diate forms ; but in its elytra being more produced (or less 
obtusely-rounded) behind, in its shoulders being rather 
suddenly and acutely porrected, and in the front tibia3 of 
its type being armed at their inner angle with a compressed 
bifid spur, there is a singularity about it which is essen- 
tially its own. The two species of Tomolips Avhich are 
now before me were taken in Mexico, and are from the 
collection of Mr. Fry. 
118. Dendroctonomorphus {nov. gen.). — It is for a 
Hylastes-, or Dendroctoniis-\\kQ Cossonid from Ceylon, 
which (together with an allied species from Malabar, 
and a rather less typical one from Mexico) has been com- 
municated by Mr. Fry, that I have been compelled to 
establish the present genus. In its structural peculiarities 
it is somewhat intermediate between Brachytemnus and 
Stenoscelis, — agreeing with the former in its conspicuous 
(though less largely developed) scutellum, comparatively 
elongate, almost unconstricted prothorax, the general 
character of its sculpture (which however is not quite so 
coarse), and in its perfectly simple third tarsal joint; but 
with the latter in its asperated elytra, greatly lengthened 
feet, more widely separated eyes, and less glabrous an- 
tennae. In its thickened head, short, triangular rostrum, 
sunken eyes, and cylindrical body, it is in accordance with 
the whole of these sub-IIylastideous forms. 
119. Brachytemnus {nov. gen.). — It is in order to 
receive the European Rhyncolus porcatus, Miill., and my 
nearly-allied R.jjinipotens from the Canarian archipelago,* 
that I have proposed the pi'csent genus ; and it seems mar- 
vellous to me now how those curious insects could ever 
have been included amongst the Rhyncoli — from which 
they appear to differ in nearly every detail of then' 
* My B.jnnipofens (= crassirostris, olim), which I captured in an old 
fir-tree in the island of Grand Canary, is most closely allied to the B. por- 
catus, MiilL, of Southern Europe. Its rostrum and prothorax however (the 
former of which is free from an anterior channel, whilst the latter is less 
sinuated on either side behind the middle) are just appreciably less coarsely 
and more sparingly punctured ; its elytra (which have the shoulders less 
porrect) are a trifle more parallel, there being apparently no tendency to 
be even obsoletely widened posteriorly, and have their apical region less 
obtusely- desilient (or suddenly bent-downwards) ; and the club of its an- 
tennae is rather more truncated in front. The underside also is somewhat 
less grossly punctured, and the first abdominal segment, which is convexer, 
is likewise a little more remotely so.
