THE CANADIAN ENTOMOLOGIST. 



ever, seen in collections examples entirely ochreous. The ^ beak varies 

 in length from one and one-quarter to about twice that of the body. The 

 character distinguishing it from all the other species is that the first joint 

 of the funicle of the antenna is shorter than the second, 



B. rectus Say. — This, like the preceding, was bred from chestnuts 

 only. The first example appeared June 28, and others followed very 

 sparingly, and till date (Oct. ist) ninety-five examples have been taken. 

 Pupae in various stages and many larvae are yet in the earth, and will no 

 doubt go over till next year. The conditions in breeding are evidently 

 unnatural, but vfhy proboscoideus was not influenced equally (being in the 

 same vessel) seems strange. In nature the beetles would certainly have 

 been on hand for the chestnuts when in bloom, at which time they are 

 taken by beating the blossoms. Though only raised by me from chestnuts, 

 this species may breed here in acorns, as I took a $ May r 5th with 

 iiasicus by beating. Dr. Levette, of Indiana, once sent me a set raised 

 by him from Arizona acorns, the beetles appearing in December of the 

 year in which the acorns grew, which in no way differ from those bred 

 from chestnuts. The individuals vary greatly in size (4 to 7 mm.) and in 

 colour. The general colour of the scales and hair is light brown above, 

 paler below ; the thorax has a dark brown discal stripe, limited at the 

 sides and divided longitudinally by a pale yellow line, the elytra being 

 interspersed in various ways with markings of the same colour. I have 

 never seen one entirely unicolorous. The beak of the % is very long 

 and slender, equalling or even exceeding that of the preceding species in 

 proportion to the size ; this and the form of the thorax, which is long and 

 conical, will distinguish the % from all others. The ^ has a shorter 

 thorax, but it is still narrowed anteriorly ; this, with small femoral tooth, 

 oval elytra rapidly narrowed from base, and a yellowish or brownish spot 

 of condensed scales on each side of the central line of the metasternum 

 (occasionally obsolete), will, with practice, distinguish it. 



B. quercus Horn. — This species was bred from all the species of 

 acorns mentioned except the annuals (white and chestnut oak). The first 

 example appeared June roth, and till August ist about one hundred and 

 sixty were observed ; scattering ones have since occurred from time to 

 time, and now the earth contains a few pupte and larvae, but not so many 

 as in the case of rectus. This species seems to have no preference for 

 any of the kinds of acorns mentioned, being reared from each in about
