THE CANADIAN ENTOMOLOGIST. 



bred, as I could not obtain last year any hickory nuts containing larvae, 

 but as more success was had this season I hope hereafter to make known 

 whether caryce will be developed. It Ts somewhat difficult to find infested 

 hickory nuts, as comparatively few are attacked. The Carya glabra 

 seems to be preferred, next the C. alba and C. amara, while C. tomentosa 

 and maxima are nearly exempted. From one to eight larv^ will inhabit 

 a single nut, their size not being affected by the number. Many of them 

 never attempt to gnaw out of their bony habitation, but when full fed 

 shrivel up and die. In size they equal the larvge oi proboscoideiis. Some 

 of the nuts are also depredated on by a lepidopterous larva, apparently 

 the same as one of the four species I find in acorns. This is not an 

 inquiline, but feeds on the kernel either with the Balaninus, or by itself, 

 there being seemingly no place of entrance. Two other species inhabit 

 the thick hulls oi tomentosa and alba which I hope to rear. This species 

 averages larger than nasicus, which it much resembles, but differs by the 

 larger femoral teeth ; the tibiae more strongly mucronate at tip, and the 

 narrow hair like (not oval) scales below. The $ beak is rather longer; 

 the last ventral more deeply impressed, and the antennal scape about 

 equals four joints of the funicle. My specimens were bred by Dr. Levette, 

 of Indiana, from C. olivce/ormis, Pecans. 



B. uniformis Lee. — This species was bred from the acorns of all the 

 biennials in about equal numbers, and three examples from those of the 

 chestnut oak ; forty-two specimens were taken in all — not nearly so 

 numerous as quercus with which it was reared. The first example was 

 seen June arst, and none after August ist. The individuals were very 

 uniform in size (5.5 to 6.5 mm. in length) and color, being all clothed 

 with cinereous pubescence of a scaly nature, and the elytral intervals 

 variegated with darker spots. My specimens from Texas and New York 

 are exactly similar. This is not the typical color. The species was 

 described from examples taken at Sacramento, California, and at Steila- 

 coom, Washington, which were " concolorous " and " densely fulvo- 

 pubescent," but colour is of no value in the species of this genus. The 

 nostrum of all the females seen was shorter than the body ; the antennal 

 scape short, about as long as the first two joints of the funicle. The 

 femoral tooth in both sexes is comparatively small, with the posterior edge 

 deeply sinuous. This and the foregoing % characters will help to dis- 

 tinguish this species, but in case of doubt, reference in this, as in all other
