LITODACTYLUS, Kedtenbaeher. 



Two species belong to this genus, one from Europe and one from 

 Ceylon ; they differ from Eubrychius, which they very closely resemble 

 in habits, in the fact that the tibiae and tarsi are not furnished with 

 cilia, and from Phytobius by having the antennae inserted in the middle 

 of the rostrum, and the legs longer and more slender with the last tarsal 

 joint elongate ; the claws are long and simple ; the club of the antennae 

 is ovate ; the thorax is furnished with f our tubercles of which the 

 posterior pair are the most distinct. 



L. leucog-aster, Marsh (myriophylli, Gyll ). Black, dull,, upper 

 surface somewhat depressed on disc, underside thickly clothed with 

 white scales, as well as the sides of the thorax and a spot at the base of 

 suture ; the elytra are besides more or less distinctly variegated with 

 greyish scales and sometimes have a slight silvery reflection ; scape of 

 antennae and the legs yellow, knees and tarsi, and sometimes more or 

 less of tibiae, black ; thorax narrowed in front, but scarcely constricted, 

 with a channel extending for its whole length, and with four tubercles, 

 two, more or less indistinct, at anterior margin, and two large pointed 

 ones on each side at base ; elytra much broader than thorax with rather 

 deep striae, fifth interstice elevated at base. L. 2| mm. 



Male with the intermediate tibiae armed with a small hook.

PHYTOBIUS, Schmidt. 



This genus contains upwards of twenty species which are found in 

 Europe and North America ; they are short and broad insects with a 

 short stout rostrum and ten-jointed antennae which are inserted in front 

 of the middle of the rostrum ; the tarsi have the last joint not elongate 

 and the claws are either simple (Phytobius, i. sp.) or appendiculate on 

 their inner side (PachyrrMnus, Steph.) ; the species are sub-aquatic iu 

 their habits, but do not live or undergo their transformations beneath 

 the water, as is the case with the two preceding sub-genera ; an account 

 of the larva is given by Chapuis and Candeze (Catalogue des Larves des
