less than one half longer than wide, scarcely as wide as the prothcrax and one- 
half longer, evenly rounded at apex, the punctures minute and sparse, those of 
the series larger and closer. Length I 0-1.2 mm ; width 0.4-0 5 mm - Florida.

,I_Narrowly cylindric-oval, moderately shining, pale flavo-testaceous throughout; 
head and eyes well developed, the front concave; clypeal process narrow, long, the 
apex strongly rounded ; prothorax distinctly wider than long, the apex evenly and 
circularly rounded, the sides becoming parallel toward base; punctures very minute, 
sparse and feeble ; base distinctly margined as usual; elytra fully as wide as the 
prothorax and two-thirds loDger, not quite one-half longer than wide, parabolic- 
ally rounded at tip, margined at base, the punctures sparse, very feeble and ex¬ 
tremely minute, even smaller than those of the prothorax; .surface smooth. 
Length i.o-l.i mm.; width 0.4-0.45 mm. Florida. unicorne, sp. nov. 
Unicorne is evidently closely related to the Brazilian corniferum of 
Mellie, but in that species the cephalic process is said to be broad, re- 
curved and narrowed to the acute apex. 
Ceracis Mellie. 
This genus is scarcely distinct from Ennearthron , agreeing in facies 
and in every structural feature except the antennae, which are S-jointed, 
one of the small joints of the funicle being eliminated. The swo species 
before me are as follows:— 
Rufctestacecus, the elytra blackish toward base ; punctures very minute and sparse, 
the remaioing characters nearly as in pundulata. Louisiana [Mellie], Nort 
Carolina and Pennsylvania (Westmoreland Co.). . Sa *. ^ * 
Black throughout, the head and prothorax sometimes picescent; legs, trophi and an- 
tenure pale ; surface polished, the elytra nearly smooth ; head and eyes well de¬ 
veloped ; clypeal process rather well developed, with its sides but slightly con¬ 
verging, the apex broadly sinuato-truncate ; prothorax slightly shorter than wide, 
the sides feebly convergent and broadly arcuate from the base to the rather pro¬ 
nounced but obtuse apical angles ; process very abruptly formed, moderate in 
length, the exterior angles somewhat everted and the apex deeply sinuate; 
punctuation quite deep and close set but rather fine; base finely margined; 
elytra at base as wide as the proihorax, less than one half longer than wide; 
the sides nearly straight and feebly convergent; apex broadly rounded, base not 
in the least margined ; punctures finer and sparser than those of the prothorax, 
confusedly arranged. Length 1.25-1.3 mm.; width o 55-0.6 mm. 
punctulata, sp. nov. 
The species recently described from Lower California by Dr. Horn, 
under the name similis, appears to resemble sallei, but differs from 
both the above in having the elytral punctures coarser than those of the 
prothorax, a very exceptional character in Ennearthron and Ceracis.
