ELEODES LATICOLLIS APPRIMA 219 



in size, diffuse or with striae of punctures more or less evident ; base 

 feebly emarginate ; disk rather gradually and arcuately declivous apically, 

 the apex obtusely rounded ; sides arcuate throughout, converging to apex. 



Abdomen finely and sparsely punctured. 



Legs moderate in length. 



Male. Narrower, elongate, subfusiform oval. Elytra gradually nar- 

 rowed posteriorly, rather gradually and arcuately declivous apically ; apex 

 obtusely rounded, sometimes feebly divergent at tip. Abdomen moder- 

 ately convex, first two segments scarcely impressed or flattened. Anterior 

 femora with a slender and well developed tooth. Posterior femora 

 slightly arcuate, gradually widened toward apex. 



Female. Rather robust. Elytra more or less broadly oval, rather 

 strongly although gradually declivous posteriorly ; apex rather more 

 broadly rounded. Abdomen rather moderately and evenly convex. 

 Anterior femora with an obtuse tooth, posterior quite straight. 



Measurements. Length (Types), 22-24 mm.; width, 8.2-9.5 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. Fairfax, Marin County, California, March 9, 1919; 

 E. P. Van Duzee, collector. 



Habitat. As far as known, found only in Marin County, California. 



A moderate series has been studied. Marinae caused considerable 

 trouble until Mr. Van Duzee took a colony which adhered to a common 

 type form. Marinae should precede confinis Blais. in our lists. In con- 

 finis the pronotal sides posteriorly are straighter to the angles than in 

 marinae; there is a shallow and broad sinuation in front of the basal 

 angles, the latter being somewhat prominent laterally in marinae while in 

 confinis the angles are not at all prominent; in confinis the punctuation 

 is fine and indistinct ; in marinae it is less fine, distinct and well defined. 



Eleodes laticollis apprima, new subspecies. Since the publication of 

 the Monograph of the Eleodiini, a large series of specimens of what was 

 then referred to Eleodes laticollis forma insularis, has been studied and the 

 resulting conclusion is that it is a valid subspecies and should be raised to 

 that grade, as indicated above. The material at hand includes collections 

 made on San Nicolas, Prince, San Clemente, Santa Barbara, Anacapa and 

 San Miguel Islands. Material ample enough to force a change of 

 opinion. 



In apprima the pronotum is as a rule a little longer when compared 

 with the width, notably shining, and the form is more elongately robust. 

 The individuals vary in every way as they do in laticollis.
