apex and the terminal point of the keel is an oblique ridge: the su- 
tural portion of the elytra is distinctly indented near the scutellum, 
and less distinctly so at other parts. 'The mentum is coarsely punc- 
tured: the prosternum and mesosternum are coarsely punctured in 
the middle, and the punctures are confluent: the metasternum has 
small and somewhat irregular longitudinal ruge in the middle, and 
similar ruge are observable on the first, second, and anterior half of 
the third abdominal segments. The legs are black, but the tip of 
the femora and base of the tibiz are pitchy. 
Very many specimens of this species were sent to this country by 
Mr. Bridges, and as I have reason to believe they will be distributed 
in most of the public and private entomological collections, I shall 
regard it as a type for comparison in describing some other species 
of the same genus. 
NycTELIA L&VIS, var. RUFIPES. Many specimens of a Nyctelia 
agreeing with the N. levis, but differing in having the legs and an- 
tenne of a pitchy red colour, were contained in Mr. Bridges’s collec- 
tion. Of these red-legged specimens, as well as of those having the 
legs concolorous with the body, there are males and females ; but the 
red-legged specimens are generally rather narrower, and often have 
a slight trace of transverse depressions on the outer side of the elytra ; 
the difference of form and sculpturing, however, is not constantly 
combined with the red colouring of the legs and antenne, and as in 
some other species of Nyctelia and. Epipedonota I have found a similar 
difference in the colouring of the legs, &c., I cannot regard that 
character as specific. 
NYcTELIA TRANSVERSO-sULCATA. Nyct.atra, nitida ; capite antice 
sparsim punctato : elytris vix dupld latioribus quam longis, antice 
potiusquam postice angustioribus, angulis productis, subacutis : 
elytris mediocriter convexis, brevibus, ovatis, apice producto, sulcis 
haud ad medium attingentibus, profundis et levitér undulatis, trans- 
versim insculptis ; segmentis abdominalibus fere levibus. 
Long. corp. 9 lin.; lat. 54. 
This species is smaller than the N. Jevis, and the thorax and 
elytra are less convex. ‘The head has a few scattered punctures in 
front, and numerous very fine punctures on the hinder part, near 
the eyes; the remaining portions are smooth. ~The thorax is im- 
punctate, but little convex above, and has two indistinct fovez on 
each side near the posterior angles, and joining the hinder margin. 
The elytra are ovate and slightly convex ; the apical portion is pro- 
duced, and has the outer margin slightly reflected : the lateral keel 
of the elytra is very prominent, and distinctly crenulated : extending 
inwards from this keel, to about the middle of the elytron, are a series 
of transverse and slightly irregular grooves, about fourteen in num- 
ber, on each elytron; the length of these grooves (the interstices of 
which are convex) varies so, that they all terminate nearly at the 
same distance from the suture. On the space between these trans- 
verse sulci and the suture are two longitudinal striz, which are some- 
what indistinct, and interrupted in parts, excepting on the apical
