INCALIA.— COEYNOPHILTJS. 53 



long and acute ; the apical tooth is long ; at the middle the mandible thickens towards 

 the base, and where the thickening commences the edge is indented. 



The genus Syzygonia (from Brazil) is very closely related to Incalia ; but may be 

 known by its bare, distinctly clavate, 6-jointed antennae. 



Syzygonia has the palpi 4- and 3 -jointed, as with Incalia. 



1. Incalia hirticornis. (Tab. III. figg. 6, $ ; 6a, antenna; 6 b, labium; 6 c, 

 tarsus and apex of tibia ; 6 d, maxilla; 6 e, head, from front.)

Subtribe LOBOCERIDES. 



Labium with three lobes. Labial palpi 4-jointed ; maxillary 6-jointed. Cubital ner- 

 vure issuing from the costa. Spines and calcaria usually sharp and long. 



COEYNOPHILUS.

 Corynophilus, Kirby, List of Hymen, i. p. 32. 



It is doubtful if the following species is congeneric with Klug's Cephalocera pumila, 

 for the radial cellule can scarcely be said to be appendiculated, nor can I detect any 

 traces of spines on the posterior tibiae ; but as the spines are apt to be broken off, no 

 great reliance can be placed on their absence on a single specimen. In the form of the 

 antennas it agrees very well with Corynophilus, as it does also in neuration (with the 

 above-mentioned exception), and it differs from Loboceras in the short thick spurs and 

 in the form of the antennas. I think it best therefore to treat the only species I have 

 as a Corynophilus. 



The type of the genus is from Brazil. 



1. Corynophilus ruficollis. 



Nigro-violaceus, antennis nigris, pilosis, prothorace mesonotoque cum scutello rufis, apice coxarum, trochante- 



ribus oreque sordide albidis ; alis fumatis. 

 Long. 6 millim. 



Sab. Panama, Bugaba (Champion). 



The antennas become gradually thickened towards the apex, and are about the length 

 of the thorax with the head ; the third joint is about one fourth longer than the 

 following, which is a little longer than the fifth ; the sixth is a very little longer than 

 broad ; last as long as the two preceding together. The sutures on vertex are deep 

 and reach to the antennas ; from the lower ocellus runs a suture to a transverse margin
