298 PHYTOPHAGA. 



Ha b. Guatemala, Quiche Mountains (Champion). 



From the species described possessing elytral costse, the present one is separated by 

 its smaller, elongate, and parallel shape, the cupreous colour, and finely granulate 

 upper surface, as well as by the fine and rather even punctuation of the thorax. Ten 

 specimens were obtained by beating a species of Alnus. 



9. Haltica brevis. (Tab. XVII. fig. 19.) 



Haitica brevis, Harold, Coleopt. Hefte, 1875, xiv. p. 25 l . 



Hah. Panama, Bugaba (Champion). — Colombia 1 . 



The two specimens obtained at Panama agree so perfectly with von Harold's descrip- 

 tion that I must refer them to the above species. The short, convex, subrotundate 

 shape prevents the insect from being confounded with most of the allied species, the 

 nearest of which seems to be H. facialis, Baly, which differs, however, from the present 

 in the scarcely visibly punctured elytra and the much less transverse thorax. The 

 Panama specimens are a little smaller than the size given by its describer, but agree in 

 all other respects. 



10. Haltica flavicollis. 



Elongate, parallel; below black; head, thorax, basal joints of antenna, and the legs flavous; elytra dark 

 violaceous, closely punctured. 



Head t^ito^d rather swollen; frontal tubercles strongly raised and triangular ; carina extremely short ; 

 antenna more than half the length of the body, all the joints, with the exception of the second one, 

 elongate, the third and fourth of equal length, the two basal joints flavous, the rest fuscous pubescent j 

 thorax transversely convex, the sides distinctly narrowed at the base and widened at the middle, anterior 

 angles tuberculoma ; the basal groove deep and continuing upwards at the sides the space anteriorly 

 and posteriorly of this groove impunctate and much swollen ; scutellum flavous ; elytra parallel, ^violaceous 

 blue, rather finely but very closely punctured, with a few shallow and indistinct longitudinal depressions 

 near the sides ; space below the base not depressed ; elytral epipleur* broad, continuing to the apex, their 

 surface transversely wrinkled; legs flavous, the posterior femora strongly incrassate, the tibia simple; 

 last abdominal segment of the male with a very deep longitudinal excavation of flavous colour, that of the 

 female simple. 



Eab. Mexico (coll. Jacoby), Cuernavaca (Salle). 



In several respects this species differs from others of the genus ; the coloration, 

 simple tibiae, and more strongly incrassate posterior femora are not generally found in 

 Haltica. The deep longitudinal excavation to be seen in the last abdominal segment 

 in one of the specimens, which I consider the male, is another peculiarity. The species 

 has nevertheless the general " habit " of a true Haltica, and the thoracic groove is also 

 exactly similar to those of the allied species. I only know of two specimens, the one 

 contained in my own, the other in the collection of M. Salle.
