HETEROMERA. 481 
The numerous specimens received from Mr, Gaumer connect Z. rotundicollis and 
L. intermedius with ZL. belti. The thorax is more rounded at the sides in some 
examples (as in #. rotundicollis and £. belti), and the punctuation is variable, it 
being finer and sparser on the disc (Z. belti and F. intermedius) or almost uniform 
(£. rotundicollis). 
Emmenastus parallelus (p. 12). 
To the locality Mexico, add:—Matamoros Izucar (Flohr, Hoge), Cuautla (Flohr), 
Atlixco, Cuernavaca (Hége). 
Numerous additional examples have been received of this species. 
10 (a). Emmenastus mexicanus. 
Elongate-ovate, narrow, subparallel, black, opaque. Head thickly, rather coarsely punctate, the eyes not 
‘prominent; antenne slender, moderately long; prothorax convex, strongly transverse, subparallel 
behind, narrowing anteriorly, the anterior angles sharp, the hind angles subrectangular, the base feebly 
bisinuate and with a very shallow but distinct fovea on either side laterally, the surface rather coarsely, 
confluently punctured towards the sides, sparsely and finely so on the middle of the disc, the disc with 
a smooth central line and a transverse depression before the base, a narrow space between the basal foveve 
shining, more sparsely punctate; elytra the width of, and about four times as long as, the prothorax, 
subparallel to beyond the middle, with rows of fine, approximate, rather deep punctures, the interstices 
flat, each with an irregular row of minute punctures; beneath very sparsely punctate; tarsi clothed with 
coarse yellowish hairs beneath: body winged. 
Length 7-77 millim. 
Hab. Mexico, near the city (Hége). 
Two examples. Allied to EZ. parallelus, but with the thorax more coarsely, more 
sparsely punctate, and very shallowly but distinctly foveate at the base towards the 
sides, the space between the fovee shining and almost smooth; the elytra with the — 
serial punctures coarser and more deeply impressed. 
Emmenastus tenebrosus (p. 12). 
To the Mexican locality given, add :—Aguas Calientes city, Mexico city (Hoge). 
The wings in this species are abbreviated. 
12 (a). Emmenastus subapterus. 
Elongate-ovate, rather broad, slightly shining, black or pitchy-brown. Head finely, somewhat thickly punctate, 
the eyes not prominent; antennz slender, moderately long; prothorax strongly transverse, moderately 
rounded at the sides, narrowing from about the basal third, the anterior angles rather sharp, the hind 
angles subrectangular, the base distinctly bisinuate and grooved within the margin on either side of the 
middle, the surface finely, thickly punctate, the punctures towards the sides partly confluent; elytra 
moderately long, with rows of very distinct, fine, approximate punctures, the interstices flat, very sparsely, 
minutely punctate; beneath obscure ferruginous, somewhat thickly punctured ; tarsi clothed with coarse 
hairs beneath ; wings very small, rudimentary. 
Length 7-73 millim.
