24, Emmenastus rugicollis. 
Apterous, oblong ovate, convex, black, rather dull. Head closely and coarsely punctured, longitudinally 
rugulose; prothorax broad, transversely convex, rounded at the sides, widest a little before the base, very 
slightly narrowed behind, narrowed in front, anterior and posterior angles obtuse and not prominent, very 
closely regularly and somewhat coarsely punctured, the punctures longitudinally confluent, a central 
shallow impression behind near the base, the base almost straight; elytra about the width of the thorax, 
convex, closely and rather coarsely punctured, with indistinct rows of coarser punctures not reaching the 
apex, and distinct only at the sides, obsolete towards the suture; legs and antenne reddish brown. 
Length 6 millim. 
Hab. Mextco, San Luis Potosi (Dr. Palmer).

25. Emmenastus pulvinatus. 
Apterous, oblong ovate, convex, dull reddish brown or black, the upper surface covered with scattered fine

coarsely and closely punctured; prothorax transverse, convex, rather strongly rounded at the sides, 
widest a little before the base, narrowed in front, a little narrowed behind, the angles obtuse, closely 
evenly and rather finely punctured, the punctures a little confluent at the sides, base nearly straight ; 
elytra about as wide as the thorax, convex, rather short, somewhat rounded at the sides, with indistinct 
rows of fine punctures obsolete towards the suture and scarcely reaching the apex, the interstices closely 
and finely punctured; legs and antenne red. Beneath reddish brown, shining, coarsely punctured ; 
intercoxal process rounded in front. 
Length 6-6} millim. 
Hab. Mexico, Oaxaca (Sallé). 
Three examples. Shorter than E. picipes, the thorax comparatively broader, the 
strie of the elytra finer and obsolete towards the suture. 
26. Emmenastus picipes. 
Apterous, oblong ovate, very convex, dark reddish brown or black, shining. Head coarsely and closely punc- 
tured; prothorax transverse, very convex, rounded at the sides, widest before the base, a little narrowed 
behind to the obtuse hind angles, narrowed in front, anterior angles but little prominent and obtuse, rather 
coarsely closely and regularly punctured, the punctures a little confluent at the sides, a small rounded 
impression near the base in front of the scutellum; elytra convex, a little wider than the thorax at the 
base, rounded at the sides, with distinct regular rows of coarsish punctures distinct to the apex, the rows 
of punctures scarcely coarser outwardly, and equally distinct towards the suture, the interstices finely and 
rather closely punctured; legs and antenne reddish brown. Beneath shining, rather coarsely punctured ; 
intercoxal process slightly rounded in front. 
Length 7 millim.
