quadrilineatus by Casey's table — Coleop. Not., III., p. i86 — but the 

 deep basal excavations of the thorax and elytra, as well as the dense 

 punctuation of the former, clearly separate them. The ocular lobes are 

 moderately well developed in basalts, and are said to be wanting in 

 quadrilijieatus. 



Attains subfasciatus, n. sp. — Very small, narrow, depressed, black, 

 thorax with sides behind and base narrowly testaceous, elytra with a 

 slightly antemedian pale fascia which is interrupted at the suture. Head 

 broad, antennte slender, not in the least serrate, reaching the middle of 

 the elytra { ? ), or as long as the entire body ( ^ ), the four basal joints 

 pale. Thorax narrowed behind, of the same form as in Endeodes. 

 Elytra parallel ( (^ ), or posteriorly dilated { 9 )• The pubescence consists 

 as usual of very short semi-erect hairs, with longer erect darker hairs 

 sparsely placed. 



Length, 1.5-2 mm. 



Hab. — San Clemente. 



Described from one^ and eight 9 s. A very peculiar little species, 

 differing in antennal structure, form of thorax and style of elytral color- 

 ation from all other species in our fauna. It may for the present be 

 placed next to lobulatus in which there is a faint indication of the present 

 form of thorax. 



Colaspidea stibvittata, n. sp. — Piceous, with more or less distinct 

 greenish-bronze lustre ; legs, more especially tibias and tarsi, rufescent. 

 Sides of prothorax not strongly rounded, punctuation moderately close, a 

 little coarser on the elytra. Pubescence long (for the genus), recumbent, 

 distinctly subvittate on the elytra in fresh examples. Length, 3.5-4.5 mm. 

 Found abundantly by me on Catalina, also brought from Clemente. 

 There is practically no variation except in size in the large number of 

 specimens examined. The mainland species, on the contrary, exhibit a 

 bewildering amount of variation in size, colour, punctuation, and even in 

 form. One variety of varicolor is of nearly the same colour, but the 

 pubescence is erect and the thorax more strongly rounded at the sides. 

 The pubescence is much more easily removable in siibvittata than in any 

 of the other species, and the vittate arrangement is scarcely evident except 

 in very fresh examples. In the males the antennae are somewhat longer 

 and all the tarsi moderately dilated — characters common to all the species 

 pf the genus.
