almost globular, third still smaller, but longer than broad, the fourth as 

 broad as long, the remainder broader than long, joints three to eight grad- 

 ually increasing in breadth, the ninth, tenth and eleventh suddenly en- 

 larged and forming a loosely jointed club. Head broader than long, one 

 half breadth of thorax, coarsely variolately punctured, front flattened, 

 eyes moderate in size but distinctly smaller than in G. pilosula Cr. Thorax 

 twice as wide as long, disc moderately convex and finely sparsely punc- 

 tured, sides depressed, widely explanate, the expanded portions together 

 over one third the breadth of thorax and with punctuation coarse and 

 closer than on disc, basal margin with median half slightly lobed, the outer 

 parts just perceptibly rounded, hind angles well rounded, side margin 

 evenly and gradually arcuate, finely serrulate, and somewhat convergent 

 to anterior angles which are well rounded, anterior margin deeply and 

 semicircularly emarginate. Elytra with breadth two thirds of length, 

 about three times as long as thorax, breadth at base the same as breadth 

 of thorax, thence gradually increasing to posterior two thirds, disc quite 

 flat, sides suddenly depressed below disc and explanate, the expanded 

 margin almost as wide as in the thorax, surface moderately coarsely and 

 sparsely punctured, each puncture with a short, yellow procumbent hair 

 arising from it, side margins very finely serrulate, apical angles shghtly 

 and individually rounded. Beneath very finely and sparsely punctured 

 and finely and sparsely pubescent. 



Length 5 mm., breadth 2.25 mm. 



Type: A unique in my own collection. 



My specimen I owe to the kindness of Mr. J. C. Bridwell, who 

 collected it on Mt. San Jacinto in Southern California, in July, 

 1 91 2. Two other specimens have been seen, a male and female, 

 a pair in the collection of Mr. Ralph Hopping. They were collected 

 from beneath the bark of cedar, Libocedrus decurrens Torr. at 

 Cascada, Sierra National Forest, Fresno County, California, 

 June I, 191 5. Both have the head and abdomen somewhat 

 piceous, darker than in type, and the female has the punctuation 

 of elytra somewhat coarser than in the male and than in my 

 specimen, which is also a male, otherwise they are the same. 

 The male is 5 mm. in length and the female 6 mm. It is inter- 

 esting to note that this pair were taken from beneath dead bark 

 where both G. quadrilineata Melsh, and G. oregonensis Cr. are 

 to be found, while G. pilosula Cr., though very common, has 

 always been taken in flowers, chiefly those of Ceanothus, the so- 

 called wild lilac. 



This species in size and general appearance is like G. pilosula
