NORTH AMERICAN COLEOPTERA. 137 



GL,\I»TOS€EL,IMORPHA n. g. 



This name is proposed for a genus of Buprestidte allied to Schizo- 

 pus and Dystaxia, with the following characters : 



Form cylindrical, slightly depressed, slightly narrowed in front, 

 obtuse posteriorly. Head deeply inserted, front nearly vertical, 

 clypeus slightly prolonged, broadly eniarginate ; labrum transverse, 

 with rounded angles, slightly eniarginate in front. Eyes moderately 

 prominent, broadly oval, entire. Antennae slender, scarcely at all 

 serrate, nearly half as long as the body, first joint stout, second oval, 

 small, third longer than first, fourth a little shorter than third, 

 fifth equal to third, joints five to ten gradually shorter, eleventh 

 half as long as tenth ; maxillary palpi moderate in length, slightly 

 thickened to tip, last two joints equal in length, subcylindrical. 

 Thorax broader than long ; scutellum oval, broader than Ions:. 

 Elytra nearly parallel, obtuse at tip; prosternum slightly narrowed 

 between the coxse, tip obtuse, received in an emargination of the 

 ventral mesosternum ; metasternal episternum broad, nearly twice 

 as wide as long, slightly broader in front, epimeron small ; first two 

 vertical segments closely united with scarcely a trace of suture, 

 these two at the sides as long as the three following segments, the 

 third to fifth gradually decreasing in length. Legs not long, femora 

 rather stout, tibiae slender, with two terminal spurs; tarsi moderate 

 in length, shorter than the tibife, the first three joints with a short 

 lobe, the fourth with a long, deeply divided lobe; first joint of hind 

 tarsus about as long as the next two ; claws divaricate, broadened at 

 base, but not toothed. 



The relationship of this genus with the other two forming the 

 tribe Schizopini, may be expressed in the following manner : 



Antennse slender, nearly filiform, scarcely at all serrate. 



Claws entire at tip, slightly thickened at base; last joint of anteunfe nearly 



one-half shorter than the tenth Glyptosceliinorpha. 



Claws cleft at tip; last joint of antennse very little shorter than the tenth. 



Dystaxia. 

 Antennffi flattened, the joints 4 — 10 broader than long and distinctly serrate. 

 Claws cleft at tip ; last joint of antennfe oval, longer than the tenth. 



Schizopus. 

 These genera all occur in southern California. 



G. inarinorata n. sp. — Sub-depressed, cylindrical, brassy-bronze, shining, 

 surface irregularly marmorate with patches of short, recumbent, cinereous pu- 

 bescence. Antennse brownish testaceous, the terminal joint black ; labrum 

 yellow. Head moderately coarsely closely punctate. Thorax a little less than 

 twice as wide at base as long, slightly narrower in front, sides nearly straight,
