8. Disonycha dorsata. (Tab. XVIII. fig. 11.) 



Disonycha dorsata, Harold, Deutsche ent. Zeitsch. xxiv. 1880, p. 220 \ 



Hab. Mexico \ Jalapa, Cordova {Edge), Tuxtla, Playa Vicente, Cosamaloapam {coll. 

 Salle); British Honduras, river Hondo (Blanedneaux) ; Guatemala, Paraiso,La Tinta, 

 Teleman (Champion). 



Allied to D. discoidea in regard to coloration ; the elytra may be described as black, 

 with a narrow, but very regularly shaped, yellow submarginal band, which extends from 

 the base to the sutural margin at the apex ; constant in this species seems to be the 

 black elytral epipleurse, and a more or less distinct, small, central thoracic piceous spot 



or line. 



In the specimen obtained by Mr. Champion at Paraiso, the apex of the femora as 

 well as that of the tibia? are black, and the vertex of the head has a small spot of the 

 same colour ; several other specimens obtained in Vera Paz differ again in the colour 

 of the lateral elytral margin as well as in that of their epipleurse, being dark fulvous 

 instead of black ; in other respects, however, I cannot find any difference of importance. 



9. Disonycha sallaei. (Tab. XVIII. fig. 12.) 



Head, breast, and middle of abdomen black; basal joints of antennae, tborax, and legs flavous ; elytra closely 

 punctured, black, a submarginal band, widened at the apex, flavous. 



Length 3 lines. . 



Head black, with a few deep punctures round the eyes, transversely grooved between the latter, the frontal 

 tubercles distinct ; carina strongly raised ; labrum margined with testaceous ; antennas with the fourth 

 joint much longer than the third, flavous, the four terminal joints fuscous; lateral margin of the thorax 

 rounded, and widened below the middle ; posterior margin distinctly produced at the middle, obliquely cut 

 at the angles; elytra closely and distinctly punctured; the disk and the epipleurse as well as the lateral 

 margin black ; this colour is abbreviated at some distanee from the apex, the latter and a narrow band near 

 the margin, commencing at the shoulder, flavous; legs, tarsi, and sides of the abdomen flavous. 



Hob. Mexico, Cordova (Salle, Edge). 



This is a very distinct species on account of the flavous antennae, the black head, and 

 similarly coloured elytra, interrupted by the flavous band ; this latter the species has in 

 common with D. dorsata and several others, but in the present the black margin as 

 well as the disk of the elytra is abbreviated before the apex. I find the species in the 

 collection of Mr. Baly under the above name as described by this author, but I am 

 unable to find any published description. 



10. Disonycha pallidicornis. (Tab. XVIII. fig. 17.) 



Below obscure piceous; antennae and legs flavous ; head and thorax fulvous ; elytra black, a transverse narrow 

 basal band, another at the middle, and a third near the apex yellow ; posterior femora piceous. 



Length 2 lines. 



Head impunctate, with a more or less distinctly longitudinal depression at the vertex ; frontal tubercles 

 extremely obsolete ; carina swollen and widened in front; palpi rather robust; antennae more than half 

 the length of the body, pale flavous, the two basal joints sometimes fulvous, fourth joint longer than the 

 third; thorax about twice as broad as long, the basal sulcation distinct, and preceded at the sides by
