middle of the breast, are deep blue-black ; the thorax, wing- 
covers, and abdomen are dull red ; the Aving-covers, taken 
together, are nearly square, and are punctured in rows. 
This beetle is fomid on the leaves of oak-trees in June and 
July. 
The two-spotted Attelabus, Attslahus bipustulatiis of Fabri- 
* cius, (Plate IL Fig. 6,) is also found on oak-leaves during the 
same season as the preceding. It is of a deep blue-black 
color, Avith a square dull red spot on the shoulders of each 
Aving-coA^er. It measures rather more than one eighth of an 
inch in length. 
Tavo or three beetles of this familv are A^ery hurtful to the 
•, vine, in Europe, by nibbling the midrib of the leaA'es, so that 
the latter may be 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 by their larA'ae, whole Auneyards are sometimes 
stripped of their leaA^es, and fruit-trees are despoiled of their 
foliage and fr’uits. These insects belong to the genus Ryn- 
chites^ a name giA^en to them in allusion to their snouts. I 
haA’e not seen any of them on A'ines or fruit-trees in this 
country. The largest one found here is the Ryncliites bicolor 
of Fabricius, or tAvo-colored RAUichites. This insect is met 
Avith in June, July, and August, on cultiAated and Avild 
rose-bushes, sometimes in considerable numbers. That thev

injure these plants is highly probable, but the nature and 
extent of the injury is not certainly knoAA’n. The Avhole 
of the upper side of this beetle is red, except the rather 
long and slender snout, Avhich, together AA’ith the antennae, 
legs, and under-side of the body, is black ; it is thickly 
covered Avith small punctures, and is slightly doAvny, and 
there are roAvs of larger punctures on the Aving-coA^ers. It 
measures one fifth of an inch from the eyes to the tip of 
the abdomen.

The grubs of many kinds of Apion destroy the seeds of 
plants. In Europe they do much mischief to clover in this
