narrowly rounded, sides feebly arcuate and somewhat converging 

 anteriorly; the eyes occupying a fourth of the sides; antennae as 

 long as head ; with fine obsolete sparse punctures, lacking along the 

 middle; the intervals with ground sculpture. Pronotum as long 

 as head but distinctly narrower, the sides subemarginate and scarcely 

 diverging to front, the anterior angles narrowly rounded, the pos- 

 terior broadly, the base feebly arcuate; with six posteriorly diverg- 

 ing rows of 9 to 10 fine punctures, and a few others anterolaterally. 

 Elytra a little longer than pronotum, somewhat dilated behind, the 

 humeri prominent, the sides straight; with punctures stronger, 

 coarser, regular and not dense. Abdomen with punctures very fine 

 and sparse. Length, 3 mm. (From Bierig.) 



Type locality. — Cuba, El Kangel, Sierra del Rosario. 



Types. — A unique female in the collection of Alexander Bierig. 



Records. — The following is the only record known to me : 



Cuba: EI Rangel (Bierig, 1937). 



Specimens examined. — I have seen no examples of this species. 



Remarks. — The relationships of this species are unknown to me 

 except from the remarks of Sr. Bierig and the fact that it does key 

 out to Oligolinus (which is the true name for the Metoponcus men- 

 tioned by Bierig). 



The type was found beneath loose bark of a fallen mastic tree 

 (Almacigo). 



LXXXIV. Genus OLIGOLINUS Casey 



Oligolinus Casey, 190G, p. 372. 



Genotype. — Metoponcus floridanus 'LeCont(i= Oligolinus floridantts 

 (LeConte) (monobasic and original designation). 



Diagnosis. — Head very sparsely punctured; antennal grooves obso- 

 lete; ocular grooves more or less distinct; antennae inserted close 

 together at front of head, basal segment not over one-third as long 

 as head, outer segments not densely pubescent; labrum very small, 

 not distinctly emarginate; maxillary palpus moderately long, fourth 

 segment much shorter than third, conical; fourth segment of labial 

 palpus slender; gular sutures obsolete; neck generally much less than 

 one-fourth as wide as head; lateral margin of pronotum double but 

 the lines united near middle on under side ; prosternum with a sclerite 

 in front of sternite; elytral suture beveled; middle coxae narrowly 

 separated; posterior coxae narrowly separated, "triangular"; first and 

 second abdominal sternite absent; intersegmental membrane of abdo- 

 men marked with a pattern of angular areas in longitudinal bands. 



Remarks. — This genus has been confused in America with Meto- 

 poncus Kraatz. It is restricted to tropical and subtropical America
