formations, describes after Le Keux the history of the HeHica nemorum, 

 a European species scarcely separable from this, supposing the two 

 to have the same habits ; but the accurate observations of Dr. Shimer 

 have shown this to be a mistake, as the larvae of the European spe- 

 cies reside in the leaves of vegetables; those of our species live under 

 ground, feeding on the roots of -plants in the same manner as the 

 striped cucumber beetle, (Diabrotica vittata.) 



The larva is a minute, slender grub, with six tiny feet on the three 

 anterior segments and an anal pro-leg ; white with a faint, dark me- 

 dial line along the anterior part of the body ; a horny, light-brown 

 head, and a brown spot on the posterior extremity. This state lasts 

 about seventeen days, when it changes into a naked white pupa in 

 a little earthen cocoon near its feeding place, in which it remains but 

 a short time. From the observations made, Dr. Shimer is of the opin- 

 ion that they live exclusively on the roots and underground stems of 

 crucifreous plants. 



Remedies.— Powdered lime, which has frequently been recom- 

 mended, appears on trial to be but a partial remedy ; if sprinkled on 

 the plants when the dew is on them it appears to impede the move- 

 ments of the insects and thus assists in driving them away. A so- 

 lution of lime is considered in England one of the best remedies for 

 its congenor, the turnip flea-beetle. It is probable there are various 

 applications of this nature which will prove beneficial, and no doubt 

 Paris green would be almost if not quite a specific ; but I cannot re- 

 commend its use upon such vegetables as cabbage, mustard, etc., where 

 the part above ground is to be used, even though it be applied when 

 the plants are young, although with proper care there is probably no 

 danger in such cases. 



Spec. char. Imago.— Head small and deeply sunk into the thorax; 

 antenna; inserted near to each other in the middle of the face, about 

 half the length of the body, and slightly enlarged toward the tips, 

 composed of eleven joints. Thorax transverse, that is broader than 

 long ; sides rounded ; about two-thirds the width of the elytra or 

 wing-cases. The wing-cases when closed are oval in shape, verv 

 slightly narrowing posteriorly and rounded at the tip, and not striated. 

 It is of a shining .black color, each wing-case marked with a rather 

 broad, yellow stripe which runs from the shoulder nearly to the tip ; 

 slightly and regularly curved outward near each end and inward in 

 the middle portion, occupying the middle third of each case, but 

 slightly narrowed and interrupted near the middle portion. Legs 

 black, with the knees and feet pale.
