2. MEDON MATASANA, new species 



Description. — Piceocastaneous, humeri and sides of abdomen some- 

 Avhat paler. Head exclusive of eyes about one-sixth wider than long, 

 base slightly emarginatc over the neck, sides very feebly converging 

 behind, the angles narrowly rounded; eyes large, at about their length 

 from base; labrum with a small but abrupt emargination deeper than 

 wide, without denticles; gular sutures fairly close and nearly parallel 

 from near the front ; with dense but rather small umbilicate punctures 

 interspersed with larger ones; the intervals flat and without distinct 

 ground sculpture. Pronotum about one-sixth wider tlian long, about 

 one-tenth narrower than head; sides moderately converging and 

 rounded into base; disk feebly impressed along midline posteriorly; 

 midline narrowly and indefinitely smooth and shining, vaguely 

 canaliculate posteriorly; w^ith very dense and irregular umbilicate 

 punctures, the intervals not wide enough to be flattened; without dis- 

 tinct ground sculpture. Elytra with rather dense submuricate punc- 

 tures obscured by surface rugosity; with rather long pubescence. 

 Abdo?n^n finely and moderately densely punctate; with indistinct 

 ground sculpture. Male, eighth sternite with a large triangular 

 emargination, twice as broad as deep, with all angles rounded. Female^ 

 sternites unmodified. Length, 4 to 4^2 mrn. 



Type locality. — Dominican Republic, San Jose de las Matas, 

 elevation 1,000 to 2,000 feet. 



Types. — Holotype and seven paratypes in the Museum of Com- 

 parative Zoology; five paratypes in the United States National Mu- 

 seum (No. 52511) ; collected in June 1938 by Dr. P. J. Darlington. 



Records. — The following are the records known to me: 



Hispaniola: Dominican Repibi.ic, San Jost^ do las ilatas (Darlington, in M.C.Z. 

 and U.S.N.M.), Mount Quita-Espnela (Darlington, in M.C.Z. and U.S.N.M.), 

 Santiago de los Caballcros (Darlington, in M.C.Z.) , Villa Altagracla 

 (Darlington, in M.C.Z.), Sdnchez (Darlington, in M.C.Z.). 



Specimens examined. — I have seen only the 13 types. 



Remarks. — This species is distinct by its labral emargination, the 

 punctation of the pronotum and elytra, and the male characters. It 

 is larger than any of our species except dominicanum. It apparently 

 belongs in the subgenus Medon s. str. 



I have received no record of its habits.

 cially above the neck, sides parallel but moderately rounded into base; 

 eyes large, at a little more than their length from base; labrum with
