into the broadh* sinuate apex; base, as a whole, moderately arcuate, squarely 

 truncate in middle two-fourths, sinuate laterally and adapted to the elytral base 

 at the humeri; basal depression large and broadly arcuate anteriorly, projec- 

 tions rather stfong, distinctly touching the side of the scutellar depression; 

 basal angles almost rectangular, narrowly rounded including the investing 

 scales; disk strongly arcuate anteriorly and laterally. 



Elytra about three times as long as the pronotum and about a third of their 

 width longer than wide; disk moderately convex, punctures coarse, round and 

 rather shallow, quite obsolete at base and on the scutellar decHvity; sides mod- 

 erately arcuate, converging from about the middle in an arcuate manner to the 

 paraliolically rounded apex; vestiture long, slender and hair-like, widely 

 spaced in interstitial series. Scutellum apparently oblong-triangular and 

 transverse, the sparsely placed hairs somewhat coarse. 



Measurements. — -Length, 1.5 mm.; width, O.G mm. 



Habitat. — San Diego, California. Taken in company with 

 ants. One specimen in the author's collection. 



Setigera is quite distinct from either singularis or squamosa, the 

 head is transverse, the pronotum longer and less transverse, 

 elytral vestiture hair-like, form more robust, the basal angles of 

 the head are more prominent and sharper and the lateral sinuation 

 is more sharply reentrant. 



Alaudes testacea new species 



Form oblong-oval, somewhat depressed. Color testaceous. Head and 

 pronotum clothed with yellow ap pressed scales, some of which are apparently 

 larger than the majority. Elytral vestiture consists of sparsely arranged erect 

 scales in interstitial series; the marginal scales are strongly capitate, becoming 

 less capitate centrall3\ 



Head moderate in size, about a third wider than long, anterior angulation 

 less prominent than the subobtuse basal angle, sinuation rather shallow, sides 

 oblique anteriorly; apex moderately deeply sinuate in middle third, sinuation 

 evenl}^ rounded, lobes evenly arcuate, margin narrowly subdiaphanous; base 

 rather strongly and broadly arcuate in middle three-fifths, somewhat oblique 

 and apparently very feebly sinuate laterally; surface feebly convex centrally, 

 broadly and vaguely impressed laterally and apicjally. 



Pronotum distinctly transverse and about a third of its length shorter than 

 the head, more than twice as wide as long, base about equal to apex; sides 

 moderately arcuate anteriorly, thence oblique and somewhat feebly sinuate and 

 subparallel before the basal angles, the latter obtuse (c?) to somewhat promi- 

 nent ( 9 ) posteriorly; apex broadly sinuate, angles subobtuse; base somewhat 

 arcuate as a whole, sinuate laterally and adapted to the humeri; depression 

 about equal to a third of the width, sides rather precipitous, passing quite 

 arcuately into the floor, the latter flat with posterior border transverse or feel^ly 

 arcuate ; disk moderately convex, basal prominences rather strong.
