342 HETEROMERA. 
number of species cannot be less than 400, a very large proportion of which inhabit 
Tropical South America. 
We have now to record 67 from Central America, the majority of the new species 
being, as might be expected, from the southern part of our region. 
All the species here referred to it have the third joint of the antenne longer than 
the fourth, or the third and fourth joints subequal. The first joint of the posterior 
tarsi varies very much. in length, the eyes are sometimes very large and approximate, 
sometimes quite small and widely separated, and generally largest in the male, and the 
usually hidden and more or less corneous sixth ventral segment is sometimes visible, in 
the different species. The males often have the anterior tibie more curved, or slightly 
sinuate, and more evidently pilose within than in. the female, and the fifth ventral 
segment impressed (sometimes in the female also) in the middle behind; in some 
species (e. g. S. maculicolle) the metasternum is somewhat thickly clothed with short 
decumbent hair (as in certain Cuphotes) in this sex. | 
A. Form broad, oblong ovate, comparatively short (resembling Poecilesthus) ; eyes small ; 
upper surface comparatively very smooth and shining. LElytra regularly convex, 
very finely and lightly striate-punctate, with the interstices quite flat; testa- 
ceous or red, sometimes maculated. 
* Prothorax with the sides feebly margined towards the base. 
1. Strongylium maculicolle. (Tab. XIV. fig. 16, 3.) 
Oblong ovate, comparatively broad, moderately convex, reddish-testaceous, shining. Head sparingly but deeply 
and somewhat coarsely, the epistoma much more closely, punctured ; the intraocular space with a smooth 
longitudinal, slightly impressed, space down the middle; the eyes small and widely separated; the oral 
organs, the epistoma in the middle, the sides behind the eyes, and, rarely, the extreme base piceous or 
black; antenne moderately long, very slightly widening outwardly, joints 3 and 4 long, subequal, 5-10 
gradually decreasing in length, much longer than broad, the apical joint ovate, and rather longer than the 
tenth, black; prothorax strongly transverse, moderately convex, the base feebly bisinuate, the apex very 
slightly emarginate on each side behind the eyes, the sides very feebly but distinctly margined at the 
. base, and obsoletely so at the apex, narrowing from the base, and slightly sinuous about the middle, the 
anterior angles rounded and rather prominent, the hind angles subacute, the basal fovez deep, the disc 
impressed in the middle at the base, and often obsoletely canaliculate in front, the surface finely and 
sparingly (but deeply) punctured, with a more or less broad black stripe (usually narrowing towards 
the middle, and leaving a large triangular patch in front) on the disc, this stripe connected along the base 
with a large triangular black patch occupying the hind angles; scutellum large, scutiform, sparingly 
punctured, piceous or black; elytra comparatively broad and short, widest a little behind the middle, 
subparallel in their basal half, finely striate-punctate, the interstices perfectly flat and closely and very 
distinctly punctured, the surface stramineous in colour, and of a much lighter tint than the prothorax, 
each with three rather large spots placed transversely before, and three other smaller spots (sometimes 
confluent, sometimes very small) placed transversely behind, the middle, fuscous or black; beneath reddish- 
testaceous, the flanks of the prothorax and the sides of the meso- and of the metasternum and side-pieces 
more or less stained with piceous or black, moderately closely punctured, sparingly pubescent; the meta- 
sternum in the middle, and the inner side of the curved anterior tibise from the middle to the apex, 
somewhat thickly clothed with hair in the male; legs rather long, the first joint of the posterior tarsi 
very long, black or piceous, the basal half of the femora reddish-testaceous.
