HALTICA. 299 



11. Haltica parvula. (Tab. xvn. fig. 16.) 



Ovate, convex; below black; first four joints of the antennae, head, thorax, and four anterior femora fulvous ; 

 elytra blackish blue, very finely semipunctate-striate. 



Var. Legs entirely black. 



Length 1| line. 



Head impunctate ; frontal tubercles in shape of a transverse oblique ridge ; carina short and acutely raised ; 

 antennae quite half the length of the body, black, the four basal joints fulvous ; first joint rather slender 

 and curved, second and third joints of equal length, the terminal joints more elongate and slightly thick- 

 ened, thorax only slightly broader than long, rather strongly convex, the sides nearly straight, deflexed 

 anteriorly, the angles not produced ; surface in front and behind the basilar sulcation entirely impunctate, 

 the latter deep, slightly curved and limited at the sides by a very short longitudinal fovea or groove, 

 beyond which the sulcation is extending upwards near the lateral margin ; scutellum black ; elytra convex, 

 without any basal depression, extremely finely and closely punctured, the punctuation arranged indistinctly 

 in lines, the extreme apex nearly impunctate ; underside and legs, with the exception of the four anterior 

 femora, black. 



Hob. Guatemala, San Juan in Vera Paz (Champion) ; Panama, Volcan de Chiriqui 

 (Champion). 



This is evidently another of those small species deviating from Haltica somewhat by 

 the shape of the thoracic groove, of which several others, similarly structured, have 

 been described by von Harold in his ' Coleopterologische Hefte.' H. parvula seems 

 very closely allied to H Iwviuscula, Har. ; but as all the specimens, to the number of 

 ten, differ in the colour of the legs, which von Harold describes as red (with the 

 exception of the posterior femora), and in the shape of the frontal tubercles, as well 

 as in the want of an elytral elevation at the base, I must consider this species a 

 different one. 



12. Haltica minuta. (Tab. xvn. fig. 17.) 



Oblong, convex; antenn&e, underside, and legs black; above bluish green; thorax long; elytra without basal 

 elevation, distinctly punctured. 



Length 1 line. . . 



Head impunctate; frontal tubercles in shape of two transversely oblique narrow ridges; carina acutely raised, 

 widened in front ; clvpeus bounded above by an oblique very deep and somewhat sinuate groove; antennae 

 half the length of the body, the first joint slender, elongate, second scarcely shorter than the third and 

 following joints ; thorax nearly as long as broad, surface very convex and swollen, the lateral margin 

 nearly straight and only slightly rounded near the anterior angles ; basilar groove deeply impressed, 

 limited at each side by a small but distinct fovea and continued beyond the latter upwards; space below 

 the groove, like the rest of the surface, entirely impunctate ; elytra without any trace of a basal depression, 

 more or less distinctly and closely punctured, the punctuation arranged in rather regular lines. 



Hah. Mexico, Jalapa (Hoge); Panama, Volcan de Chiriqui (Champion). 



This is one of the smallest species with which I am acquainted, and seems to form 

 one of the group described by von Harold, in which the thoracic groove has a longi- 

 tudinal fovea at each side, beyond which the former is continued. The present species 

 seems closely allied to H. innuba, Har., but is smaller, and further distinguished by the 

 deep groove at each side above the clypeus, and by the entire want of a basilar elytral 

 elevation A single specimen from the same locality differs from the description given
