GLYPTOSCELIS, NEW SPECIES 197 



Elytra less than half longer than wide, rather broadly and obtusely 

 rounded posteriorly ; sides very feebly arcuate, humeri moderately nar- 

 rowly rounded, umbones rather distinct ; base very slightly emarginate ; 

 surface strongly transversely convex; punctuation somewhat finer than 

 on the pronotum, punctures separated by a distance equal to about twice 

 their own diameter, still finer on the apical declivity. Scutellum slightly 

 transverse, apex feebly angulate, surface with a few small punctures. 



Abdomen rather more thickly punctate than above. 



Legs comparatively short and rather stout. Anterior tibiae quite 

 straight; middle and posterior tibiae slightly outwardly curved at apex. 



Claws cleft. In the male the anterior claws are cleft to slightly 

 behind the middle ; the inner divisions are one-fourth shorter than the 

 outer part and rather acute. In the female the anterior claws are cleft 

 to the middle, the inner divisions are short and acute, scarcely separated 

 from the outer part ; claws of the middle and posterior tarsi similar, 

 more distinctly cleft to about basal third, inner portions longer, more 

 slender and acute. 



Male. Narrower. Rather broadly impressed at middle of the fifth 

 ventral segment, this impression impunctate or more or less sparsely 

 punctate and pubescent. 



Female. Broader. Fifth ventral rather moderately concave 

 throughout the width and apically more or less arcuately deflexed. 



Measurements. Length (Types), 5.5-7.5 mm.; width, 3.8-3 mm. 



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

 fornia Academy of Sciences ; paratypes in the collection of the Academy 

 and in that of the author. 



Type locality. Sacramento, California. Collected by E. P. Van 

 Duzee, May 28, 1918. Beaten from wild rose. 



Parvulus somewhat resembles Adoxus vitis Fab. in form, but is rather 

 narrower and more elongate. The individuals vary quite a little in form, 

 some are shorter and more robust than others and intermediates are 

 abundant. It is the smallest species known to the author. In all species 

 of Glyptoscelis examined there is a rounded setigerous fovea at the apical 

 and basal angles of the pronotum. 



In pubescent, illustris and sequoiae there is a circum-scutellar depres- 

 sion and an impression within the humeral umbones. The latter impression 

 is also present in parvulus. 



The two species here described cannot be the same as albidus Lee., 

 where the pubescence is very easily removable according to Dr. Horn. 

 A species taken in El Dorado and Calaveras Counties answers the latter 

 peculiarity very well. In illustris and squamulatus the vestiture is quite 

 persistent.
