3 Tl'icliobaris insolita n. sp. — Oblong-oval, somewhat robust and 

 distinctly depressed, black tlnougliout, the integuments polished when de- 

 nuded but densely clothed with large broad recumbent whitish scales. Head 

 polished, glabrous, minutely, sparsely and obsoletely punctate, the transverse 

 impression strong and normal ; beak only moderately robust, evenly, rather 

 strongly arcuate, abruptly very strongly bent at base at the junction with the 

 head, deeply punctate, squamose especially at tlie sides, fully as long as the 

 prothorax in the female ; antenufe rather slender, the scape but slightly 

 shorter than the funicle, the second joint of the latter much longer than wide 

 and one-half longer than the third which is quadrate, fourth a little wider 

 than long, outer joints but slightly thicker, the club small but longer than 

 wide and rather abrupt, conoidal, densely clothed with robust recumbent 

 cinereous squamules, tlie basal joint constituting a little less than one-half 

 the mass. Prothorax short, about one half wider than long, the sides sub- 

 parallel or very feebly convergent and nearly straight to apical third, then 

 broadly i-ounded and moderately convergent but scarcely at all constricted to 

 the apex, which is fully one-half as wide as the base, transversely truncate ; 

 base broadly bisinuate ; disk with a narrow entire cariniform impunctate line, 

 the punctures round, deep, perforate moderately large and mutually quite 

 distinctly separated. Scutellum well developed, transverse, broadly im- 

 pressed, the sides acute, prominent, slightly flexed posteriorly and corniform. 

 Elytra two-fifths longer than wide, one-fourth wider than the prothorax and 

 nearly two and one-half times as long as the latter ; sides subparallel and 

 straight, tlie humeri scarcely prominent, the apex broadly rounded and sub- 

 truncate, each elytron strongly callous in the middle at apical fourth ; striae 

 rather fine but deep and abrupt, the intervals flat, three times as wide as the 

 grooves, rather finely confusedly and moderately closely punctate when de- 

 nuded. Prosternum "feebly impressed, the coxae separated by nearly one-half 

 their width. Legs moderate ; tarsal claws short, connate for one-half their 

 length, parallel, slightly everted toward apex and quite distinctly unequal in 

 length. Length 4.2 mm. ; width 1.8 mm. 



Florida. 



A single female example collected in the extreme southern part 

 of the State by Mr. Francis Kinzel, and kindly given to me by 

 Mr. Jiilich. It is somewhat intermediate between the texana and 

 trinotata groups of the genus, but is widely distinct from any other 

 species. The scales are shorter broader and larger than in any other 

 form known to me, not even excepting cylindrica, some of those 

 on the under surface of the prosternum being only slightly longer 

 than wide. The median parts of the third and fourth ventral seg- 

 ments are abruptly glabrous, the normal scales being replaced toward 

 the apex of each by very minute slender squamules sparsely dis- 

 tributed.
