punctate, but in their case the opening on the aedeagus appears to 

 be situated still farther from the tip. A small series from Los Angeles, 

 Calif,, appears to be a little more coarsely punctate than the typical 

 ones, and the aedeagus is a little wider. 



MONOXIA APICALIS, new species 



Plate 18. Figure 5 



Small (about 3 mm.), in shape and markings similar to darkly 

 marked specimens of M. sordida, but less densely pubescent, with the 

 punctation distinctly visible, the elytra even somewhat shining; 

 claws of both sexes toothed. Head densely punctate and lightly 

 pubescent, with the median line impressed and a slight callosity on 

 either side of the vertex near eye; a dark occipital spot sometimes 

 extending down front to below eyes; front usually pale and labrum 

 dark. Antennae pale, often with darker outer joints. Prothorax 

 fully twice as wide as long, with the sides slightly rounded and with 

 a small tooth at the basal angle; disk widely depressed at sides and 

 in the middle; the pubescence partly concealing the rather dense 

 punctation; usually pale with dark median and lateral spots, these 

 often coalescing. Elytra somewhat depressed, with an intrahumeral 

 depression that extends downward and inward about one-third the 

 length of the elytra; densely and distinctly punctate, the pubescence 

 moderately long but not at all obscuring the punctation; heavy dark 

 markings usually predominating over the pale, the pattern similar 

 to darldy marked specimens of M. sordida, with the apex pale. Body 

 beneath shining, sparsely pubescent, more or less darkened ; legs usu- 

 ally pale, with a dark ring about middle of femora and tibiae; claws 

 of both sexes toothed. Length, 3 to 3.5 mm.; width, 1.4 to 1.7 mm. 



Type, male, and 3 paratypes, U. S. N. M. No. 44029, collected by 

 H. K. Morrison; 8 paratypes in collection of the Museum of Com- 

 parative Zoology, Bowditch collection, Cambridge. 



Type locality. — Arizona ("No. Sonora, Mexico"). 



Distribution. — Arizona (Higley, Galiuro Mountain), California 

 (Palm Springs). 



Remarks. — Jacoby ^^ figured this species in the Biologia Centrali- 

 Americana as M. guttvlata LeConte. It is a much smaller species 

 than guttulata and belongs to a different group, being closely related 

 to M. sordida. It has a similarly shaped short, wide prothorax, and 

 the claws are toothed in both sexes, as in sordida. The abdomen of 

 the male, however, is more distinctly truncate than in most specimens 

 of sordida. It is also distinguished from sordida by having less 

 pubescent elytra, which are somewhat shining and the punctation 

 of which is coarser and distinctly visible. The prothorax also appears
