482 SUPPLEMENT. 
Hab. Mexico, Ventanas in Durango (Hége), Canelas in Durango (Flohr). 
Three examples. This species is nearest allied to #. tenebrosus, but has still more 
rudimentary wings; it is also broader and has the elytral interstices very sparsely, 
minutely punctate, the serial punctures much more distinct. In the single specimen 
from Canelas the thorax has an oblique basal fovea on one side and not on the other. 
From F. picipes &c. the present species may be easily known by the distinctly bisinuate 
base of the thorax. 
Emmenastus alatus (p. 13). 
Emmenastus salvini, huj. op. p. 18. 
16 (a). Emmenastus seriatus. 
Oblong-ovate, brownish-black, opaque, the elytra slightly shining. Head rather sparsely, finely punctate, more 
coarsely so between the eyes, the latter not prominent; antennz slender; prothorax convex, transverse, 
moderately rounded at the sides and gradually narrowing almost from the base, the base strongly bisinuate 
and grooved within the margin on either side of the middle, the anterior angles rather sharp, the hind 
angles subrectangular, the surface finely, moderately closely punctured, the punctures finer and more 
scattered on the disc; elytra the width of the prothorax at the base, subparallel in their basal half, 
moderately long, with series of rather coarse, deep, approximate punctures, the interstices flat, with 
serially arranged fine punctures, which become coarser towards the suture; beneath sparsely punctate ; 
tarsi with spiny hairs beneath: body winged. 
Length 6-63 millim. 
Hab. Mexico, Tehuantepec (Hoge). 
Three examples. Allied to #. guatemalensis, but larger and less parallel, with the 
interstitial punctuation of the elytra coarser and closer towards the suture. It differs 
from £. alatus in having the basal margin of the thorax grooved within on either side 
of the middle, without trace of foveer. 
Emmenastus confusus (p. 15). 
‘To the localities given, add :—Mexico, Tapachula in Chiapas (Hoge). 
Found in plenty by Herr Hoge. 
19 (a). Emmenastus constrictus. 
Elongate, narrow, opaque, pitchy-red. Head densely, rather coarsely punctate, the epistoma subangularly 
produced in the middle and separated from the lateral portions by a distinct emargination ; the eyes 
prominent; the mandibles toothed on the upperside at some distance before the apex; antenne slender, 
moderately long; prothorax convex, transverse, narrowed behind, only a little wider at the base than at 
the apex, widest at the middle, the sides strongly rounded, the anterior angles acute, the hind angles 
subrectangular, the base bisinuate and rather broadly and deeply grooved within, the groove terminating 
laterally in a very shallow oblique depression, the surface closely and rather coarsely punctate, the 
punctures a little finer and more scattered on the disc; elytra elongate-oval, slightly narrowed at the 
base, with rows of very shallow, fine, approximate, muricate punctures, which become almost obsolete on 
the disc towards the apex, the interstices flat, finely alutaceous, very shallowly, sparsely, minutely
