492 REVISION OF THE ELATERID.E 



dorsali obsoleta loevi, basi ad medium acute tuberculata, elytris postice acutis, dense punctulatis, striis 

 tenuibus punctulatis. Long. - 85 — 1 - 10. 



This species was discovered by Mr. A. Salle near New Orleans, and kindly given me 

 by Mr. Gue.v. It agrees so closely with the descriptions and figures of A. fuscipes Fair., 

 that I supposed it to be that species, imported accidentally from the East Indies. Re- 

 cently, however, Mr. Schott, of the Mexican Boundary Commission, has found it in abun- 

 dance on the lower Rio Grande, at Eagle Pass. Between the punctures of the'elytra may 

 be perceived small transverse rugosities: the smooth dorsal line of the thorax is very in- 

 distinct, and is visible only near the base; the basal tubercle is large and almost reclivate.

 sum angustato, convexo, lateribus rotundatis, angulis posticis subdivergentibus, carina elongata sub- 

 tili margini parallela, confertim punctato, linea dorsali indistincta lsevi, basi ad medium tuberculata, 

 elytris postice acutis, dense punctulatis, striis subtiliter punctatis. Long. 1/07. 



I have named this fine species after Mr. Schott, as a slight tribute to the scientific zeal 

 displayed while attached to the Boundary Commission under Majors Graham and Emory; 

 a single specimen was procured on the lower Rio Grande. The sculpture is as in the 

 preceding, from which this species differs in the form of the thorax. It exactly resembles 

 in appearance the Egyptian A. notodonta Latr. 



Pyrophorus Illigcr.

For a specimen found in Louisiana, I am indebted to Mr. Guex. The little tubercle of 

 the middle of the base of the thorax is quite prominent. 



Aphanobius Esch. (emend.) 



This genus should be restricted to those species having the last joint of the antenna? 

 deeply constricted, the front slightly concave and not margined in front; the mesosternum 

 prominent; the plates of the posterior coxce somewhat suddenly slightly dilated, and emar- 

 ginate posteriorly, and the internal tooth sharp, and moderately large: the tarsi are some- 

 what inflated beneath, and very densely pubescent, (being in this respect precisely as in 

 Agrypnus fuscipes.) The first joint of the antenna} is moderately elongated, the second 

 and third small, the fourth and following strongly triangular, and equal: the suture of the 

 prosternum is bent outwards posteriorly, and is very deeply marked: the first joint of the 

 tarsi is hardly as long as the second and third united: the base of the thorax has a slight 

 elevation in front of the scutellum, but it is by no means obvious: the posterior angles 

 have a short carina: there arc no apparent basal fissures.
