Disonycha hogei Jacoby, Biologia Centrali-Americana, Coleoptera, vol. 6, pt. 1, 

 p. 315, 1884. 



Between 7 and 8 mm. in length, elongate oblong oval, shining; 

 pale yellow; dark antemiae, a small dark spot on occiput; median 

 elongate diamond-shaped spot on pronotum; dark scutellum; elytra 

 with faint paler lines as if marking the edge of a median vitta; body 

 beneath and legs except tarsi pale. 



Head with interocular space just half the width of head, a small 

 dark dot on occiput, smoothly rounded, a fovea near eye, tubercles 

 small, well marked, a bit swollen, carina produced, lower front moder- 

 ately long, labrum reddish brown. Antennae long, slender, black 

 except that the three basal joints are pale edged and the apical joint 

 deep reddish brown. Pronotum just about twice as wide as long, with 

 wide anterior angles, sides nearly straight, disc slightly depressed over 

 scutellum, entirely pale except the dark diamond-shaped spot in the 

 middle, impunctate, faintly alutaceous. Scutellum dark. Elytra 

 pale, with only the sutural edges darkened, two faint lines that are 

 paler on each elytron, as if outlining the edges of a median vitta, 

 surface shining, impunctate. Body beneath pale except the darkened 

 apices of the tibiae and dark tarsi. Length 7.7 mm., width 4 mm. 



Type: Not designated; cotype, female, in MCZ (Bowditch collec- 

 tion), from Cerro de Plumas, Mexico, Hoge; others probably in 

 British Museum. 



Remarks: Only one specimen has been examined. The pale 

 yellow coloring with very faint paler lines outlining an elytral vitta 

 is unusual and distinctive.

 brown edged with deeper brown, the wide sutural vitta joining the
