TA]5ri'MECINr. 83 



Form oblong, oval, densely covered with pale -blue scales Avitli a fiiint 

 cupreous lustre. Body winged. Head sparsely punctured, densely scaly. 

 Thorax broader at base than long, narrower in front, sides moderately 

 arcuate, apex faintly lobed, base bisinuate, disc moderately convex, median 

 line feebly impressed ; surftice densely scaly, median line and sides paler. 

 Elytra densely scaly and with twelve rows of moderate punctures, the 

 ninth somewhat confused, intervals indistinctly biseriately punctulate. 

 Body beneath densely scaly, scales larger and paler than above. Legs 

 densely scaly, tibiae with short hairs on the inner side. Length .40 inch ; 

 10 mm. 



Occurs in Floilda, and is not rare. 



The base of the elytra is not only bisinuate, but there is also a small 

 dentiform prominence contiguous to the thoracic hind angles. Lacordairc 

 mentions this character for two Cuban species, but not for our own. 



P. distans, n. sp. 



Form elongate oval, densely covered with pale bluish white scales, with 

 faint cupreous lustre. Head and rostrum slightly longer than the thorax, 

 densely scaly. Rostrum with a fine median elevated line, ending in a 

 frontal puncture. Thorax broader than long, slightly naiTower in front, 

 sides feebly arcuate, base feebly bisinuate, disc moderately convex, with 

 large, deep punctures irregularly placed, densely scaly. Scutellum oval, 

 truncate at base. Elyti'a oblong, sides feebly arcuate, base very feebly 

 bisinuate, humeri not dentiform in front, convex, densely scaly and with 

 twelve rows of coarse and moderately deep punctures, intervals flat, with 

 a single row of minute punctures, each bearing a longer scale. Body 

 beneath and legs densely scaly, and with minute scale-like hairs. Length 

 .32 inch ; 8 mm. 



Notwithstanding the foct that the elytra are not prominent at the middle 

 of the base of each, I am unwilling to separate this species under a distinct 

 generic name. In the generic table of the Tanymecides, Lacordaire assigns 

 strongly cavernous corbels to Pachnceug. This is not so in either of our 

 species, the posterior tibiae having at their tips merely the double row of 

 bristles very feebly separated. The form of the eyes appears to be a 

 character of greater value in the arrangement of the genera of this group, 

 after the form of the tarsi, than any that is made use of by Lacordaire. 

 Too much importance seems to have been given to the form of the base of 

 the elytra, and it will be found that exceptions are met with frequently in 

 many genera. 



The species above described was collected at Cedar Keys and Capron, 

 Florida, by Messrs. Schwartz and Hubbard.
