382 PHYTOPHAGA. 



3. Acrocyum maculicollis. (Tab. XXII. fig. 24.) 



Pieeous below; above flavous ; head with one, thorax with nine, black spots; elytra finely and closely 

 punctured, the suture fulvous, with two greenish-black markings, the disc with seven or eight small spots 

 of the same colour. 



Length 3 lines. 



Head impunctate, a spot on the vertex, the inner margin of the eyes, and the frontal tubercles black; the 

 labrum and the apical joint of the palpi pieeous ; antennae half the length of the body, black, the basal 

 joints flavous at the base, gradually increasing in length from the second to the fourth joint ; thorax 

 scarcely more than twice as broad as long, the sides straight, the anterior angles acute but scarcely pro- 

 duced, the surface impunctate with a small but deep fovea on each side, flavous, with two rows of black 

 spots, placed transversely, the first row consisting of four, the second row of five spots which occupy the 

 intervening spaces between the first row ; scutellum fulvous ; elytra wider at the base than the thorax, 

 very closely and finely punctured, the sutural and lateral margins narrowly fulvous, the former with an 

 irregular short transverse band before and a spot at the middle, greenish-black ; of the other spots, two aire 

 placed at the basal margin, one below the latter at the sides, three very small ones at the middle across 

 the disc, two others (larger, the posterior one V-shaped near the apex), and a very small spot at the apical 

 angle ; underside pieeous, the upper part of the breast and a spot at the sides of the metasternum flavous ; 

 legs spotted with flavous and pieeous. 



Rah. Mexico, Jalapa (Edge). A single specimen. 



4. Acrocyum tarsata. 



Flavous ; head and thorax impunctate ; elytra finely and closely punctured, with regular rows of deeper punc- 

 tures, testaceous ; three spots at the base and three below the middle, placed transversely, pieeous. 



Length 3 lines. 



Head without distinct frontal tubercles, impunctate ; antennas slender, two thirds the length of the body, the 

 third joint nearly twice the length of the second, their colour entirely dark fulvous ; thorax twice as 

 broad as long, rather depressed above, impunctate, the sides evenly rounded, the anterior angles slightly 

 produced outwards, the posterior margin somewhat sinuate, on the surface of a pale flavous colour, with a 

 small pieeous spot at each side at the middle of the extreme lateral margin ; elytra extremely closely 

 punctured, with single and some double rows of more strongly impressed punctures; at the extreme 

 base three small pieeous spots are placed transversely (the one near the scutellum very obscure), three 

 others below the middle are larger, and the sutural one is of an elongate shape ; underside and legs darker 

 fulvous ; the first joint of the posterior tarsi is as long as the three following joints united ; the first joint 

 of the anterior tarsi is greatly dilated ; the base of the mesosternum emarginate ; the anterior coxal 

 cavities closed. 



Rah. Guatemala, Yzabal (Salle). 



This species, of which a single specimen only is before me, differs from the three 

 others described here by the elongate joint of the posterior tarsi and by the different 

 punctuation of the elytra. I have placed the species in this genus, as it has the other 

 structural characters in common with it. 



NOTOZONA. 



Notozona, Clark, Journ. of Entom. ii. p. 409 (Nov. 1865). 



The handsome and large species which form the genus Notozona have for the most 

 part been described by Clark and Mr. Baly, while the genus itself requires, in my 

 opinion, further investigation and better definition. I find, for example, that the palpi 

 in Notozona are described as robust and claviform by Chapuis, who separates on that
