AMMOPHORUS COOKSONI, Sp. Nn. 
Oblongus, ater, vix nitidus ; capite lato, planato, crebre fortiter 
longitudinaliter ruguloso-punctato: thorace quam caput + la- 
tiore, latitudine quam longitudo 1 majore, sat convexo, con- 
fertim fortiter punctato, antice posticeque oblique angustato, 
lateribus medio subparallelis, angulis anticis subacutis promi- 
nulis, posticis acutiusculis vix divaricatis ; elytris basi thorace 
haud latioribus, postice paulo ampliatis, convexis, fortiter late 
sulcatis, sulcis seriebus punctorum magnorum transversim im- 
pressis, interstitiis angustis cariniformibus, nitidis; humeris 
denticulo acuto armatis; pedibus brevibus obscure piceis, tibiis 
asperatis. Long. 3 lin., lat. 13 lin. 
This species is closely allied to A. obscurus, G. Waterh., but is 
relatively broader. The 4th to the 11th joints of the antenne are 
very strongly transverse ; the forehead is more strongly punctured ; 
and the interspaces are inclined to form rugule, especially near the 
eyes. The thorax is more strongly punctured, about } broader than 

long (whereas in A. obscurus it is only as broad as long) ; the sides 
are more sinuous. The coste of the elytra are more pronounced, 
and the channels are more slightly punctured. The legs are shorter 
somewhat and rough.

Antenne approximate at their base. Claws simple. Cotyloid 
cavities for the anterior coxze open. Prothorax marked posteriorly 
with a transverse impressed line, not bounded on each side by the 
short longitudinal impression. Posterior femora not reaching to 
the extremity of the elytra. Basal joint of the posterior tarsi as long 
as the two following joints taken together; the 2nd and 3rd joints 
about as long as broad. 
The position of this genus appears to me to be next to Graptodera.
