with five-jointed tarsi ; metathoracic limb, with four large tarsal 

 joints. This contains: u. Tenebrionidae often wingless; 

 mandibles short, strong; antennce 10-1 1 -jointed ; elytra often 

 connate ; many have an ammoniacal smell, or are coated over 

 with a sort of surface secretion ; Blaps, the churchyard-beetle, 

 Tenebrio, the meal-worm, often found in ships' biscuits, 

 belong here. 12. Lagriariac antenna? eleven-jointed, free, 

 pre-ocular; palps larger than the head ; prothorax twice as long 

 as the mesothorax ; larva) hairy, with four ocelli on each side. 

 13. Salpingidae head horizontal, free, not narrowed at base ; 

 antennae clubbed at end ; otherwise as last; larva; with 

 horny plates on each segment, and five pair of ocelli. 14. IV- 

 rochroidoe antenna) thread-like, or pectinate (Pyrochroa) ; 

 head recept ; larva? with enormous penultimate segment, 

 and two pair of ocelli. 15. Melandryadae antennae pre- 

 ocular, thread-like, maxillary palp with large end seg- 

 ment ; larva) with five pair of ocelli ; living in dead wood. 

 10. Mordellidae body long, wedge-shaped ; head vertical; 

 maxillary palp with a knife-like terminal joint ; mandible 

 with a membranous margin internally; eggs lar^e, oval. 

 17. Rhipiphoridae palps with single joints; mandible with 

 no membranous margin; antenna) serrated in females, perii- 

 nated often in males. The larva) of Metoecus paradoxus live 

 in wasps' nests, that of Khipidius blattarum in the abdomen 

 of Blatta. 18. Cantharidida) antenna,- 8-1 i-jointed ; head 

 and neck smaller than the soft, leathery elytra.-. The body 

 pungent blistering substance (Cantharidine). In 



forms the eggs are deposited in the nests of bees, and 

 emit hexapod bristled larva), which are endopara.site. This 

 larva moults, becomes free, then pupifonn, emits a second 



of different shape, fn.ni which the pupa, and finally
