Lioptiira Iitildeinaiii Casey, 1891, An. N. Y. Acad. Sci. vi, 12. 

 Li'nj;tli !l 1(1..") mill. = .36-.42 inch. Habitat. — New Mexico. 

 Described ii.s .^lender and ratlier convex, the body intensely l)lack ; 

 lei^s. antennie and elytra! humeri red; moderately shining ; pubes- 

 cence sparse and inconspicuous; anteniue male) nearly as long as 

 the body ; thorax much longer than wide, like that of sauf/uitiea ; 

 disc extremely densely punctate; elytra not coarsely nor densely 

 punctate, narrowly truncate at tip. ^[ay be })laced in the table near

Length 7.8-9 mm. (female); 9-11 mm. = .36-.44 inch, (male) = .31-.36 inch. 

 Habitat. — Michifjan (Marquette). 



Described as haying the body, legs and antennae entirely black, 

 the elytra pale brownish testaceous, sometimes feebly infuscate toward 

 the a])ex ; moderately shining ; pubescence moderately long very 

 short on the elytra. The males are larger tlian the females and the 

 sexual differences throughout the body unusually well marked. Al- 

 lied to lianguhiea Lee, but differs in the much stouter male antennje 

 and in the truncation of the elytra being not broad and strait, but 

 narrow, oblicjue and deeply sinuate, nearly as in canadetisu. 



OI>III^iTO:?III«i Thorns. 

 This genus is only sej)arubU' from Lcpturd by the head being ])ro- 

 longed into a beak. It is re{)resented in our fauna by two species.

Length 11-12 mm. ^ .42-.47 inch. Hnlritat. — Southern California, Lower Cali- 

 fornia (El Taste). 



"Slender; head black, closely punctate : thorax red or black, conical, longer 

 than wide at base, ajiex constricted, sides compressed behind the middle, disc very 

 convex, very sparsely and finely imnctate. hind angles not explanate. Elytra 

 wider at base than the thorax, humeri jirominent, sides obliquely narrowing, 

 apex obliquely emarginate-truncate, the angles acute, disc coarsely and deeply- 

 not regularly punctate, punctures finer toward apex. Pro- and mesosternum 

 black. Metasternum and abdomen red, very sparsely finely punctate, not i)ubes- 

 cent. Legs black, the underside of hind femora at base usually red. The vesti- 

 tiire of the upperside consists of very short black hairs arising from the ])unctures. 

 Allied to ntjiveutria Bates from Nicaragua, but ditlers in its almost smooth thorax."

The synopsis of the Cerambycidit, now brought to a close, was 

 commenced in 1884, and published from time to time, in parts, as
