WICKHAM — THE HABITS OF AMERICAN CICINDELID.-E. 227

quite well defined, to a separation of the anterior portion in the form 

 of a dot. Under side of body bronzed with green and golden reflec- 

 tions, trochanters and abdomen reddish, legs cuprous. Length, 1 1 mm. 

 Compared with a male xQipuuctata from Luna, New Mexico, arizonce 

 has the head rather more distinctly rugose, the elytral sculpture a trifle 

 coarser, while the sutural spine and the serration of the elytral apices 

 are much better marked. The labrum is formed exactly as in id piinc- 

 iata. Both pairs of palpi are pale at base in my specimens, which are 

 males. Mr. Roland Hay ward sent me specimens labelled " Grand 

 Caiion of the Colorado" and I have since received the same thing 

 collected by Professor Townsend, who writes: '•'! collected the species 

 in the Grand Caiion during the first two weeks of July, 1892. It 

 occurred on sandy places or along paths by a stream going down a 

 side canon, from 2500 feet above, down to the level of the Colorado 

 River. Or from 5000 feet above sea (at Hance's stone cabin, 2500 

 feet below the rim and about two or two and a half miles down the 

 trail from river) quite to the bottom of the canon, which is here 2500 

 feet above the sea. The insect is not especially wary." 



C lientzii Dej. Mr. Roland Hayward tells me that it is found on 

 rocky, more or less wooded hillsides, usuallv sunning on bare rocks. 

 It occurs alone and scattered. He cites several localities in eastern 

 Massachusetts, i.e., Milton, Medford, Gloucester, Brookline, West 

 Roxbury. It flies from June to August. Dr. A. A. Gould, in his 

 ' ' Cicindelse of Massachusetts, ' ' writes : ' ' This very interesting species 

 was discovered by Dr. T. W. Harris on the summit of Blue Hill in 

 Milton. It does not prefer the sand and the plain, but its habit is to 

 bask on the broad flat masses of granite which rise above the soil, retir- 

 ing to the patches of moss and lichen which vegetate in the crevices. 

 When flying in the sunshine its crimson and nearly transparent abdo- 

 men appears like a drop of blood suspended to its tail." 



C. marginipennis Dej. "On the banks of the Susquehanna below 

 the bridge at Harrisburg ; banks of the Delaware near Callicoon," 

 (Schaupp). Mr. Nathan Reist informs me that he takes it on sandy 

 soil or more or less on cobblestones on river bars at Marietta, Penn- 

 sylvania, from the middle of June to the first of September. It occurs 

 in swarms but is difficult oi capture on account of a peculiar habit. 

 They are very watchful and stand on the round stones. As soon as 

 the net falls over them, instead of flying up they run out from beneath, 

 the inequalities produced by the pebbles keeping the net from lying flat.
