TARPELA. 301 
and finer, longer, and more widely separated towards the apex, the interstices flat on the disc, a little 
convex towards the sides, and very distinctly punctured; beneath more shining, dark reddish-brown, the 
flanks of the prothorax and the metasternum at the sides with coarse, scattered impressions, the ventral 
surface sparingly and finely punctured and longitudinally wrinkled, the last ventral segment in the male 
hairy at the apex; prosternum declivous, the apex with a very small raised point ; mesosternum declivous, 
very feebly excavate; legs rather long, moderately coarsely but not very closely punctured, the femora a 
little smoother; epipleure abruptly narrowing at the last ventral suture. 
Length 10 millim.; breadth 43 millim. (<¢.) 
Hab. Mexico (Sallé, ex coll. Sturm). 
One example. Resembles 7’. atra, from which it is separated by the shorter head, 
stouter antenne, broader and more quadrate thorax, prominent humeri (the elytra not 
truncate at the base as in that species), the impressions on the elytra much coarser and 
deeper towards the sides, the legs and under surface very much smoother, the flanks of 
the thorax coarsely but not closely punctured (not shallowly and confluently so), &c. ; 
from T. azteca it may be known by the less prominent anterior angles of the thorax, less 
prominent humeri, flatter interstices, more coarsely punctured elytra, &c. 
Helops impolitus, Lec., from Texas, is apparently an ally of this. species. 
Y 25. Tarpela fallax. (Tab. XIII. fig. 8, 2.) 
Oblong ovate, dark bronze, rather dull. Head short, very shallowly transversely impressed in front, very 
closely, coarsely, and equally punctured, the punctures here and there longitudinally confluent, the 
epistoma short; antenne in the male reaching nearly to the middle of the elytra, much shorter in the 
female, joints 8-10 widening a little outwardly, the apical joint in the male slightly longer than the tenth : 
prothorax short, transverse, rather convex, somewhat strongly margined, the margins narrowly grooved 
within, the sides narrowing and rounded anteriorly, and almost straight or feebly narrowing and sinuate 
behind, the anterior angles narrowly rounded though a little prominent, the apex shallowly emarginate, the 
hind angles subrectangular, the base feebly bisinuate, the basal fovee shallow, the disc usually semicircularly 
impressed before the base and sometimes with a smooth central line, the surface rather coarsely, closely, 
and subequally punctured; elytra moderately long, wider than the prothorax, subparallel, widest behind the 
middle in the female, somewhat flattened on the disc, the humeri a little prominent in front, rather deeply 
striate, the strie with moderately fine not very closely placed impressions, the interstices almost flat on 
the disc, very feebly convex outwardly, and minutely and sparingly punctured ; tibie roughly and closely 
punctured, the femora very much smoother ; beneath darker bronze, sparingly and not very finely punctured, 
the ventral surface also strongly longitudinally wrinkled, the flanks of the prothorax rather finely strigose, 
the ventral segments 1-3 in the male slightly flattened and finely and closely punctured and pubescent 
along the middle ; prosternum declivous, the apex sometimes transversely raised ; mesosternum very feebly 
concave; epipleurse almost ending at the last ventral suture. 
Length 63-114 millim.; breadth 3-5; millim. (¢ 9.) 
Hab. Mexico, Jalapa, Tampico (Hoge). 
Found in plenty by Herr Hoge at Jalapa. This species is not very nearly allied to 
any other described here; it will be identified by its comparatively short head, short 
and anteriorly narrowed thorax (the anterior angles of which are not prominent), 
punctate-striate elytra, and other characters mentioned above.
