The basal prominences of the pronotum are relatively large, 

 and when the prothorax is fully extended slightly overlap the 

 sides of the scutellar depression. 



The siitural striae may be slightl}" impressed and the first 

 interval feebly convex as it descends on the basal declivity. 



It may again be stated that the marginal row of scales on the 

 elytra are distinctly narrowed from apex to base, the former 

 rounded, while the next and inner series are less so, becoming 

 fusiform or linear on the central part of the disk, and hair-like 

 around the scutellar declivity. The scutellum has a few long, 

 flying hairs. The elytral punctures are strong and moderately 

 deep. The elytral base is equal in width to that of the pronotum. 

 In the humeral fourths the base is notched and apparently inter- 

 lock with the angles of the pronotum. 



Sexual differences are not evident. Four out of the sixteen 

 specimens of Mr. Martin's series have all of the elytral scales 

 quite linear, but not hair-like nor setiform. In some of the 

 specimens the antennae are gradually and slightly incrassate, in 

 others a three-jointed club is slightly evident. There are prob- 

 ably sexual differences, the}^ are positively not specific. 



Alaudes squamosa new species 



Form oblong-oval, subdepressed and quite parallel. Color testaceo-castane- 

 ous. Head and pronotum densely clothed with appressed scales. Elytral 

 vestiture consisting of sparsely placed capitate scales in interstitial series, those 

 of the central area becoming more slender and in the basal region rather linear. 



Head about a third of its width wider than long, not strongly sinuate at the 

 sides, and the basal angles somewhat more prominent laterally than the anterior 

 angulation; apical margin rather deeply sinuate in middle third, sinuation 

 evenly rounded, lobes evenly rounded into the oblique sides, margin rather 

 narrow and subdiaphanous; surface broadly and feebly im{)ressed in the latcro- 

 basal area. 



Pronotum slightly more than twice as wide as long; sides somewhat promi- 

 nent and moderately arcuate in anterior third, thence convergent and broadly 

 sinuate to become parallel in about basal fourth; apex broadly and moderately 

 deeply sinuate and adapted to the arcuate base of the head; apical angles sub- 

 obtuse and not broadly rounded; base truncate at middle, sinuate laterally and 

 adapted to the humeral region of the elytra; l)asal angles not prominent later- 

 ally, obtuse with the investing scales; disk moderately convex anteriorly, sides 

 of the basal depression rather obliquely precipitous, passing rather arcuately 

 into the horizontal floor; dei)rossion equal to al)out a third of the width or 

 length.
