LOBOCEEAS. 57 



less testaceous; the last joint of the antenna? is longer than the preceding; the third 

 cubital cellule is a little longer than broad ; the second recurrent nervure is inter- 

 stitial. The blotch is large and white. 



7. Loboceras fascipenne. (Tab. I. fig. 6, $ .) 



Luteum, antennis, eapite (ore excepto), abdominis apice, tarsis tibiisque nigris ; alia fuscis, eellula secunda 



cubitali puncto corneo oblongo, costa et stigmate nigris. 

 Long. 7£-8 millim. 



Hah. Panama, David {Champion). 



The antennae are densely pilose, nearly as long as the abdomen, and become 

 thickened very gradually towards the apex ; the last joints subequal. The face below 

 the antennae is pale testaceous ; the clypeus is very slightly incised ; the apex of the 

 mandibles piceous. The second cubital cellule is double the length of the third, which 

 is not much longer than broad ; the first recurrent nervure is received close to the 

 middle of the cellule ; second close to the base of the third cellule ; the transverse 

 median in front of middle of cellule. There is a distinct horny point in the costal and 

 second cubital cellules. Sometimes the second recurrent nervure is received in the 

 second cubital cellule. The anterior tibiae are fuscous behind ; the spurs are long and 

 sharp. The frontal sutures are deep and wide, the frontal area somewhat depressed in 

 the centre ; the front bears scattered punctures. Sometimes there is a black longish 

 mark on the middle lobe of the mesonotum. The base of the antennae and the part 

 immediately above it testaceous. 



8. Loboceras nigriceps. 



Luteum, pilosum, ovatum, antennis, eapite (ore excepto), tegulis, abdominis apice, tibiis tarsisque nigris; alis 



fuscis, costa nigra, stigmate fusco, nervo primo cubitali nullo. 

 Long. 5 millim. 



Hah. Mexico (Salle). 



The antennae are short, not much longer than the thorax, thick, tapering very slightly 

 towards the apex ; the third joint is a little longer than the fourth ; the last joint is 

 longer than the sixth, which is shorter than the fifth. The frontal sutures are almost 

 invisible; there is no frontal area, nor is there a furrow behind the lower ocellus. 

 The transverse median nervure is received immediately in front of the cellule, the 

 second recurrent in the same position. The anterior tibiae are faintly fuscous in front, 

 the four posterior are entirely black ; the extreme apex only of the abdomen is black. 



This species is readily known from L. fusdpenne, which it resembles very closely 

 in coloration, by being smaller, by its more ovate body, by the first transverse cubital 

 nervure being absent, or at least scarcely to be distinguished, by the shorter spurs 

 (which are black and not half the length of metatarsus), by the second recurrent 

 nervure being received nearer the middle of the cellule, by the second (first) cellule 

 wanting the horny point, and by the black tegulae.
