COLEOPTERA.

in large slabs which had done duty as a rustic covering on an 

 important hut for six or seven years. The larvae feed on the surface 

 wood, just below the bark, 

 making irregular markings, 

 as seen in fig. 52. They 

 pupate below the surface 

 of the bark, and often 

 remain in their burrows 

 after cutting out their 

 exit - holes, or otherwise 

 lodge in the burrows of 

 the bark. In the middle 

 of June they may be dis- 

 lodged by gentle tapping, 

 and thus collected freely.

 covered with a pale pub-

 Elytra rather long, with parallel sides ; legs rather lighter in colour 

 than body, and comparatively slender.

LONGICORNIA. 



This group (so named because of the length of the antennae) is one 

 which the general collector of Coleoptera is very anxious to get well 

 represented in his cabinet. They are of special interest to the student 

 of forest entomology, inasmuch as the larvae are wood-feeders, feeding 

 both in the living stem and on dead timber. 



The larvaa are large, whitish grubs, and in many cases may 

 be easily recognised in consequence of the prothorax being broader 

 than the rest of the body. The head is, as a rule, compara- 

 tively small, and armed with strong mandibles and short anten- 

 nae. The legs, when present, are short or rudimentary, and locomo- 

 tion is often assisted by fleshy tubercules which protrude from the 

 body.
