HYDNOCERA. 171 
punctiform impression ; centre of the disk almost smooth; sometimes the head and 
thorax have a faint brassy tinge. Elytra steel-blue, shining; very distinctly, rather 
sparingly punctured, more finely and more closely so before the apex, in which part 
some shining grey hairs are clearly visible; they cover three quarters of the body’s 
length. The legs vary somewhat in colour, the Mexican examples having the femora 
almost wholly yellow. In two specimens from Calderas the elytra want the yellow 
basal spot. This species is rather nearly allied to H. flavifemorata, Gorh. (Trans. Ent. 
Soc. 1877, p. 261), but will be distinguished by the absence of the pale fascia, as well 
as by the shorter elytra with smooth elevated apices. 
9. Hydnocera pulchella. 
Nigro-subceerulescens, femoribus basi flavis; elytris macula subhumerali fasciaque pone medium, interrupta 
cinereo-pubescente, testaceis. Long. 6 millim. ¢. 
Hab, Panama, Volcan de Chiriqui (Champion). 
Var.? Ore, antennis, pedibus, elytrorum humeris maculaque postica parva testaceis. 
Hab. GuateMaua, San Gerénimo ; Panama, Volcan de Chiriqui (Champion). 
Resembles the preceding species a little; but the elytra are not shortened nor tumid 
at the apex, but almost cover the abdomen, and are punctured at the apex. The head 
and thorax are both very thickly punctured ; and hence the latter appears more opaque. 
_ The antenne and legs are darker in the typical specimens; and the pale basal spot is 
not on the base, but below the shoulder, between it and the suture. The elytra are of 
a fine dark steel-blue, less narrowed behind than in H. chalybeata, and reach nearly as 
far back as the hind femora do, whereas in such species as have shortened elytra they 
scarcely reach beyond one third of the femora. 
10. Hydnocera nitidicollis. (Tab. IX. fig. 9.) 
Hydnocera nitidicollis, Chevr. Rev. et Mag. Zool. 1874, p. 71°. 
Hab. Mexico (coll. Gorham), Puebla! (coll. Sallé). 
The elytra are greenish, with an anterior fasciate patch formed of white hairs, and 
another fascia behind the middle white, clothed also with white pubescence. ‘The 
head and thorax coppery. 
Apparently rare ; there are only two specimens in Sallé’s and one in my own collection. 
11. Hydnocera trichroa, (Tab. IX. fig. 5.) 
Brevis, oblonga, nigro-subsnescens, omnino crebre subtilissime punctata; ore, antennis, pedibus basi, tarsis 
anticis humerisque late rufis; elytris medio albo-fasciatis. Long. 4-53 millim. 
Hab. Guatemana, Duefias, San Gerénimo (Champion). 
Head and thorax obscurely greenish black, very closely punctured, opaque ; anterior 
constriction of the latter but faintly impressed. LElytra rather parallel, covering the
