A REVISION" OF NORTH AMERICAN CHRYSOBOTHRTNI 235 



granulosa, each elytron ornamented with violaceous spots as follows: A small, 

 round spot at basal third, a transversely triangular spot behind middle, and an 

 irregular, oblique spot near apex. 



Abdomen beneath sparsely, coarsely, shallowly punctate, the punctures open 

 posteriorly, clothed with a few short, inconspicuous hairs, without lateral cal- 

 losities, intervals densely granulose; last visible sternite thickened and trans- 

 versely sinuate at apex, with margins strongly deflexed, without a submarginal 

 ridge, lateral margins not serrate; eighth tergite coarsely, deeply, confidently 

 punctate, densely granulose, broadly rounded at apex. Prosternum coarsely, 

 confidently punctate, transversely rugose and declivous anteriorly, clothed with 

 a few short, inconspicuous hairs ; anterior margin transversely sinuate, deflexed, 

 without a median lobe. Anterior femur with a broad, short, obtusely angulated 

 tooth, which is vaguely dentate on outer margin. Anterior tibia moderately arcu- 

 ate, unarmed at apex ; middle tibia slightly arcuate ; posterior tibia straight. 



Length 14 mm., width 6 mm. 



Male. — Unknown. 



Redescribed from a female in the United States National Museum, 

 collected on agave during August at Fort Bliss, Tex., by B. Shimek. 



Type locality. — Texas. Described from a single female in the Ulke 

 collection, but the present location of the type is unknown to the 

 writer. 



DISTRIBUTION 



From material examined : 



Texas: Fort Bliss, August (B. Shimek). Marathon, Brewster County, August 

 26-27, 1912, 3,940 to 4,160 feet elevation (Rehn and Hebard). 



Chamberlin (1926) records the species from Amedee, Calif., in July, 

 at an elevation of 4,200 feet. 



Host. — The larval habits are unknown, but Mr. Shimek collected 

 an adult on agave at Fort Bliss, Tex. 



Only two females have been examined by the writer and no varia- 

 tion has been observed except in size and in the violaceous markings 

 on the elytra. In the specimen from Marathon the three triangular 

 spots on each elytron are narrowly joined to one another near the 

 sutural margin, whereas in the specimen from Fort Bliss the spots 

 are widely separated and the anterior one is only vaguely indicated. 

 The length is from 14 to 17 mm. 



LeConte described this species from a single female in the Ulka 

 collection. Horn (1886) figured the pronotum of the type loaned to 

 him by Mr. Ulke. The type is recorded as being in the Ulke collec- 

 tion in Pittsburgh, but Mr. Buchanan examined the specimens in that 

 collection for the writer, and was unable to locate the type. It is just 

 possible that Mr. Ulke loaned this specimen to some person before 

 the collection was sent to Pittsburgh.
