COLEOPTERA.

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

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

 wood, just below the bark, 

 making irregular markings, 

 as seen in fig. 52. They 

 pupate below the surface 

 of the l)ark, 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. 



The perfect beetle is 

 from 3| to 5 mm. long, 

 oblongj of a light ferrugin- 

 ous colour, and slightly 

 covered with a pale pub- 

 escence. Eyes large and 

 black ; antennae slender. 

 Elytra rather long, with parallel sides ; le, 

 than body, and comparatively slender.

LONGICORNIA. 



This group (so named because of the length of the antennpe) 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 larvee are wood-feeders, feeding 

 both in the living stem and on dead timber. • 



The larvae 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 antennae. 

 The legs, when present, are short or rudimentary, and locomotion 

 is often assisted by fleshy tubercules which protrude from the 

 body.
