the aedeagus to make it a distinct species. In its general appearance 

 it is a much paler beetle due to its coarse and dense white pubescence, 

 in which the brown hairs are coarser and fewer than are those of 

 G. illustris. There is very little elytral surface to be seen because 

 of this dense pubescence, whereas in G. illustris the shining, even 

 coppery, surface is very apparent. 



Glyptoscelis cylindrica, new species 



Figure 20 



About 7 mm. in length, elongate oblong oval, almost cylindrical, 

 shining black, densely and coarsely punctate and with a very fine 

 erect yellowish or grayish hair from each puncture, hairs on under- 

 surface more appressed, legs and antennae deep reddish brown. 



Head with interocular space considerably more than half width of 

 head, eyes with tiny emargination at antennal socket, occiput and 

 front coarsely and contiguously punctate, a small depression in middle 

 of front, a semierect fine silken hair from each puncture, head shiny 

 piceous except for reddish-brown labrum. Antennae extending 

 slightly below humeri, basal joint globular, joints two to five thinner 

 than outer joints, seventh joint long. Pro thorax as wide as elytra 

 and approximately as wide as long, strongly convex, sides rounded, 

 disc slightly depressed along base, punctures dense and each with a 

 fine hair. Scutellum unusually broad and short, punctate. Elytra 

 deeply and almost contiguously punctate, each puncture with a long, 

 erect, silky pale hair, producing a fuzzy effect, humeral prominences 

 lacking (probably a wingless beetle), otherwise without depressions. 

 Body beneath shining, slightly less coarsely punctate, the pale pubes- 

 cence more appressed but not coarser; legs reddish brown, covered 

 with long, semierect pale hairs, tibiae rather short. Length 6.8 mm.; 

 width 3.1 mm. 



Type: ?female, in California Academy of Sciences. 



Type-locality: Cotati, Sonoma County, Calif., May 5, 1948, E. H. 

 Calkins. 



Remarks: This is the most aberrant in appearance of any species of 

 Glyptoscelis, yet it is undoubtedly of that genus. The fuzzy silky 

 hairs that are not appressed but erect, and the lack of humeral prom- 

 inences are its most distinctive characters. Otherwise it resembles 

 other species of the genus with its coarsely punctate dark surface, its 

 sulcate tibiae and toothed claws. Only one specimen is known. 

 That the beetle probably is wingless doubtless explains the limitation 



of its distribution.
