Observations on the various Insects 
I found also one full-gtown maggot, and a parasitic fly in a cell 
lined with a shining membrane. The beans with few exceptions 
appeared sound outside ; but on a more searching examination 
pale or horny spots were discoverable on the skin (fig. 24, p), or 
a little space marked merely by a delicate circular line indicated 
what might be expected beneath, as exhibited higher up in the 
same figure. There were occasionally pitchy dots or punctures, 
which possibly might be the spot where an egg had been depo- 
sited, for in some instances the incision entered the farinaceous 
substance of the bean, and in others a small maggot had been 
feeding in his little cell, but from the size and form of the head I do 
not think it was the larva of the Bruchus : rarelj"^ a larger hole 
was visible, which had been eaten by the beetle preparatory to its 
escaping from the cell, immediately on its bursting from its pupa 
shroud (fig. q). On cutting open the beans, some contained 2, 3, 
and even 4 cells (fig. 25) ; in a few were larva? of various sizes 
(fig. r), in which case there was a good deal of farinaceous pow- 
der around them ; others contained the beetle just changed, with 
the elytra not expanded ; but in most of the cavities I found the 
perfect Bruchus (fig. s), with its head downward, and next the 
transparent spot, as shown in fig. 24, p, with the excrement and 
debris left by the maggot at the opposite end. Generally speak- 
ing, the portion where the germ of the seed is situated was left 
untouched, but occasionally the cell did extend to that part. 
The maggots were like that already described — fleshy, wrinkled, 
with a minute, horny, ferruginous head, and their ochreous colour 
might be owing to their being dead (fig. 26, fig. 25, r, the natural 
size). The pupa? were, I believe, all dead, and presented various 
stages of development, some showing but faint traces of the future 
beetle, and others having every member perfectly formed (fig. 27). 
This beetle, which is a different species to any I have seen in the 
other samples, has been named by Schonherr* — 
8. Bruchus flavimanus. It is similar in size to B. Pisi, but formed 
more like B. granarius : it is black ; the head and thorax are clothed 
with short orange-coloured hairs, having a distinct cream-coloured tri- 
angular spot before tlie scutellum, which is of the same colour; there 
are two minute wliite dots on tlie disc; the lateral teeth arc acute and 
pale : the wing- cases are of an ashy-white, with a few brown spots ; the 
suture is ochreous-white, and there are four white dots un the disc: the 
exposed apical segment of the abdomen is ochreous-white, witli two oval 
olive-brown spots near the apex : on the under side, which is silky 
slate-colour, is a pale line under the shoulder of the elytra, and a row of 
white abdominal dots, as in B. yrunariiis : the anterior pair of legs and 
4 basal joints of the antennae are bright ferruginous, the apical joint of 
the former brown ; the other legs are clothed with fine ochreous hairs,
