This genus is allied to Synaphaeta Thompson, but differs from it 

 in having the cheeks shorter, the head only feebly depressed be- 

 tween the antennal tubercles, the eyes not wider than long, and 

 more coarsely granulated, the antennae shorter, not as strongly 

 ciliate, and the first joint subequal in length to the third, the elytra 

 not flattened above, more even, regularly convex at the sides and 

 without lateral carinae. 



LIOSYNAPHAETA BALLOUI. new species 



Male. — Form elongate, broad, regularly convex above, and densely, 

 irregularly variegated with moderately long, recumbent, cinereous, 

 and ocherous pubescence, forming no regular designs, and orna- 

 mented with a narrow brown margin around scutellum, and a nar- 

 row longitudinal sinuate spot of the same color on each elytron just 

 behind the middle; beneath rather densely clothed with yellowish- 

 white pubescence, and with a large triangular brown spot on the 

 middle of each abdominal segment. 



Head slightly wider than long, and nearly flat in front, feebly, 

 broadly concave between the antennal tubercles, which are very 

 widely separated and only slightly elevated, the surface finely, 

 densely punctate, with a few coarse, irregularly placed punctures 

 intermixed, a narrow longitudinal groove extending from the epis- 

 toma to occiput, and a small obtuse gibbosity on each side of the 

 middle between the eyes; eyes large, covering half the distance 

 between the antennal tubercles and front margin of head, separated 

 from each other on the top by one and one-half times the width of 

 the emargination of the eyes in front, and the two lobes connected 

 by a narrow band without facets. 



Pronotum one-third wider than long, and the apex and base about 

 equal in width ; sides nearly parallel, Avith a large, moderately acute 

 tubercle at apical third ; surface uneven, Avith three large, feebly ele- 

 vated tubercles on the disk, placed two in front and one behind, and 

 on each side a more strongly elevated tubercle, placed obliquely 

 behind the lateral tubercle, and finely, densely punctate, with a few 

 very coarse punctures scattered over the surface. Scutellum wider 

 than long, and very broadly rounded behind. 



Elytra three-fourths longer than wide, and distinctl}^ wider than 

 the pronotum; sides feebly obliquely narrowed from base to near 

 apex, more arcuately attenuate posteriori 3% and the tips broadly sub- 

 Iruncate; surface nearly even and regularly convex, the suture 

 slighty elevated near apex, and each elytron broadly tumid near the 

 base, densely and obsoletely punctate, with a few very coarse, irreg- 

 ularly placed punctures intermixed. Beneath finely and densely 

 punctate, and the last abdominal segment broadly arcuately emar- 

 ginate at the apex.
