DISONTCHA. 317 



the many similarly coloured species of this genus can only be separated by finely 

 marked but good (if constant) characters, I must consider the present species as un- 

 described. From Zapote only a single specimen was obtained, which scarcely differs 

 from the Mexican forms. On account of the uneven almost subtuberculate surface of 

 the thorax, the species ought certainly to be separated from D. alternata. 



28. Disonycha brunneofasciata. 



Testaceous below ; antennas black, the first joint fulvous ; thorax spotted with fulvous ; elytra scarcely visibly 

 punctured, testaceous, a broad Butural and discoidal as well as a narrow lateral band dark fulvous, 

 margined with fuscous. 



Length 3 lines. 



Hab. British Honduras, river Hondo (Blancaneaux). 



In the elytral pattern and general shape, this species resembles D. glabrata ; from 

 this and all other species the colour of the elytral bands at once distinguishes it. These 

 bands themselves are broad, often broader than the intervening lighter portion, with the 

 exception of the lateral band, which is extremely narrow; their colour is a dark fulvous 

 often margined with piceous ; the antennae have the third and fourth joints of equal 

 length ; the thorax has generally a triangular-shaped central and two lateral fulvous 

 spots ; the apex of the tibia? and the tarsi are piceous. The ten specimens obtained 

 do not differ in any way, and must therefore be considered specifically distinct. 



29. Disonycha brevilineata. (Tab. XVIII. fig. 23.) 



Ovate testaceous ; antenna and tarsi black; elytra distinctly and closely punctured, a thin longitudinal stripe 

 at the disk from base to apex, another at the lateral margins, and a very short stripe near the apex 

 black. 



He^d with afew punctures between the eyes ; antennae scarcely half the length of the body ; the first three 

 ioints testaceous below ; fourth joint much longer than the preceding ; thorax more than twice as broad as 

 long widened at the middle, the anterior margin straight, the posterior one nearly semicircular, posterior 

 angles oblique- surface impunctate, basilar sulcation absent ; scutellum black ; elytra finely, closely, and 

 distinctly punctured, testaceous, as well as their epipleurse; each elytron with a narrow black stripe from 

 the middle of the base to a little distance from the apex, and another parallel and close to the lateral 

 margin ; between these two Hues a short stripe is placed near the apex, and terminates at the same distance 

 as the other stripes ; entire underside and legs testaceous ; tarsi black. 



Hab. Mexico, Capulalpam (coll. Salle). 



The single specimen before me is easy to recognize on account of the elytral markings. 



30. Disonycha abbreviate (Tab. XIX. fig. 3.) 



Disonycha abbreviates, Melsh. Proc. Ac. Phil. iii. p. 163 \ 



Hab. North America.— Mexico, Tehuantepec (coll. Salle).— Guatemala (coll Salle). 



The Mexican and Guatemalan specimens before me show no perceptible difference 

 from others contained in my collection from North America, which agree perfectly with
