STUDIES IN THE AMERICAN BUPRESTID^ 87 



as in campestris, the sexual characters of the under surface nearly sim- 

 lar. Length (d^, 9) 25.0-30.0 mm.; width 8.5-10.8 mm. Texas. 



bisinuata n. sp. 



Form broader and less parallel than in caw^g.y/m, the size larger, the pronotal 

 sulcus broader and more shallow, visible for only three-fourths of the 

 length and having a slightly flattened elevation near the anterior mar- 

 gin; prothorax more " triangular, " the elytra more dilated. Louisiana 

 (near New Orleans). [ = Chalcophora langeri Chev.]. . langeri Chev. 



The species langeri Chev., is of rather uncertain tenure; the few 

 lines of description given above are drawn from information furnished 

 LeConte by Chevrolat himself and printed in the Monograph of the 

 former author. It apparently cannot be the species described above 

 under the name bisinuata, neither does it seem to be the fulleri of 

 Horn. The description of the prothorax as triangular is rather indef- 

 inite, fitting campestris better than any other, but the characterization 

 of the thoracic sulcus will not at all apply to that species.^ I have 

 therefore appended it provisionally as above and until further material 

 from Louisiana can be collected, for as yet we certainly do not know 

 all concerning the fauna of that section of the country. There are 

 probably a number of species of Texania in Texas and territory 

 immediately adjacent, which region appears to be its proper centre 

 of dispersal. All the species of Texania seem to be more or less rare 

 in collections. 



Buprestis Linn. 



Ancylocheira Esch.; Anoplis Kirby. 

 The species of this genus are properly holarctic in range, some trop- 

 ical and Australian forms now attached belonging in reality to other 

 genera; they are numerous and troublesome to separate with certitude, 

 because of considerable variation in form, size and sculpture within 

 specific limits; many of them also are rare or local. It is possible, 

 however, by careful study of large series, to become sufl&ciently fam- 

 iliar with the laws of intraspecific variation, to be tolerably sure in 



' Such evidence as we have shows beyond doubt that langeri is a species 

 of the fulleri type, and that the probability is that the expression "prothorax 

 more triangular" refers to the very patent fact that the sides of the prothorax 

 are more angulate than in campestris. It may be therefore that either 

 fuller* or bisinuata is a synonym of langeri. Or perhaps both fulleri, which 

 I have not seen, and bisinuata may prove to be varietal forms or synonyms 

 of langeri.
