the rostrum slightly thickened at apex, and the thorax more closely and 
granulately sculptured; in the only specimen I have seen, the elytra are 
more pubescent, the pubescence being rather obscure, but plainly 
chequered. L. 43-5 mm. 
Amongst moss and decaying vegetable matter; Mr. Walton (Annals and Mag. of 
Natural History, 1844, 111) says that the only specimen he had seen was found 
amongst moss and decayed vegetable matter from a wood at some distance from 
Carlisle, in December, by T. C. Heysham, Esq., who presented it to him; this speci- 
men is probably the one in Dr. Power’s collection as it has Mr. Heysham’s name 
behind the card on which it is mounted ; at first sight it looks distinct from the type 
form, but the latter is variable in size, pubescence, &c., and Mr. Crotch was evidently 
right in regarding it as only an extreme form of the ty pe. 
PACHYTYCHIUS, Jekel, 
This genus contains a considerable number of species which are dis- 
tributed over a great part of the old world; more than twenty occur in 
Kurope ; they have long been regarded as belonging to T'ychius, but may 
easily be distinguished by the structure of the ventral segments (of 
which the second does not at the sides attain the fourth), and the fact 
that the tarsal claws are not appendiculate ; the single British species 
used to be regarded as one of our rarest insects, but has recently been 
found in considerable numbers near Gosport by Mr. Monereaff, 
P. hematocephalus, Gyl]l Rather short and broad, pitchy red or 
ferruginous, sometimes pitchy black ; head, antenne and rostrum red, 
the latter moderately long, stout, strongly curved, and finely striated, 
shining; thorax transverse, broad, with the sides strongly dilated and 
rounded and narrowed at base and apex, punctuation close and fine but 
distinet, pubescence scanty except at sides where there is a more or less 
distinct whitish curved spot; scutelium thickly covered with greyish- 
white scales ; elytra at base not broader than middle of thorax, rather 
short, subparallel, narrowed at apex, with tessellated greyish scales, 
which are often dark along suture, underside with whitish or greyish. 
scales ; striz distinct, but not strongly punctured, interstices rugose 
legs stout, ferruginous, more or less squamose, anterior and intermediate 
femora simple, posterior femora strongly toothed. L. 3-4 mm. 
On Lotus corniculatus ; extremely local ; Portsmouth district (Moncreaff) ; Mr. 
Moncreaff says that it is abundant in June at the roots of grass near Gosport, and 
that it feeds on the seeds of the birdsfoot trefoil; the larve, according to Perris, 
live in the pods of this plant. 
GRYPIDIUS, Stephens. 
This genus only comprises four species which are peculiar to the 
colder portions of the Northern Hemisphere ; they are moderate-sized 
insects with the rostrum long and curved, the femora simple and the 
tibie slender ; the antenne are rather long and the eyes moderately
