Coleopterological Notices, VI. 589 



The material in my cabinet seems to indicate the three follow- 

 ing species : — 



Submarginal line of the pronotuni entire, extending to the apex. 



Sides of the prothorax sinuate near the basal angles, which are right and 



somewhat prominent 1. SCUlptili^ 



Sides ahiiost evenly and feebl3- arcuate, not more than straiglit near the 

 basal angles, which are obtuse and not at all prominent. . .2. denudatus 

 Submarginal line abruptly abbreviated at apical fourth or fifth of the length ; 

 basal lobe of the prothorax more gradually formed and less pronounced. 



3. disjiinctus 

 Allonyx seems to be limited in its range to the coast regions of 

 middle California from Sta. Barbara to Mendocino, being perhaps 

 still more circumscribed than Eschatocrepis. Many California 

 trees are well known to be similarly limited in range, such as 

 Sequoia and Pinus insignis.

Oblong, subparallel, moderately convex, rather dull and aluta- 

 ceous in lustre, black with a feeble greenish tinge, the elytral 

 apices rufescent apparently in great part from diaphaneity ; legs 

 rufo-ferruginous, the hind femora on the upper edge near the tip 

 and the corresponding tibiffi infuscate; antennie pale testaceous, 

 the first and eleventh joints in part darker; mouth parts and lab- 

 rum pale, the palpi dark at tip. Head thi'ee-fifths as wide as the 

 prothorax, with two large impressions coalescent behind the 

 transversely convex separating surface, the occiput thence finely 

 striate along the middle to the base ; ej'es rather large, convex 

 and basal ; antennae somewhat stout but filiform, not incrassate, 

 one-third longer than the prothorax, the fifth joint long and dis- 

 tinctly wider. Prothorax transverse, parallel, the sides feebly 

 bisinuate, the disk minutely, sparsely and not very distinctly 

 punctate, the submarginal lines entire, extending to the apex. 

 Elytra three-fifths longer than wide, one-fourth wider than the 

 prothorax, feebly dilated and Avith the sides somewhat arcuate 

 behind, the apex broadly rounded ; lateral edges somewhat re- 

 flexo-explanate ; punctures fine, rather sparse and xevy indistinct. 

 Abdomen black throughout. Length 3.3 mm.; width 1.35 mm. 



California. The single specimen before me is a female, said by 

 Mr. Dunn to have been taken by him in the vicinity of San Fran- 

 cisco ; it is a female, as proved by the extruded genitalia, but the
