HELOPS 317 
coarsely punctured, the punctures rather more scattered on the disc ; scutellum very broad, transverse ; 
elytra broad, a little flattened on the disc, the width of the widest part of the prothorax at the base, the 
sides slightly rounded, the base distinctly grooved on each side for the reception of the hind angles of the 
prothorax, the humeri swollen and directed a little outwards, with rows of very coarse elongate distantly 
placed impressions, the impressions nearly equal in size throughout, the interstices almost flat and shallowly 
though very distinctly punctured ; beneath (including the flanks of the prothorax) very coarsely punctured ; 
prosternum declivous, the apex with a small raised point in the middle; legs short and very stout, the 
femora and tibie very coarsely and closely punctured. 
Length 12 millim.; breadth 53 millim. 
Hab. Mexico (Sallé, ex coll. Sturm). 
I have adopted the MS. name by which this insect is labelled in the Sallé collection. 
H. punctato-striatus may be known by its broad, greatly developed, and closely and 
coarsely punctured thorax, broad scutellum, prominent humeri, the rows of equal-sized 
very coarse elongate impressions on the elytra, the short, stout, coarsely punctured 
legs, &c.; it cannot be compared with any other species here recorded. The single 
example before me is greatly mutilated, and without abdomen and antenne. 
9. Helops pueblensis. 
Oblong ovate, very convex, dark bronze, moderately shining. Head very closely and rather coarsely punctured, 
the punctures more or less longitudinal in form and here and there obliquely or longitudinally confluent, 
the eyes only feebly convex ; antennx (female) reaching to about the first fourth of the elytra, rather 
slender; prothorax transverse, very feebly margined, the sides slightly rounded, widest in the middle, and 
about equally narrowed towards the base and apex, the angles obtuse, the apex (if viewed from above) 
and base almost straight, the base very obsoletely margined, the basal fovese shallow and indistinct, the 
surface very closely and somewhat coarsely punctured, the punctures here and there longitudinally 
confluent, and with a narrow irregular smooth longitudinal space on the middle of the disc; scutellum 
large, very strongly transverse; elytra a little wider than the prothorax at the base, moderately long, 
slightly rounded at the sides, the base sinuate on each side and grooved within for the reception of the hind 
angles of the prothorax, the humeri rounded but prominent in front, with rows of moderately coarse elongate 
closely placed impressions, the impressions here and there confluent, the interstices flat and sparingly but 
very distinctly punctured, the third a little raised at the apex; beneath sparingly but rather coarsely 
punctured, the ventral surface also strongly longitudinally wrinkled, the flanks of the prothorax closely 
punctured, the punctures elongate in form and here and there confluent ; prosternum declivous. 
Length 94 millim. ; breadth 43 millim. (@.) 
Hab. Mextco, Matamoros Izucar in Puebla (Hége). 
One example. From H. coxalis this species is separated by the thorax being less 
rounded at the sides, less transverse, and very feebly margined, the margins not grooved 
within; the elytra longer, with rows of coarse elongate impressions, the interstices 
flat and distinctly punctured, &c. From the North-American H. ereus by the very 
different sculpture of the flanks of the thorax, and the obtuse (not rectangular) hind 
angles; the coarser elytral impressions, &c. 
10. Helops coxalis. (Tab. XIII. fig. 25, ¢ .) 
Oblong ovate, convex, prownish-bronze, with a slight golden tint, moderately shining. Head shallowly trans- 
versely impressed in front, closely and coarsely punctured, the punctures obityuely or longitudinally
