WEEVIL GENUS MAEMACTES — KISSINGER 483 



antennae piceous. Sparsely clothed with suberect, fairly coarse, 

 somewhat yellowish setae. Rostrum stout, shorter than prothorax, 

 depressed throughout, coarsely densely punctate basad of insertion 

 of antennae, distad of this point mth sparse fine elongate punctures; 

 in dorsal view ratio of width of frons to widest point at base as 2:5, 

 ratio of width of frons to width of rostrum at antennal insertion as 

 2:3; in lateral view frons slightly flattened between base of rostrum 

 and head so that rostrum does not merge smoothly with head; head 

 with rather small, deep, moderately close punctures; eye acutely 

 oval, 0.56 mm. from top to bottom, 0.25 mm. wide. Prothorax 

 about as long as wide at base, sides expanding from base to widest 

 point near middle, there nearly one-fifth wider than base, rounded 

 to slightly constricted apex; pmictures very deep, very coarse, from 

 0.12 to 0.18 mm. in diameter, each puncture with a seta arising from 

 its side from a separate small puncture which has its inner wall 

 projecting into the cavity of the large puncture and its outer wall 

 shared with the large puncture; interspaces polished and shining, 

 with sparse minute shallow punctures, interspaces varying in size 

 from cariniform to quite wide, flat areas; no indication of median 

 impunctate area; postocular lobes feebly developed. Elytra 1.7 

 times as long as prothorax as 12:7; at widest point elytra nearly one- 

 fifth wdder than prothorax at widest point as 19:16; widest a little 

 behind basal third ; intervals narrow, equal to or sUghtly wider than 

 striae, all more or less convex, intervals 3 and 5 more prominent, each 

 with a single row of rather large punctures bearing suberect setae, 

 each seta about 0.12 mm. long and mostly linear but a few clavate; 

 punctures separated by about the length of a seta; striae complete, 

 broad, with large deep quadrate punctures and usually with a single 

 row of setae generally smaller than those on intervals, also an irregu- 

 lar lateral row located where stria merges with interval, this row com- 

 posed of usually narrow to (rarely) quite broad, scalelike setae. 

 Middle femur with a small tooth; hind femur with a distinctly larger 

 tooth; hind tibia mucronate on inner apical angle. Sternites deeply, 

 rather coarsely, and moderately closely punctiu-ed; male with sternite 



1 broadly shaUowly concave medially toward apical margin, with 

 suture between sternites 1 and 2 deep and straight medially, sternite 



2 distinctly shorter than sternite 5 when measured medially; female 

 with sternite 1 more convex toward apex, with suture between stern 

 ites I and 2 shallow and aiched medially, sternite 2 equal in length 

 to 5 when measured medially. Median lobe of aedeagus of male 

 as figured. 



Holotype male, Finca El Real, Ocosingo Valley, Chiapas, Mexico, 

 July 1-7, 1950, Goodnights and Stannard, from Andropogon clump, 

 USNM Type 65803. Allotype, same data as holotype, in author's 

 collection.
