures are rather coarse and almost 

 regular, but become very small at the apex.

* As either of tliese may be the true galeatus, I have not described 

 them.
