comb along their inner edge, 4 small; posterior tibiz curved.

median lobe drawn out into a Jong, slender, curved point.

There are five males and three females of this species in 
the Museum, including a 2 from Abyssinia received in 1855. 
A hairy, elongate insect, black or piceous, with the pro- 
thorax and tarsal claws, and usually the scutellum also, 
testaceous, the elytra with a faint bluish tinge ; the antennal 
joints 3-10 elongated and slightly widened, 11 curved, 
hollowed on its inner face, much longer than 10 in ¢. 
The faintly mdicated elytral coste are exaggerated in 
Reiche’s figure. J. fulvicollis has the antenne less widened 
than in J. dimidiata, both species occurring at the same 
locality in Abyssinia. J. henondi, Fairm., from Choa (1883), 
may be a form of the 2 with an infuscate prothorax? The 
genital armature is very like that of J. dimidiata and 
L. plectrophora.

Very elongate, somewhat widened posteriorly, shining, 
the elytra rather dull; finely pubescent and sparsely nigro- 
setose; fulvous, the head (the labrum and epistoma ex- 
cepted) and the antennz from about the fourth joint black, 
the elytra with a large apical patch (occupying one-third or 
more of their length) nigro-cyaneous. Head long, narrow, 
strongly produced anteriorly, the labrum about as long 
as broad, hollowed down the middle; eyes very large, 
moderately convex, subcontiguous in g’, narrowly separated 
in ?; antenne long in @, a little shorter in 9, joints 5-10 
elongate, feebly serrate, moderately widened, subequal in 
length, 11 concave within, slightly longer than 10. Pro-
