the typical Mexican examples, and they seem to be also decidedly more cylindrical in 
form; but in every other respect there is no difference. 
2. Parmenonta ovatula. 
Minus elongata, oblongo-ovata, ochraceo-fusca; elytris lateribus rotundatis, apice utrinque breviter sinuatis, 
, angulo suturali acuto, vix seriatim punctulatis, postice fortiter convexis, macula transversa ochracea ; 
scutello latissimo, angulis rotundatis; pedibus brevibus, precipue tibiis gradatim dilatatis, apice intus 
haud dentatis.

Hab. Guatemata, Zapote (Champion). 
Shorter; the elytra, especially, relatively shorter and more ovate than in P. valida. 
The head and thorax coarsely punctured; the elytra punctured with less regularity 
than in P. valida, the punctures being larger and smaller, as in that species, but 
without much tendency to range in lines. At the base the elytra are scarce perceptibly 
wider than the base of the elytra; but the shoulders are rather distinct, and the sides 
are gradually rounded outwards to two thirds the length, and then more rapidly 
rounded to the sutural apex, near which the margin is slightly sinuated; the pale 
spot lies transversely across the disk at two thirds the length; and there is another, less 
distinct, similar pale spot near each shoulder. ‘The tibie are shorter, and more 
triangular in shape than in P. valida. The mesosternum is plane and not at all pro- 
minent ; the middle cotyloid cavities are distinctly open; and the mesothoracic epimera 
reach to the opening. 
3, Parmenonta minor. 
P. ovatule quoad formam similis, at angustior elytrisque minus late rotundatis, obscurius nigro-fusco 
pubescens, grossius punctata; thoracis lateribus et macula minore elytrorum pone medium obscure 
ochraceis: fusco-subeeneo-nigra; thorace elongato, cylindrico; elytris paullulum rotundato-dilatatis apice 
juxta suturam triangulariter emarginatis; tibiis gradatim dilatatis, intermediis extus ante apicem 
distincte sinuatis. 
Long. 33-33 lin. 
Hab. Mexico, Jalapa (Hoge). 
4, Parmenonta albisetosa. 
P. ovatule affinis, sed minor, elytris relative longioribus, mox a basi paullulum dilatato- rotundatis, longe 
ante apicem gradatim angustatis: subsneo-fusca, fusco-pubescens, punctata ; elytris (precipue postice) 
setarum albarum fasciculis ornatis, apice singulatim rotundatis; tibiis vix dilatatis, intermediis parum 
extus sinuatis. 
Long. 24-33 lin. 
Hab. Guatemaa, Duefias, 4950 feet (Salvin), Duefias, Capetillo (Champion). 
Closely allied to P. minor and P. ovatula, but distinguished in both sexes by the 
form of the elytra, which in P. aldisetosa are dilated (very slightly) immediately from 
the base, and commence again to taper immediately after the middle, whilst in the
