the trophi as described by Gyllenhal, Ins. Suec. 2, p. xiv., this genus 
most nearly approximates to 
UtetoTa, Latr. / Brontes, Fabr.) 
the type of which is the Br. flavipes of Fabricius. This genus is cha- 
racterized by the length of its antenne, (the second joint of which is 
inserted upon the side rather than the apex of the preceding joint, 
Tab. Supp. xxv, fig. 4, A), the acuteness of the last joint of its palpi 
(ibid. D. & E.), and its labium, which is merely emarginate in front, E. 
The male of the typical species presents a remarkable character in having 
the outer side of the mandibles armed with a strong bent hornlike process 
considerably advanced in front of those organs, (Ibid. C.). I do not find, 
from the description of this species, that the antenne of the female are 
shorter than those of the male; had they been so, Latreille would 
doubtless have mentioned the circumstance. 
To this genus evidently belongs an insect, considerably larger than the 
Ul. flavipes, brought by Dr. Horsfield from Java, and now contained in 
the Museum of the East India Company. Mr. Hope also possesses the 
same species from New South Wales. The British Museum Cabinet 
contains another species allied to Ul. flavipes. 
It will not be considered necessary for me further to mention the obvi- 
ous affinity between the last genus and 
Cucusus, Fab., 
which, as a genus, is characterized by Latreille by the comparative short- 
ness of its moniliform antenne (Tab. Supp. xxv1, fig. 5, A.), depressed 
body, truncate palpi (Ibid. D. and E.), and bifid abiwm (Ibid. E.) Such, 
indeed, are the characters presented by the large typical species, Cuc. de- 
pressus (sanguinolentus, Linn.,) and clavipes; but the genus, as at present 
constituted, comprises several distinct forms, to some of which I propose 
to advert. 
There is, however, another character connected with the typical 
species, namely, the real formation of the tarsi, which has escaped the 
notice of Latreille, notwithstanding he has, in the first edition of the 
Régne Animal, expressly characterized the tarsi as having all the joints 
entire, whilst, as belonging to insects placed by him in his division Tetra- 
mera, it is evident that he must have regarded them as only four-jointed-
