AnCISTRTA TARSALIS, Sp. 11. 



Elonr/atn, cyUndrica, ni//ra, nit Ida ; capite ufrinqice evident ei- pnnc- 

 tato, pmictis elongatis ohliquis ; tliorace sat crehre evidenter punctata ; 

 elytris apice retiiso ; tarsorum anteriorum articido primo gracili, tibia 

 Jongiori. ■ Long. 4i lin., J at. I Jin. 



Closely resembles A. retiisa, but is mneh longer and narrower. The punctures 

 at the side of the head above the eye are elongate, oblique, and almost confluent. 

 The thorax is relatively longer and the punctuation rather less strong, moderately 

 close. The apex of the elytra is hollowed out in the same manner, but the apex of 

 each elytron is somewhat acuminate. The basal joint of the antei-ior tibiae is re- 

 markably long and slender, longer than the tibia, about equal iu length to the 

 following joints taken together.

HEMIPEPLUS, Latr. (1825), 1829. 

 Ochrosanis DoJirni, Pascoe, 18G6, = liemipterus, Dej., MS. 



The type of Uemipeplus is now in Mr. Janson's collection, I have 

 carefully examined it, and am convinced that the shortness of the 

 elytra is only accidental ; it agrees in all other respects vpith a specimen 

 in the British Museum, which I have determined to be Ochrosanis 

 Dohrni, Pascoe. Length 4<^ lin. The Museum example measures 

 barely 4 lines, but it agrees perfectly with Mr. Pascoe's figure and 

 description. 



Dr. Le Conte suggests (Proc. Ac. Phil., 1873, p. 328) that Och- 

 rosanis Dohrni is his Uemipeplus marginipennis (which only measures 

 Tsinch). The form of the thorax is, however, quite different in the 

 two insects. 



Hemipeplus (Nemtcelus) marginipennis, Dej, 

 The Dejeaniau specimen of this species is now in Mr. Janson's 

 collection. The following diagnosis is drawn up from a specimen in 

 the National collection, agreeing perfectly with Dejean's. 



Valde elonqatus et depressus, parallelus, testaceus, nitidus ; capite 

 cum oculis tliorace patdo lutiori, pone oculos subito angustato ; thorace 

 latitudine \ longiori, lateribus antice rotundatis, piostice siib-siimatis, 

 pone mediutn angustato, fovea utrinque prope basin impresso ; elytris 

 punctulatis, margine laterali infuscato. Long. 3 lin. 



Hab. : Florida. 



My object in describing this is, that I believe it to be quite distinct 

 from the species described under the same name by Dr. Le Conte, 

 which he says is two-tenths of an inch in length, and of which there
