produced at the apex to a point. The beetles were beaten from a small 

 Cratcegiis growing in a fence corner at the edge of a large grove on June 

 2nd, 6th and 12th, many of them paired: other bushes of the same 

 species nearly yielded none. Tyinnes tricolor is rather abundant, vary- 

 ing in the colour and sculpture of the upper side ; the bronze coloured is 

 the largest and roughest, occurring in June and July, usually on chestnut ; 

 the green variety is found at the same time on hickory, individuals being 

 sometimes bright blue and an occasional one bright coppery. I once took 

 two of the green variety early in April in hibernation, though this is pro- 

 bably an exception to its habit. 



Tymnes chrysis Oliv. — This species when found is abundant, but it 

 seems to occur in localities. So far, it has been taken on hickory 

 sprouts growing from stumps, and occurs in June and July. As it has 

 not been described in American works I give a translation of Olivier's : 

 ^^ Golden-green, thorax a?td elytra punctate; antennce and feet rufous. 

 Like T. viridis ; antennae, palpi, labrum above and feet rufous; 

 body green or brassy-green. Sometimes brassy-green, brilliant, shining \ 

 head, thorax and elytra punctate. New York, Georgia." Oliv., Vol. 6, 

 886, No. 16, and figure. T. viridis Fab. is the green form of tricolor, 

 which is more brilliant in the Southern States, whence were Olivier's 

 specimens. Olivier's description is applicable as far as it goes, but a 

 greater abundance of material shows more variation. The large majority 

 of examples are greenish blue to cobalt blue, while violaceous and bright 

 coppery individuals occur ; in some examples the thorax is of one of these 

 colours and the elytra of another ; the antenna are often darker out- 

 wardly ; the femora are usually piceous black, with the tibiae and tarsi 

 pale. This is varied in different ways, and sometimes all are piceous. 

 The underside is black or piceous, shining, sparsely, finely and irreg- 

 ularly punctate. Length .18 to .20 inch. This species has the thorax 

 and elytra smooth and rather closely and evenly punctate, and without the 

 elytral rugosities of the other species, and arranged by this character it 

 would be the first or the last of the series. 



Rhabdoptera (Colaspis) picipes Oliv. {prcetextata Say). — Olivier 

 describes his picipes as having the thorax finely punctured, and as being 

 a little larger than Tynmes {Colaspis) viridis Fab., the green variety of 

 T. tricolor. It is difficult to find a North American insect in full 

 accord with this description if rigidly interpreted. The bronze form of
