228 HETEROMERA. 
3. Ozolais nodosa. 
Broad ovate, subparallel, brownish-black, the upper surface coarsely tuberculate and clothed with greyish-brown 
scale-like hairs. Head with the antennary orbits swollen and extended laterally ; a small longitudinal eleva- 
tion in the centre of the epistoma in front and a stronger transverse one on the vertex in the male ; antenns 
much as in O. lutosa, the tenth joint exhibiting a dividing suture (the apical portion narrowed) ; prothorax 
rather broader than long, the sides obliquely converging from the base, irregularly crenulate, and with a 
broader irregular prominence on each side about the middle, the anterior angles broad and directed 
* forwards, the hind angles broad and directed outwards, disc strongly gibbous (as in O. lutosa), the surface 
(the discal elevations especially) with numerous scattered small bare granular tubercles ; elytra rather 
short, distinctly narrower than the prothorax at the base, subparallel to beyond the middle, with irregular 
rows of coarse tubercles, upon each of which is a small bare granular elevation (the tubercles smaller, 
more conical, and more numerous at the sides); beneath slightly shining, irregularly punctured ; pro- 
sternum distinctly produced ; legs, antennsz, and oral organs more or less ferruginous. 
Length 6} millim. (¢.) 
Hab. Nicaragua, Chontales (Belt). 
One male example. Shorter than 0. elongata, the sides of the thorax more oblique, 
the club of the antenne differently formed, &c. 
4. Ozolais elongata. (Tab. X. figg.11,¢; 11a, antenna; 114, side view of 
the head.) 
Elongate, subparallel, black, the upper surface coarsely tuberculate and densely clothed with greyish-brown 
scale-like hairs. Head with the antennary orbits swollen, raised, and extended laterally; a stout 
conical tubercle in the centre of the epistoma in front and a broad horizontal plate (widened out on 
each side at the apex) on the vertex in the male, a transverse elevation (upon which are two smooth 
granular prominences) on the vertex in the female; antenne 11-jointed, the first joint very stout 
and long, the second joint short and subglobose, the third ovate and about twice the length of the 
second, the fourth much shorter than the third, joints 5-7 slightly shorter than the fourth and 
about equal, the eighth joint the length of the seventh but a little wider at the apex and subtrian- 
gular, the ninth joint about twice the length and breadth of the eighth, widening a little outwardly, sub- 
quadrate, and rather widely separated from the tenth, the tenth joint the width of the apex of the ninth, 
distinctly divided in the middle (the subconnate eleventh joint clearly visible) into a broad transverse 
piece and a narrower portion rounded at the apex, ferruginous, the intermediate joints more or less 
infuscate ; prothorax not much broader than long, the sides narrowing from the base, coarsely and irregu- 
larly crenulate, and slightly constricted before and strongly so behind the middle, the anterior angles 
broad and projecting forwards, the posterior angles broad and directed outwards, the disc strongly gibbous 
(as in O. lutosa), the entire surface with scattered small bare granular tubercles (which are much more 
crowded and numerous on the discal elevations); elytra long, about the width of the prothorax at the 
base, subparallel to beyond the middle, with irregular rows of large and small rounded tubercles (the 
larger elevations more widely separated and placed principally on the disc) upon each of which is a small 
bare granular prominence; beneath slightly shining, longitudinally wrinkled; prosternum slightly 
produced. 
Length 8-9 millim. (¢ 9.) 
Hab. Nicaracua, Chontales (coll. F. Bates, Belt). 
Three examples. This species will be identified by the structure of the antenne, and 
by the cephalic armature of the male.
