Coronado, San Diego County, California, in April of the same 

 year, the color varies from testaceous of immaturity to dark nigro- 

 pieeous of maturity. They occur abundantly. 



Form subquadrate oval and strongly convex. 



Labrurn very sparsely punctate; punctures small. 



Epistoma coarsely and rather evenly punctate, the punctures not crowded, 

 scarcely coalescent, although laterally on the lobes they become more closely 

 placed and the surface is distinctly impressed; lobes prominent anteriorly, 

 quite evenly and semicircularly rounded from the sinus to the oblique suture, 

 the latter attaining the margin which is sinuate at that point. 



Front oblique and on almost the same plane as the epistoma; frontal suture 

 rather deeply and narrowly impressed, the epistoma arising more or less 

 gradually from it. 



Mentum large, sides arcuate, often somewhat sinuate behind the apices; 

 margin usually heavily beaded, apex more or less deeply and broadly sinuate, 

 sinus arcuate; surface more or less impunctate centrally toward the apex and 

 rather strong! j' convex; medially toward the base coarsely punctate and usually 

 quite strongly impressed along the lateral margin. 



Proyiolum moderately transversely convex; sides broadly arcuate, more 

 strongly so toward the base; apical angles not deflexed; surface coarsely, deeply 

 and closely punctate throughout, the punctures scarcely differing toward the 

 explanate sides where they are subequal to those on the disk. 



Prosternum coarsely and quite densely rugoso-punctate before the coxae 

 and process; the latter shining, coarsely punctate throughout and more or le.ss 

 distinctly margined between the coxae. 



Male: In this sex the elytra are not strongly inflated and the form is rather 

 more broadly oval with the pronotum more explanate and variable as regards 

 width. 



Female: Rather more oblong with the el3'tra more or less strongly inflated 

 posteriorly. 



Measurements. — Length, 7—7.5 mm.; width, 4-.5..5 mm. 



The only characters to be relied upon for recognition of typical 

 globosus are size and character of pronotal punctuation. The 

 extremes graduate into those of the variety grossus and the latter 

 into its form saginatus. 



Coelus globosus var. grossus Casey 



.Specimens of this variety are at hand that were collected at 

 Santa Barbara, Santa Monica, Redondo, San Diego and Santa 

 Cruz, the latter in Jime. It is the largest form in the genus. 



Size large. Form oblong-oval to oblong-elliptical. 

 Labrum sparsely and distinctly punctate, its surface othersvise glabrous. 

 Epistoma arising very gradually and arcuately from the rather deeply im- 

 pressed suture; surface coarselj- punctate; punctures usually well separated,
