﻿rOLYMORPRA SCAPIIIDIIDAE — SYNTELIIDAE 



229 



Fam. 24. Scaphidiidae. — Front coxae small, conical; prpthorax 

 re i'ii closely applied to tin after-body ; hind coxae transverse, widely 

 separated : abdomen with six or seven visible ventral plates ; 



antennae at the extremity with about five joints that become 

 (//■mini///// brainier. Tarsi Ji ve-joi nted. This family consists of a 

 few beetles that live in fungi, and run with extreme rapidity ; 

 they are all small, and usually rare in collections. Some of the 

 exotic forms are remarkable for the ex- 

 treme tenuity and fragility of the long 

 antennae, which bear fine hairs. The 

 number of described species does not at 

 present reach 200, but the family is very 

 widely distributed. We have three or 

 four species in Britain. All we know of 

 the larvae is a description of that of 



Fk;. 108. — Scaphisoma agari- 

 cinuvi. Britain. A 

 Larva (after Perris) ; B 

 perfect Insect. 



Scaphisoma agaricinum by Perris; it is 



like the larva of Staphylinidae, there are 



nine abdominal segments in addition to a 



very short, broad pseudopod, and very short 



cerci. This larva feeds on agarics : it goes through its development 



in about three weeks ; unlike the adult it is not very active. 

 Fam. 25. Synteliidae. — Antennae clavicorn, with very large 



<■/ nli : labium, with hypoglottis and the parts beyond it, exposed. 



Fnmt coxae transverse. Abdomen with five visible centred segments, 



and eight or nine dorsal, the basal four of which eire semi-corneous. 

 This family includes only five species; its clas- 

 sification has given rise to much difference | 

 of opinion. We have, after consideration 

 of all its characters, established it as a 

 distinct family 2 allied to Silphidae. The 

 perfect Insects live on the sap running from 

 trees : but nothing else is known of their 

 natural history. Like so many others of 

 the very small families of aberrant "Cole- 

 optera, it has a very wide distribution ;
