slightly compressed joints ; the first jomt is rather stouter than 
the rest, and perhaps a trifle longer ; the second and third jomts 
are short, but the third rather exceeds the second in length ; the 
remaining joints are very nearly equal. There is an agreement 
also in the form of the thorax, the length of which is about equal 
to the breadth behind ; the fore-part contracted, and of the same 
width as the head ; the posterior angles produced posteriorly, and 
acute; the antennal groove beneath, short, and confined to the 
anterior part of the preesternum, which has its point bent inwards. 
The mesosternum has a small hollow with raised margins in front. 
The metasternum is produced posteriorly so as partially to cover 
the trochanter. In all these characters the Galapagos insect ap- 
pears to me to agree with the type of the genus Physorhinus ; but, 
on the other hand, it differs in having the head rather shorter, 
presenting when viewed from above very nearly a semicircular 
outline, but slightly inclining to a conical form,—whilst Germar 
says of the genus Physorhinus, the head is longer than broad ; and 
it differs also in having the terminal joint of the tarsus (as it 
would appear from the figure) rather longer, so that although 
the basal joint is long, it is not quite equal to the other four taken 
together, as it is said to be in Physorhinus. The claws are slender 
and simple, and the tarsi very hairy.

rina transversa tri-emarginata obsito; ante oculos lobis subtrigonis 
productis ; clypeo producto, antice recurvo, constricto, subemar-

Head with large irregular scattered punctures ; these most nu- 
merous, and confluent, on the fore-part ; the vertex flat and smooth; 
the sides produced into an obtuse angle immediately in front of 
the eyes ; the fore-part with a distinctly elevated ridge, which is 
most prominent in the middle, and has a deep notch ; it becomes 
gradually less prominent towards the sides, but is there produced
