150 THE CANADIAN ENTOMOLOGIST. 



The larva of Cicindela (fig. ii, C vtclgaris) is a somewhat 

 elongate, whitish grub, with a broad, metalUc coloured head and 

 prothorax, and a large hump, bearing two hooks, on the fifth 

 abdominal segment. They excavate holes in sunny spots and 

 lie in wait for prey, with the head closing up the mouth of the 

 '^* "■ burrow ; when an insect comes within reach it is seized 

 by the long jaws of the larva and the juices extracted. I am now 

 rearing larvae of C. limbalis, Klug, which I dug from holes in a 

 clay bank on the fifteenth of April. They are easily kept in little tin 

 boxes with damp earth, and feed readily on soft-bodied larvce of wood- 

 borers. The pupa is figured by Letzner * and is represented as bearing 

 on the fifth abdominal dorsal, two long spines corresponding to the 

 hooks on the same segment in the larva. 



The perfect insects are to be found in all parts of North America 

 south of the sixtieth parallel, or at least extend very nearly that far 

 north, though more numerous in warm climates. The colours are 

 usually metallic, the elytra more or less spotted and banded with white. 

 When these markings are of the style shown in the figure of C. hirticollis 

 (fig. 1 6) they are said to be coinplete ; if, as is sometimes the case, they are 

 reduced to partial obliteration or breaking up of these bands, they are 

 called incomplete. The curved mark on the shoulder is known as the 

 humeral lunule, the one at the tip the apical lunule, while the long bent 

 mark extending nearly across the middle is called the median band. An 

 important character, which is to be used in assigning species to their 

 proper places in the table, is to be found in the labrum or upper lip; in 

 most of our species it is short, but in C. longilabris it is very long. The 

 free edge is variously toothed in the Canadian species. The legs furnish 

 no characters that we can employ with profit, but it will be noticed that 

 the males have three joints of the anterior tarsi dilated and silky 

 pubescent beneath, the middle tibipe being pubescent on the outer side. 



Of the twelve tiger-beetles reported from Ontario and Quebec, the 

 following five are considered varietal forms only : — C Lecontei figures as 

 a variety of sctite/Iaris, limbalis and splendida both belong to ptcr- 

 purea, generosa is an Eastern form oi formosa, and 12-guttata is subordi- 

 nate to repanda, being simply a variety in which the bands are broken 

 up. The variety of longilabris, which is called perviridis, is known from 

 Newfoundland, but I think not from the provinces which are directly the
