is, in the southern part of the State, another ally of the June 

 beetles known as the fig eater, A 1 1 o r h i n a n i t i d a Linn., 

 peculiar because of its dull greenish color, the wing covers being 

 usually margined with yellowish brown, and on account of the 

 peculiar locomotion of the larvae : these latter turn on their backs 

 and travel rapidly by a series of undulating movements which are 

 made very effective by the short, stout dorsal spines. 



New York species. The following species of Lachnosterna 

 have been recorded from New York State : L. g 1 a b e r r i m a 

 Blanch.. L. gracilis Burm., L. gibbosa Burm., L. 

 c r a s s i s s i m a Blanch., L. m i c a n s Knoch. L. f u s c a Froh., 

 L. a r c u a t a Sm., L. d u b i a Sm., L. g r a n d i s Sm., L. 

 marginal is Lee, L. fraterna Harr., L. nova Sm., 

 L. knoch ii Gyll., L. rugosa Mels., L. hirsuta Knoch, 

 L. b a 1 i a Say, L. n i t i d a Horn, L. h i r t i c u 1 a Knoch, L. 

 i 1 i c i s Knoch, L. crenulata Froh., and L. t r i s t i s Fabr. 

 That the above list is not exhaustive is evidenced by the thirty-one 

 species recorded from New Jersey, presumably as a result of 

 special collecting which has not been possible in this State. 



White grubs. 

 The term white 

 grub is more than 

 generic, since it is 

 applied indiscrimi- 

 nately to a large 

 number of Coleop- 

 terous larvae found 

 under grass sod 

 and in decaying or- 

 ganic matter. These 

 larvae resemble 

 each other in a een- ^^^- ^ White grubs in earthen cells (original) 



eral way and it is not surprising that they should be confused in the 

 popular mind. The white grubs of the entomologist comprise an ag- 

 gregation of forms normally living on grass roots and referable, as 

 shown by rearing the adults, to several genera. Unfortunately, our 

 knowledge of the immature stages is such that beyond a few general 

 characteristics it is impossible to identify the various species of 

 Lachnosterna as larvae. Large, stout, white, curled grubs, half an 

 inch to an inch in length, with brown heads, and living on grass roots 

 or those of closely allied plants in this latitude, are mostly referable
