SOME ENDOMYCHID BEETLES — STROHECKER 387 



joint 8 beadlike, joints 9 and 10 each about as broad as long, joint 11 

 oval, a little shorter than 9 and 10 together. Pronotum very trans- 

 verse, its sides strongly rounded behind the front angles, parallel in 

 posterior half; raised margin broad, narrowed posteriorly; basal 

 f oveae deep ; basal sulcus broad and deep and continued obliquely to 

 the hind angles. Disk of pronotum evenly, moderately convex, min- 

 utely and sparsely punctured, its pubescence sparse and erect. Scutel- 

 lum transverse. Elytra three times as long as pronotum, as wide at 

 base as pronotum, thence gently and slightly widened, gradually con- 

 vergent to apex, moderately convex, coarsely, sparsely and shallowly 

 punctured, pubescence sparse and semierect. The elytra are shining 

 and black except a very narrow basal border, a wider sutural stripe 

 and a still wider marginal stripe, which are red. The red areas are 

 continuous with each other. Length 3 mm. 



Type.— Male, U.S.N.M. No. 55885. 



Type locality. — Ma-Ao, Occidental Negros, P. I., at light (W. 

 Dwight Pierce). 



An unusual type among the oriental species of Stenotarsus. Its 

 general appearance is strikingly similar to that of S. militaris 

 Gerstaecker from Mexico, except the new species lacks the black patch 

 on the pronotum. 



STENOTARSUS FLAVOMACULATUS, new species 



Long-oval, strongly convex, black and moderately shining with the 

 umbo, an anterior juxtasutural spot and a postmedian transverse bar 

 on each elytron reddish yellow. Antennae a little longer than head 

 and pronotum, black except for the first two joints and apical half of 

 the last, which are piceous; joints 2 and 8 about as long as broad; 

 joints 3 to 8 subequal in length but progressively stouter; joints 9 

 and (especially) 10 transverse, little flattened; joint 11 oval, about as 

 wide as long. Head finely and sparsely punctured. Pronotum 

 abruptly and strongly convex, finely and sparsely punctured with 

 correspondingly sparse pubescence ; raised margins moderately broad 

 and much deflexed at the front angles ; hind angles right ; basal f oveae 

 very deep, grossly punctif orm ; basal sulcus shallow, marked by a row 

 of coarse punctures close to base of pronotum. Scutellum oval, trans- 

 verse. Elytra highly but not abruptly convex, rather coarsely and 

 sparsely punctured, pubescence sparse; umbones inflated, entirely 

 reddish yellow. The juxtasutural spot has vague outlines but is 

 broadest internally and triangularly narrowed toward (or to ?) the 

 umbo. The postmedian bar is concave anteriorly, convex posteriorly 

 and extends from the lateral margin almost to the suture. Under sur- 

 face, including legs and elytral epipleurae, pitchy red. The epipleurae 

 are coarsely punctured. Length 2.5 mm., width 1.5 mm.
