those previously mentioned. In fact, it is quite evident that a divi- 

 sion of Ichnea along the lines proposed by Gorham in the Biologia 

 Centrali-Americana is necessary. Eleven specimens of this species 

 were taken, seven at Tumupasa and two each at Yvon and Cachuela 

 Esperanza. There is considerable variation in size, the smallest and 

 largest specimens, both from Tumupasa, measuring, respectively, 

 6 mm. and 10.5 mm. There is also a very interesting color variation 

 displayed. All of the specimens from Tumupasa have antennae 

 which are entirely black, and of these, four have the tarsi entirely 

 black. The remaining three specimens from Tumupasa have the 

 third to fifth tarsal segments pale. The Yvon and Cachuela speci- 

 mens are similar to these last mentioned in tarsal coloration but all 

 have the apical half of the terminal segment of the antenna pale. 

 This last color phase is as described in the original reference to the 

 species. There is also some variation in the extent of the pale color- 

 ation on the under side. 



Subfamily Enopliinae. 



Genus CREGYA LeConte, 1861. (GALERUCLERUS Gahan, 1910) 



20. CREGYA POSTICALIS, new species 



Shining brownish-black; head except occiput, flanks of prothorax, 

 extreme apices of elytra, femora and basal halves of tibiae pale. 

 Head finely but not densely punctured, sparsely pubescent, occipital 

 spot extending forward onto the vertex, antennae ten-segmented, 

 dark except for the first segment which is pale beneath. Pronotum 

 slightly longer than broad (25-24), sharply dilated at the sides just 

 behind the middle, surface polished; on disk the punctation is very 

 fine and sparse, on the flanks coarse and moderately dense. Flanks 

 narrowly behind, more broadly in front, pale testaceous; disk nar- 

 rowly in front, behind including the entire base, brownish-black. 

 Elytra coarsely punctured on the basal two-thirds, very finely punc- 

 tulate on apical third; the coarse punctures are in rows on disk, 

 they are confused on the flanks. Vestiture sparse and erect, pale. 

 The underpart of the pro- and meso-thoraces pale, metathorax dark, 

 abdomen castaneous. Legs pale, anterior femora with dark spot at 

 apices, anterior tibiae dark externally, middle tibiae dark at apices, all 

 tarsi dark. Length: 5 mm. Locality: Kurrenabaque. 



Type.—Csit. No. 29362, U.S.N.M. 



Nearest allied to C. jrontale (Kuwert) from which it difTers in the 

 arrangement of the dark and light areas.
