SC@2MIAS.—MENCHERES. 5 
epistoma very feebly trilobed and almost rounded in front, the elytra with scattered 
rows of appressed hairs, the eyes not carinated within, &c; from Emmenastus it may be 
known by the shorter and stouter legs. 
1. Semias minuta. (Tab. L. fig. 5.) 
Oval, convex, black, shining, slightly pubescent. Head coarsely and closely punctured; prothorax transverse, 
convex, rounded at the sides, a little wider behind than in front, widest just before the base, angles 
obtuse but little prominent, base feebly bisinuate, coarsely and closely punctured, indistinctly impressed 
transversely behind just with the basal margin; elytra slightly wider than the thorax at the base, rounded 
at the sides, widest about the middle, convex, with regular rows of coarse punctures distinct to the apex, 
the interstices flat, almost impunctate, with scattered indistinct appressed greyish hairs. Legs and 
antenne red. Beneath reddish brown, shining, with scattered rather coarse punctures. 
Length 3-33 millim. 
Hab. Muxico, Cordova (Sallé). 
Five examples. 
MENCHERES. 
Mentum transverse, angular at the sides, truncate in front, and closely fitting to the side pieces of submentum ; 
mandibles sharply toothed on the upperside, truncate at apex; maxillary palpi stout, apical joint narrowly 
and feebly triangular; labrum not very prominent, clasped by the mandibles; ligula entirely concealed ; 
epistoma a little produced in the middle, broadly rounded in front, the lateral lobes rounded but little 
swollen; prothorax transverse, closely fitting to the elytra, lateral and basal margins a little thickened and 
reflexed; elytra long, with regular rows of punctures and short appressed hairs; antenne thickening a 
little towards the apex, third joint half as long again as the second, fourth to seventh decreasing a little 
in length, eighth to tenth subtriangular, eleventh narrower ovoid; legs moderate; intermediate and pos- 
terior tarsi long, basal joint of latter about equal in length to the fourth joint, all the tarsi beneath clothed 
with short stiff hairs and the last joint feebly sulcate; metasternum long; intercoxal process acuminate 
and pointed in front (elongatus), or narrow, shorter and rounded in front (ncaraguensis); prosternum 
narrow, declivous behind; epipleure distinct, narrowing from the shoulders, obsolete a little before the 
apex; scutellum small, transverse; eyes rounded ; intermediate coxal cavities closed externally; ventral 
segments corneous. 
One species from Guatemala and one from Nicaragua will constitute this genus. 
Allied to Emmenastus, from which it may be known by its more strongly margined 
thorax, trilobed front, the rows of short hairs on the elytra, &c.; also superficially 
resembling certain Blapstinus and allies. Mencheres might be placed in either of the 
groups Thinobatini or Gnathosiini. The head is feebly trilobed in front. 
1. Mencheres nicaraguensis. 
Oblong oval, reddish brown, convex, pubescent, slightly shining, apterous. Head coarsely and not very closely 
punctured ; prothorax rather convex, somewhat coarsely and closely punctured, transverse, rounded at the 
sides, widest about the middle, lateral margins a little thickened and narrowly reflexed, narrowed in front 
to the slightly prominent obtuse front angles, very slightly narrowed behind, hind angles rectangular, base 
strongly bisinuate, closely fitting to the elytra, and the margin a little raised, narrowly reflexed and promi- 
nent in the middle, the disc slightly impressed transversely behind just in front of the basal margin ; 
elytra with regular rows of rounded punctures distinct to the apex, the punctures close together and the 
rows more distinct outwardly [a little indistinct towards the suture], interstices flat with fine scattered 
punctures, and each with a row of short appressed yellowish hairs, long, convex, a little rounded at sides, 
a little wider than the thorax at the base, humeral angles obtuse, base bisinuate. Beneath shining, with
