175. OMOPLANDRIA FUSCIPENNIS, new species 



Moderately shining; head and fourth and fifth visible tergites 

 black, the posterior margin of the latter rufescent, thorax and rest of 

 abdomen reddish brown, elytra yellowish brown. Antennae and legs 

 reddish yellow. Somewhat resembling in build the subgenus Acro- 

 tona Thorns. Head a good deal narrower than the thorax, eyes mod- 

 erate, longer than the postocular region, finely moderately closely punc- 

 tured, finely coriaceous, the disc in male slightly flattened. Antennae 

 short, the first two segments of equal length, third a little shorter 

 and narrower, fourth to tenth transverse, gradually increasing in 

 width, the penultimate 21/2 times broader than long, eleventh small. 

 Thorax transverse, twice as broad as long, the sides rounded, more 

 retracted in front, the posterior angles rounded, the disc in male 

 slightly flattened, the sculpture as on the head. El^^tra nearly twice 

 as long as thorax, broader than long (2.5 :2) , finely more closely punc- 

 tured, finely asperate, the ground sculpture very fine. Abdomen nar- 

 rowed toward apex, very finely, moderately closely punctured on 

 the anterior tergites, more sparingly behind, the ground sculpture 

 feeble. Male, first visible tergite on each side near the lateral margin 

 with a short, slightly curved pointed spine : fifth with a median keel 

 behind : sixth arcuately emarginate and crenulate in the middle of the 

 posterior margin with a small tubercle adjacent, elsewhere with a few 

 smaller scattered granules. Length, 2-2.5 mm. 



Type locality. — Formosa, Arisan. 



Types. — Holotype and 23 paratypes, U.S.N.M. No. 58744; two 

 paratypes in my collection ; two paratypes in the Gressitt collection in 

 the California Academy of Sciences (C. A. S. No. 5956). 



176. ALEOCHARA (s. str.) FORMOSAE, new species 



In size, build, and antennal structure similar to lata Gravenhorst 

 but differing as follows : The first three segments of the antennae and 

 the eighth tergite are reddish yellow, the puncturation of head and 

 thorax finer and not so close, the abdomen is distinctly more closely 

 punctured throughout, in other respects similar. From parens Sharp 

 it differs in the more robust build, much more finely and less closely 

 punctured head and thorax, coarser sculpture of the elytra, more 

 coarsely and rather more closely punctured abdomen. 



Type locality. — Formosa, Musha. 



Types. — Holotype, U.S.N.M. No. 58745; one paratype in my col- 

 lection ; collected V-18-32.
