more shining, with sulcus of the thorax much dilated ante- 

 riorly. 



In Proc. Zool. Soc, 1901, Mr. Jacoby describes C. hisu- 

 laris from Haiti. He had previously used this name for a 

 Central American form, Biolog., p. 78. So for the former 

 I would suggest the name haitiensis. 



C. boliviana Jac. has at the rear of the thorax on the crest 

 of the declivity four obsolete tubercles, in a semicircle, 

 analagous to deyrollei Jac. or kermes Lac. The rear of the 

 thorax is obsoletely toothed, approaching amazonica Jac. 

 and humeralis Bow. A form which at present I regard as a 

 variety of boliviayia, occurs in which the elytra have a nar- 

 row, transverse yellow fascia from shoulder to shoulder, the 

 front edge of the fascia just taking in the scutel. This 

 variety is from Cochahamba, Bolivia. 



The types of all the new species described in this paper 



are in my collection. 



Pseiidochlamys ? rufescens nov. sp. Rufous, with here and there 

 darker clouds. Head very large, flat, with great mandibles, thorax 

 very thickly and finely punctured, with a rounded hump, median sul- 

 cus very faint but discernible behind, where it is bordered by two dark 

 clouds after the manner of many Chlamys, suture smooth, prosternum 

 wide, very abruptly narrowed, at about the anterior third, remaining 

 two-thirds a little less narrow and parallel ; length 4f mm.

My only example of P. megalostomoides Lac. is a 9 , so I 

 have no opportunity to compare the characteristics of the 

 cf, but the epistome of rufescens seems hardly sufficiently ex- 

 cavated to bring it into this genus, the excavation is smooth 

 and slightly concave, not "cavernous," the margins slightly 

 thickened and the angles prolonged, the scape of the an- 

 tennae is much thickened at the end and somewhat angularly 

 prolonged inward. The hump of the thorax is very large at 

 its base and occupies nearly the whole width of the thorax. 

 The elytra show faint elevated lines in the usual places, 

 with faint connections and tubercles here and there, the most 

 prominent of the former is ante-median, a little to the side. 

 There is a very moderate tubercle at the middle of the base,
