low ground until Spring before they become pupae. I have found 

 as many as six full-grown larvae in one acorn of Q. rubra. As 

 the beetles appear in May and June it is curious what becomes 

 of them during the Summer. I have taken the beetle at large 

 August 28th. 



Pairing takes place upon the acorns in September, at the time 

 of oviposition. It is probable that we have but one species in 

 America, the characters given in the table above being insufficient 

 to separate species. The concave first ventral distinguishes the 

 males. 



The Tineid Acorn Moth (Holcocera glandule/la Riley). 



The lavender-tinted larva muturing in early August spins in 

 the partially-grown acorn of Q. coccinea while the acorn is yet 

 covered by the cupule, the opening it prepares being eaten 

 through both cupule and shell ; one found August loth had 

 emerged through an opening close to the stem. A later brood 

 of the same lavender-tinted larva occurs in acorns of Q. coccinea 

 and Q. rubra in December, having taken the place of Balaninus 

 and closed the beetle's exit holes with silk. The figure in Fifth 

 Report U. S. Ent. Comm., may represent this brood. This 

 Gelechia (Lavcrna, Blastobasis or Holcocera, as it has been vari- 

 ously called) is double brooded, the Autumn brood being inqui- 

 linous as described by Prof. Riley and Miss Murtfeldt, the 

 Summer brood being independent. The larva has been described 

 as pinkish, yellowish or grayish white. It is actually of a pale 

 lavender tint.

The insects figured on the accompanying plate were not chosen 

 for illustration, because they belonged to particularly interesting 

 species ; but because they presented marked contrasts in color 

 and ornamentation, hence, making a more thorough test of this 

 method of illustration. A pen-drawing was made of the insects- 

 scale, one and a half-inches to the inch ; and, in making the 

 half-tone plate, a two hundred mesh to the inch screen was used.
