Hob. Beitish Hondukas, Belize (Blancaneaux). 



This is a slightly broader species than L. parvula, with the thorax more obliquely 

 narrowed in front, the elytra shorter and a little less acuminate at the apex. The head 

 is rather more deeply sulcate, with the reticulate striolation very delicate and scarcely 

 distinguishable in parts even under the microscope ; there are four or five large shallow 

 punctures in a line on each side. The thorax is broader, almost smooth, very slightly 

 sinuate at the sides about the middle, sparingly punctured ; the punctures small but 

 distinct, more distinct than in L. parvula. The elytra are moderately strongly punc- 

 tured in lines, with the intervals only slightly less strongly punctured. 



A second specimen has the elytra obscure dark green. 



20. Leiopleura polita. (Tab. IX. fig. 8.) 



Convexa, nitidissima, subtus nigra ; capite thoraceque lsete cupreis, punctatis ; scutello brunneo-cupreo ; elytris 



viridi-cyaneis, striato-punctatis.

Bab. Panama, Bugaba (Champion). 



The head is finely rugose, with rather large shallow punctures placed not very close 

 together. The thorax is finely reticulate-striolate, slightly rugose at the sides ; punc- 

 tured, the punctures small but very distinct, not very close together. The scutellum 

 is brown. The elytra are dark bluish-green, finely striate-punctate, with finer punc- 

 tures scattered over the surface. The apex of the abdomen in the male is furnished 

 with about twelve teeth, those in the middle are long and gradually acuminate, one 

 or two at each end being smaller ; the two sides are not quite alike in the specimen 

 described. 



21. Leiopleura longula, 



Elongata, convexa, polita, supra cyanea, pUrpurascens : thorace parce punctato, linea mediana vireacente ; 



scutello virescente ; elytris obscure punctulatis.

Had. Mexico, Cordova (Salle). 



This is a much more elongate species than L. polita, with the thorax not quite so 

 obliquely narrowed in front. The elytra are much longer, a little narrowed below the 

 shoulders, a little broader at the posterior two-thirds than at the base, and then gradu- 

 ally narrowed to the apex. The head is rather deeply longitudinally impressed in the 

 middle, finely and very closely reticulate-striolate, with a few small punctures. The
