ADEPHAGA. 
This series is by Ganglbauer and others separated from all other 
Coleoptera on account of the wing-venation, the details of the internal 
anatomy, and the fact that the larva has two-jointed tarsi. It includes 
ten families, of which six are commonly found and should be familiar. 
Cicindelim.— Tiger Beetles, 
The clypeus extends laterally in front of the insertion of the antennce. 
The maxillce terminate in an articulated hook. 
With few exceptions, these beetles are generally recognizable in 
the field from their general form, which is distinct from that of their 
allies, the Carabidce. They are often 
brightly coloured, green, brown or 
black with spots or bands of white 
being most common. The majority 
are from one-half to an inch long, few 
under or over these limits. The 
head is short and thickset, in Collyris 
(Plate XVI, Fig. 11), constricted be¬ 
hind the eye into a neck ; the eyes 
are prominent, the antennae moder¬ 
ately long. Long curved mandibles 
project in front of the head, the 
maxillae and labium being conspicu¬ 
ous, the whole mouth-parts evidently

rapidly seizing and firmly clasping 
the insects they feed upon. The prothorax is large and cylindrical, 
the elytra usually smooth or only finely pitted. There are many 
wingless species, and some are very distinctly pubescent. The legs are 
long, slender, finely spined and formed for rapid running. The sexes 
are alike, the three basal segments of the male tarsi often elongated, 
while the males show six, the female seven visible ventral segments. 
The life-history is believed to be uniform hroughout the group, and 
larvae that can be referred with certainty to this family have been found 
in India ; these larvae are found in vertical burrows in the wet sand or
