GALERUCESTE BEETLES — BLAKE 241 



punctate, yellow brown with dark antennae, a piceous occiput on the 

 head and a darkening over the anterior half of the pronotum, a wide 

 dark area extending from the base of elytra over the humerus and 

 down the side, widening to cover lateral half below the middle, margin 

 and interior pale, body beneath pale with the breast brown, the tibiae 

 and tarsi and apical half of femora piceous. 



Head with the interocular space about half width of head, occiput 

 smoothly rounded, frontal tubercles distinct, a well-defined carina 

 down lower front, the occiput and around eyes piceous, front pale, 

 mouthparts brownish. Antennae piceous (last two joints missing), 

 third joint a little longer than second, remainder much longer. Pro- 

 thorax with nearly straight sides, about a third wider than long, 

 a scooped-out area in the basal half; shiny, yellow brown with the 

 anterior half darkened. Scutellum pale. Elytra shiny although 

 finely alutaceous, very finely punctate, somewhat flattish with small 

 humeral prominences and short intrahumeral sulcus, yellow brown 

 with a piceous band across base extending down over the humeri and 

 along the side and widening in apical half to cover half the elytra, the 

 explanate margin wide and pale, interior pale; body beneath pale with 

 the breast brownish, basal part of femora pale, apical half, tibiae, and 

 tarsi dark. Length 4 mm.; width 1.7 mm. 



Type, female, CAS, from Cordoba, Mexico, A. Fenyes collector. 



Remarks: Only a female of this species has been examined and 

 without the male it is impossible to be certain into which genus it 

 falls, but the front of the head resembles more the species of 

 Trichobrotica. 



Neotrichota, new genus 



Type species: Neotrichota fiavipennis, new species. 



Elongate oblong oval, head with weU-marked frontal tubercles and 

 a short carina down the lower front; antennae long and filiform, the 

 third joint longer than the second. Prothorax nearly rectangular 

 with shghtly curved sides and explanate margin, a shallow scooped-out 

 area in lower half. Elytra with small humeral prominences, sHghtly 

 wider towards the apex. Anterior coxal cavities open, middle tibiae 

 of the male notched near apex, the first tarsal joint of the hindlegs 

 scarcely as long as the rest of the joints together, claws bifid. 



This genus resembles species of Trichobrotica except that the claws 

 are not appendiculate but bifid. In this respect the genus is like 

 Deinocladus, and these two genera alone stand out as having bifid 

 claws in a group in which the claws are appendiculate. 



The name Neotrichota is derived from the Latin "neo," meaning new, 

 and "trichota," an abbreviation of Trichobrotica.
