LIMNOBARIS. 393 
One male, probably somewhat worn. An elongate, narrow form, with the prothorax 
about as long as broad and the elytra maculate with white scales across the base and 
at the middle of the disc towards the apex. 
18. Limnobaris manducator, sp. n. 
Elongate-ovate, somewhat convex, narrow, shining, rufescent; clothed with a few long, fine, scattered, 
yellowish, hair-like scales, which are clustered into a stripe along the sides of the prothorax and down the 
base of each of the elytral interstices. Head sparsely, very minutely punctate, with a deep transverse 
groove between the eyes ; rostrum arcuate, nearly as long as the head and prothorax, closely, very finely 
punctate, smoother along the middle of the basal half, the antenne inserted midway, the antennal club 
short-ovate, stout. Prothorax about as long as broad, feebly constricted in front, the sides rounded 
anteriorly and parallel towards the base; finely, closely punctate, except along the narrow, abbreviated, 
impunctate, median space. Scutellum small. Elytra oblong, scarcely wider than the prothorax, 
depressed along the suture below the base; finely punctate-striate, the interstices each with a row of 
minute scattered punctures. Beneath closely, the ventral segments 2-4 more sparsely and finely, 
punctate. Prosternum unimpressed behind the deep transverse subapical groove. Anterior coxe 
separated by about their own width. Anterior tibiee with a long, the others with a shorter, hook. 
Length 23, breadth ;* millim. (7%) 
Hab. Mexico, 'Toxpam (Sai/é). 
One rather worn specimen, probably a male, though the first ventral segment is 
unimpressed. Smaller and smoother than L. lewcostigma, the elytra more finely striate 
and immaculate beyond the middle, the vestiture much finer. ‘The mandibles are 
acutely dentate within. A somewhat similar unnamed form from Brownsville, ‘Texas, 
has been sent me by Mr. Wickham. 
19. Limnobaris zneola, sp. n. 
Elongate-ovate, narrow, «neous, moderately shining; sparsely clothed above and beneath with short, fine, 
hair-like, whitish scales, those on the elytra arranged in a single series down each interstice. Head 
transversely grooved between the eyes; rostrum curved, moderately stout, scarcely so long as the 
prothorax, and closely punctate—in the @ a little longer, smoother, and more slender,—the antenne 
inserted at about the middle. Prothorax slightly broader than long, narrowed and feebly constricted in 
front ; rather closely punctate, except along the median line, the interspaces finely alutaceous. Scutellum 
narrow. Elytra a little wider than the prothorax, oblong, conjointly rounded at the apex, depressed 
along the suture below the base ; finely striate, the strie becoming deeper and distinctly punctate at the 
apex, the interstices flat and obsoletely punctulate. Beneath coarsely, the middle of the metasternum 
and the abdomen more sparsely and finely, punctate; metasternum at the apex and first ventral segment 
hollowed down the middle in the ¢. Prosternum without trace of depression. Anterior coxe rather 
narrowly separated. Legs short; femora moderately stout, the tibise and tarsi slender; anterior tibie 
strongly unguiculate in the ¢. 
Length 13-2, breadth # millim. (d @.) 
Hab. Mexico, Motzorongo (U.S. Nat. Mus.: 3), Teapa (4. H. Smith: 3); 
GuaTemMALA, Tamahu in Vera Paz (Champion: ¢ @); Panama, Volcan de Chiriqui 
(Champion: ¢ ). 
Thirteen specimens, nine of which are from Vera Paz. A minute, narrow, eneous 
form, clothed with scattered, fine, hair-like, whitish scales, which are seriately arranged
