66 NEW ROSTRATED LOCUSTID A. 
The insect represented in the lower figure constitutes a new 
genus, which, notwithstanding the great size of the frontal pro- 
minence, I arrange in Serville’s section Conophori, and to which 
may be applied the generic name of 
BACTROPHORA, W. 
Corpus elongatum subcylindricum ; caput magnum, oculis magnis prominentibus, fronte in 
baculum (capite fere duplo longiorem) cylindricum, infra carinatum producto. Antenne 
prothoracis longitudine, 24-articulate, parum compress, articulis 3tio et proximis bre- 
vissimis et tenuioribus; inter et prope oculos ad basin rostri inserts. Facies infra 
valde tumida; labrum maximum bilobum.  Prothorax tuberculatus, absque carina 
dorsali, canalibus duobus transversis impressus. Pedes 4 antici breves. Prosternum 
dente brevi obtuso armatum. 
BACTROPHORA DOMINANS, W. (PI. 17, fig. 2.) 
Tota luteo-fulva, antennis (articulis 2us basalibus exceptis) nigris, tegminibus fusco-nebulosis 
alis apice fuscis. 
Long. corp. rostro incluso unc. 33. Long. rostri ante oculos =$; unc. Expans. tegm.

The produced front,of the head forms a snout somewhat like that of some species of Fulgora, 
ascending a little from the impressed arched channel between the eyes ; the under side is rather 
rugose, and along the centre runs a carina which terminates in the acute arched, rather dilated 
apex: this carina at its base is fureate, each branch extending to the base of one of the an- 
tenne ; the pronotum is covered with small tubercles, which even extend along the anterior 
margin, two being of larger size in the middle. The tegmina are opake and very closely reti- 
culated ; they are of the same colour as the rest of the body, but are clouded with many small 
patches of brown ; the wings are pale fulvous at the base, with the apex dark brown. 
I regret that the locality of this extraordinary and unique insect 
is unknown. 
The plant figured is part of a twig of Combretum comosum, a 
splendid species found at Sierra Leone.
