larva, but is not known to occur in this country. In Euro])e it is

THE TWELVE-SPOTTI^^I) ASPARA(;US BEETLE. 
(Crioceris IJ-punciata Linn.) 
This species did not appear at Cabin John, Md., until the first week 
of May, a Aveek later than the common species, and even then Avas 
found in only small numbers. This may or liiay not have any signifi- 
cance, but it is not irai^robable considering the habits of these beetles 
that the common species is habitually the earlier arrival. 
Tlie end ^^^^^ oviposition. — In previous years nothing was learned of 
the oviposition of this species. Captured beetles refused to lay when 
confined for the purpose, and the eggs could not be found in the field. 
The i)resent year yielded better success. Eggs were not found until 
nearly a month after the first api)earauce of the beetle, and it is possible 
that the beetles wait some time for the development of the berries 
before depositing on them, since the first eggs were observed May 31. 
These were laid on their sides in a vial in which a female had been 
placed. Subsequently eggs were obtained in jars containing fresh 
sprays of asparagus, and still later in the experimental beds connected 
with this office. 
The eggs are deposited singly and by preference upon old plants, 
toward the ends of shoots which lower down bear ripening berries. 
They are always attached along their sides instead of at one end, as is 
the case with (/. asparagl; not infrequently by two sides, so that the eg^ 
lies between two leaves; but more often they are attached along one 
side only. The total number deposited by a single individual is prob- 
ably the same, as is also the number deposited at one time of deposi- 
tion. A female kept over night had deposited 9 eggs, evidently all 
within a short time of each other, judging by their appearance. One
