middle of the breast, are deep blue-black ; the thorax, wing- 
covers, and abdomen are dull red ; the wing-covers, taken 
together, are nearly square, and are punctured in rows. 
This beetle is found on the leaves of oak-trees in June and 
July. 
The two-spotted Attelabus, Attelabus bipustulatus of Fabri- 
cius, (Plate II. Fig. 6,) is also found on oak-leaves during the 
same season as the preceding. It is of a deep blue-black 
color, with a square dull red spot on the shoulders ot each 
wing-cover. It measures rather more than one eighth of an 
inch in length. 
Two or three beetles of this family are very hurtful to the 
vine, in Europe, by nibbling the midrib of the leaves, so that 
the latter may he rolled up to form a retreat for their young. 
They also puncture the buds and the tender fruit of this and 
of other plants. In consequence of the damage caused by 
them and hy their larvae, whole vineyards are sometimes 
stripped of their leaves, and fruit-trees are despoiled of their 
foliage and fruits. These insects belong to the genus Ilyn- 
chites, a name given to them in allusion to their snouts. I 
have not seen any of them on vines or fruit-trees in this 
country. The largest one found here is the Ryncliites bicolor 
of Fabricius, or two-colored Ryncliites. This insect is met 
with in June, July, and August, on cultivated and wild 
rose-bushes, sometimes in. considerable numbers. That they 
injure these plants is highly probable, but the nature and 
extent of the injury is not certainly known. The whole 
of the upper side of this beetle is red, except the rather 
long and slender snout, which, together with the antenna;, 
legs, and under-side of the body, is black ; it is thickly 
covered with small punctures, and is slightly downy, and 
there arc rows of larger punctures on the wing-covers. It 
measures one fifth of an inch from the eyes to the tip of 
the abdomen. 
The grabs of many kinds of Apion destroy the seeds of 
plants. In Europe they do much mischief to clover in this
