CEEPIDODERA. 343 



The colour of the legs and antennae separates this from those in other respects 

 similarly coloured species, notably C. brasiliensis, Baly, which latter has the legs and 

 basal joints of the antennae fulvous ; the thorax in that species is also more transverse, 

 and the frontal tubercles are nearly absent. A single specimen, amongst seventeen 

 others, has the legs fulvous as well as the first joint of the antennae. In other respects 

 it is entirely similar. 



2. Crepidodera semihirsuta. 



Below black ; head, antennas, thorax, and legs fulvous ; elytra metallic greenish blue, strongly punctate- 

 striate. 



Length 1 line. 



Head impunctate ; frontal tubercles distinct, rather broad, limited behind by an oblique groove ; antennae half 

 the length of the body, the terminal joints thickened, the second joint nearly as long and as thick as the 

 basal one, third and fourth joints equal ; thorax transverse, the sides nearly straight, slightly rounded 

 before the middle, basilar groove deep, slightly sinuate, and extending nearly to, and well denned at, the 

 sides, surface smooth and impunctate ; elytra subcylindrical, metallic greenish blue, strongly punctate- 

 striate, the interstices sparsely furnished with single fulvous hairs, shoulders prominent. 



Hab. Guatemala, Capetillo (Champion). 



Although the coloration of C. semihirsuta is not unfrequently found in others 

 belonging to the present genus, I am unable to refer it to any of the described species 

 on account of the small size and the sparse but distinct pubescence of its elytra. With 

 the genus Epitrix this species has the pubescence in common although to a less extent; 

 but the thorax is that of a true Crepidodera, the posterior margin being but slightly 

 advanced in the middle, and the anterior angles not oblique as in the allied genus. 



3. Crepidodera guatemalensis. 



Below black; legs and antenna fulvous ; above brownish aeneous; thorax coarsely punctured ; elytra strongly 

 punctate - striate . 



Length f-1 line. 



Head impunctate ; frontal tubercles forming oblique narrow ridges ; antennae robust, half the length of the 



body, fulvous, third and fourth joints equal; thorax transversely subquadrate ; basilar sulcation deep and 



bounded by an equally deep rectangular lateral groove, surface strongly and rather closely punctured ; 



elytra slightly depressed below the base, strongly, closely, and regularly punctate-striate ; metatarsus as 



long as the two following joints together ; legs fulvous. 



Eab. Guatemala, Capetillo, Dueiias (Champion). 



This small species well represents the typical form of Crepidodera, with which it 

 agrees in all structural characters ; in colour it may be compared to C. elegantula, 

 Baly, or even to the European C. helxines ; from these and other species it is princi- 

 pally distinguished by the coarsely punctured thorax in connexion with its small size. 



4. Crepidodera pallipes. 



Below black • above metallic greenish ameous ; antennae and legs testaceous ; thorax impunctate, the transverse 



groove indistinct in the middle ; elytra with the base strongly raised, distinctly punctate-striate. 

 Length 1 line.
