220 NEW SPECIES MELYRIDAE, CHRYSOMELIDAE AND TENEBRIONIDAE 



Measurements. Length (Types), 18-20.5 mm.; width, 10-12.5 mm. 



Holotype, female, and allotype, male, in the collection of the Cali- 

 fornia Academy of Sciences ; paratypes in the Academy's and the author's 

 collection. 



Type locality. San Nicolas Island, March 28, 1918; J. R. Slevin, 

 collector. 



The characters are quite similar in laticollis and apprima ; the former 

 has a relatively more transverse pronotum and is usually dull in lustre. 



Eleodes sanmartinensis, new species. Form elongate, oblong-oval to 

 suboblong-oval. Color black and more or less shining; surface smooth. 



Head about as long as wide, equal to one-half the width of the 

 pronotum ; front slightly convex, punctures small and irregular in dis- 

 tribution, sparse centrally and denser laterally. Antennae extend slightly 

 beyond the base of the pronotum, feebly incrassate apically, last three 

 joints scarcely wider and more or less globular. 



Pronotum about a fifth wider than long; sides evenly and broadly 

 arcuate from apex to base, marginal bead more or less moderate and 

 slightly reflexed ; apex more or less truncate between the rather small and 

 more or less everted apical angles, finely beaded, bead more or less obsolete 

 at middle ; base truncate, rather finely and evenly beaded ; disk evenly and 

 moderately convex, rather narrowly impressed along the sides, punctua- 

 tion fine and more or less obsolete, except laterally where the punctures 

 are more distinct and slightly punctato-rugulose on the impressed area, 

 surface smooth ; basal angles obtuse and more or less distinct. 



Propleura smooth and obsoletely rugose. 



Elytra more or less oval, humeri obsolete; sides. evenly arcuate, in 

 apical fourth evenly converging to the obtuse apex ; base transverse ; disk 

 smooth and more or less indistinctly sculptured ; punctures small and sub- 

 equal, not in the least asperate, apparently more or less serial in arrange- 

 ment, double series sometimes present. 



Parapleura more or less coarsely punctured. 



Sterna not strongly sculptured. 



Abdomen smooth, finely and sparsely punctate, punctures denser on 

 the fifth segment, more or less rugulose. 



Legs long, femora heavy and markedly compressed, anterior femora 

 dentate; tibiae densely punctato-muricate. Tarsi apparently similar in 

 the sexes. 



Male. More or less parallel and elongate oblong-oval. Elytra not 

 wider than the pronotum, more gradually declivous posteriorly. Femora 

 notably stout, long and compressed, the anterior distinctly swollen, tooth 

 at outer fourth, subcylindric, everted and backwardly curved, resulting
