419 -Mr. A. Murray on Coleoptera from Old Calabar. 
^. Very like P. obscura; but the colour of the pubescence is 
bluish grey instead of ash-grey, and the black markings on 
the elytra are more distinctly m bands—the second band be- 
hind the middle being the longest, but reaching neither to the 
suture nor the external margin, waved and broadest next the 
suture; the other marks only a little longer than in P. obscura. 
The thorax has the raised parts more distinct and flat on their 
surface. 
Not frequent. 
PHRYSTOLA*, nov. gen. vel subgen. 
The species on which I have founded this genus or sub- 
genus is closely allied to Phryneta and Pachystola. M. Chev- 
rolat described it as a Phryneta; but the facies is not that of 
Phryneta, being less robust and more elongate. It is nearer 
the form of Pachystola, but more convex on the back (Pachy- 
stola has the back somewhat depressed). The antennz in bot 
Phryneta and Pachystola are short, rarely exceeding the body 
in length. In this insect they are longer than it, and, what 1s 
of more importance, they have not the wire-like uniform thick- 
ness of Pachystola nor the flatter thickness of Phryneta. The 
are, like the antenne in Prosopocera, rather fine, especially to- 
wards the apex, and each article defined by being a little 
thicker at the apex ; the first article, however, is, like that of 
hryneta, rounded in at the apex, and with scarcely any cica- 
trice. The head is hollowed between the antenne, and raised 
on each side at their base. The thorax is more elongate than 
very broad, intermediate equal. Tubercle of the 
sternum smaller than in most of the species of Phryneta and 
Pachystola. In other respects it corresponds with Phryneta. 
Phrystola ceca. 
Phryneta ceca, Chevr. Rev. et Mag. d. Zool. 1857, p. 75. 
Cinerea, obscura, nigro signata; capite lato, antice recte trun- 
cato, suleo longitudinali angusto; mandibulis oculisque 
(postice einereo marginatis) nigris; antennis gracilioribus, 
corpore vix longioribus, infra parce pilosis, nigricantibus ; 
thorace cinereo, in medio et lateribus nigricante, antice 
recto, basi profunde bisinuato, anguste trisulcato, in mec 
dorso tuberculum oblongum antice trinodosum et longitudine 
* Name compounded of Phryneta and Pachystola, in allusion to its 
partaking of the characters of both. : ae
