the apex, depressed along the suture at the base; sharply striate, the striz feebly punctate, the interstices 
flat, twice as wide as the stris, uniseriate-punctate, the punctures minute or almost obsolete on the 
glabrous spaces. Beneath closely, the ventral segments 1-4 rather sparsely, punctate, 1 hollowed down 
the middle in the ¢. Prosternum unimpressed. Anterior coxe separated by less than their own width. 
Tibiz strongly unguiculate, 
Length 23-22, breadth 15-1} millim. (d Q.) 
Hab. Mexico, Jalapa (Hége: 3); Panama, Tolé (Champion: 2 ). 
In this insect the elytra look as if they were rubbed on the disc, but this is not the 
case, the broad bare space, which extends for some distance down the suture posteriorly, 
being similarly shaped in the two examples obtained. 
16. Limnobaris truquii, sp.n. (Tab. XVIII. figg. 6, 6a, 2.) 
Oblong-ovate, flattened above, shining, piceous, the prothorax and elytra at the sides, the tip of the rostrum, 
antenne, and legs more or less ferruginous; the prothorax with a spot at the middle of the base and a 
broad marginal stripe on each side, and the elytra (a large, common, rounded patch on the anterior part 
of the disc excepted), somewhat thickly clothed with coarse, oblong, brownish-white scales, the under 
surface and legs rather sparsely clothed with narrow similarly-coloured scales. Head and rostrum as in 
L. discreta. Prothorax coarsely, densely punctate, except along the smooth median line. Scutellum 
squamose. Elytra deeply punctate-striate, the interstices about as wide as the strie and rather coarsely 
uniseriate-punctate throughout. Beneath closely punctate. Prosternum unimpressed. 
Length 23, breadth 11 millim. ( 2.) 
Hab. Mexico (Truqui, in Mus. Brit.). 
One female. Near ZL. discreta, but with the vestiture much coarser, the prothorax 
coarsely, densely punctate (except along the median line), the scutellum squamose, the 
elytral interstices not wider than the striz and rather coarsely uniseriate-punctate 
throughout. Smaller and less elongate than L. desidiosa, the elytral vestiture coarser 
and denser at the sides, the interstices narrower. 
17. Limnobaris leucostigma, sp. n. | 
Elongate, narrow, somewhat flattened above, shining, piceous, the legs fusco-ferruginous; the elytra with a 
small spot at the base of each interstice, and a transverse patch at the middle of the disc towards the 
apex, clothed with rather coarse, oblong, white scales, the sides of the prothorax, under surface, and legs 
more sparsely set with similar scales. Head almost smooth, transversely grooved between the eyes; 
rostrum curved, moderately stout, about as long as the prothorax, finely punctate, the antennew inserted 
at the middle, the antennal club short-ovate. Prothorax as long as broad, narrowed and feebly 
constricted in front, the sides rounded anteriorly and almost parallel behind ; closely, uniformly punctate, 
except along the smooth median line. Scutellum very small, narrow. Elytra oblong-oval, very little 
wider than the prothorax, conjointly rounded at the apex; sharply punctate-striate, the interstices 
broad, flat, very finely uniseriate-punctate, all rugulose at the apex. Beneath closely punctate ; first 
ventral segment and the base of the second excavate down the middle. Prosternum unimpressed, 
flattened between the anterior coxe, which are separated by rather more than their own width. Legs 
rather stout; tibie strongly unguiculate, all somewhat hollowed towards the apex and pilose on their 
inner edge. 
Length 33, breadth 1} millim. (¢.) 
Hab. Muxico, Jalapa (Hége).
