All remarks about larv.-e under Afaniloha in my first paper should be 

 referred to rrnnstti. Fuller observations have shown that owing to the 

 great depth at which it hibernates, Afaniioba is the last tiger beetle to 

 appear in the spring. In 190S adults remained in winter ipiarters until the 

 end of May, and larv.-e still later. 



Vmiistti, I.cc. — \'otmg larv;v appear about the first of July, and at 

 once proceed to deepen their burrows to a foot or more in the course of a 

 couple of weeks. They then remain active, excepting while moulting, 

 until the middle of October, during which period they grow very rapidly, 

 and at the approach of winter deepen their burrows considerably, and after 

 closing them remain dormant at the bottom throughout the winter. They 

 then appear again in May, close their holes in June, and usually remain 

 inactive until August, the burrows are then opened up and deepened to 

 the extent of a few inches, closed in October lor a second winter, and 

 reopened the following spring. About the middle of June the larvfp 

 construct a side chamber, starling from half an inch below the surface and 

 branching ofT from the original burrow. 'I'he chamber varies in length, 

 but averages three inches, and is generally about the same in depth at its 

 extremity, where it is widened out into a chamber, about twice the width 

 of the entrance. In this the larva changes to a pupa facing the top. 

 Holes were observed closed on June 22, and by July 10 two larva- had 

 become shortened, evidently changing to pupa>. The first pupa was 

 discovered July 15. This was situated about the middle of the pupnl 

 cavity, not in the largest part. (.)n August 10 two imagoes were found 

 still in the pupal cell. Both ran actively when dug out, and one made 

 several short flights. On .August 19 a large number of pupal chambers 

 were examined, and only three adults found, all of which had partly dug 

 out. Hy the 20th of August several beetles were digging winter quarters, 

 and by September ist most of them had disappeared below the ground. 



The life of the adult is slightly shorter than .\f,viitol'<i, but oltl 

 in«li»idualb have been found in Septeniber. l.arv:i' show no signs of con- 

 stiueling pits, the holes being perpendicular throughout their tntite 

 length. Of a large number of second year brval holes measured at the 

 approach of winter, the average depth was 45 inches, the shallowest 32, 

 and deepest 55 inches. Voung larv;e were usually several inches 

 shallower. 



Limluilii, Say.— The larva: of this species appear from eggs at about 

 the same date as 'irnui/n, and like that species are often at first found
