PSEUDEUTOXUS.—CALANDROMIMUS., 363 
basal portion moderately developed and almost covering the flattened mososternum ; anterior coxze 
separated by about their own width in the ¢, more distant in the 2; legs long and slender; femora 
clavate; body elongate-rhomboidal, polished, almost glabrous above, the tibia and tarsi more or 
less pilose. 
Type, Ps. filirostris, 
This genus includes a single species from Costa Rica, with remarkable sexual 
distinctions. The very slender, long, flattened rostrum, with shallow, laterally-placed 
scrobes, the peculiarly-formed mandibles of the female, the short basal lobe of the 
prothorax, and the free scutellum, separate Pseudeutorus at once from Eutoxus. In 
the present genus, too, the female has an extremely elongate rostrum, it being more 
than twice as long as in the male—a character to be found in various Balantne. 
1. Pseudeutoxus filirostris, sp. n. (Tab. XVIII. figg. 21, 2la,¢; 22, 
22 a, 2.) 
Shining, black; clothed with scattered, fine, golden hairs beneath, these being long and conspicuous on the 
under side and flanks of the prothorax. Head finely punctate, foveate and transversely grooved between 
the eyes; rostrum shallowly grooved down the middle and finely punctate in the ¢, smooth and unim- 
pressed in the @. Prothorax transverse, arcuately narrowing from the base to the narrow anterior lobe ; 
closely, finely punctate. Elytra wider than the prothorax, rapidly narrowing from the base; flattened 
anteriorly, each with a deep, oblique, foveiform depression on the disc at one-third from the apex; 
sharply striate, the strie obsoletely punctate, the interstices almost smooth, flat, the second depressed 
along the short apical declivity. Beneath very sparsely, finely punctate; intercoxal portion of the 
prosternum tumid in the middle in the 2, hollowed in the ¢; first ventral segment very broadly 
excavate, and the fifth with a transverse densely pilose depression, in the ¢. Anterior tibie sinuous, 
dilated in their apical two-fifths, and unarmed at the apex in the g, gradually widened to the apex and 
with a long terminal claw in the 9. Anterior tarsi with long projecting hairs in the g. 
Length 54-7, breadth 21-3 millim. (¢ @.) 
Hab. Costa Rica, Rio Sucio and Irazu (fogers). 
One female and two males. 
CALANDROMIMUS, gen. nov. 
Rostrum flattened, feebly curved, very little longer than the head and prothorax, the scrobes rapidly descending, 
becoming shallow and coalescent beneath, the antenne inserted slightly beyond the middle, the antennal 
club small, ovate; mandibles blunt and slightly decussate at the tip ; head small ; eyes large, transverse ; 
prothorax with a short, abrupt neck in front, the basal lobe truncate ; scutellum large, free, flat, trans- 
versely subquadrate; elytra oblong-triangular, wider than the prothorax, sharply striate; pygidium not 
visible; pro-, meso-, and metasternum and abdomen broadly excavate or flattened down the middle for 
their entire length; prosternum with a fine arcuate groove between the widely-separated, exserted 
anterior cox, the broad basal process shallowly arcuate-emarginate behind and on the same plane as the 
flattened intereoxal portion of the mesosternum; mesothoracic epimera broad and ascending, the upper 
portion visible from above; metasternum with a narrow median sulcus; ventral segments 1 and 2 
connate in the middle; femora unarmed, curved, compressed, strongly clavate, the anterior pair very 
stout; tibiae somewhat curved, flattened, acutely produced at the inner apical angle in the ¢; tarsi 
comparatively slender, the claws free; body elongate-elliptic, bread, flattened above and beneath, sparsely 
squamose. 
Type, C. caviventris.
