NEOBROTICA AND RELATED GENERA — BLAKE 283 



head pale or entii-ely dark. Antennae with the three or four basal 

 and three apical joints pale. Prothorax somewhat wider than long 

 with slightly curved sides and a transverse sulcus, surface shining, very 

 finely punctate, enth'ely pale. Scutellum pale. Elytra dull alutaceous 

 with distinct dense punctation, tending to be geminate striate between 

 the feeble elytral costae, pale yellow with dark metallic markings about 

 the scutellum down the suture at base, down the side from the humerus 

 and along the apical curve, and two spots, one before and the other 

 after the middle in the middle of each elytron. Body beneath pale 

 with the breast darker, legs sometimes entirely pale, sometimes with 

 a dark streak on the outside of the tibiae, front tibiae much enlarged 

 in the male, and first tarsal joint large. Length 5.2-6.8 mm.; width 

 2.5-3.2 mm. 



Type, male, MCZ; six paratypes, MCZ; 5 paratypes, BMNH; all 

 from Teapa, Tabasco, Mexico, collected in March by H. H. Smith. 



Other localities : Tepansacualco, Mexico, Salle, collector, Tapachula, 

 Mexico, Hoge, collector; San Isidro, Guatemala, Champion, collector. 



Remarks: The specimen from San Isidro, Guatemala, is a female 

 with distinct costae, very dull alutaceous surface, entirely pale legs 

 and only faintly darker intermediate joints of the antennae. The 

 distinguishing marks of this species are the blue or greenish lateral 

 vittate markings interrupted in the middle along the side of the elytra, 

 and, in the male, the swollen front tibiae.

 elytra distinctly and densely punctate, with traces of costae, pale 

 yellow, head with dark mouthparts and often dark about the eyes,

Head with the interocular space less than half the width of the 

 head, eyes very large, frontal tubercles distinct with a median depres- 

 sion above, occiput smooth, a few hairs about edge of eyes, a narrow 

 carina down front, a dark area usually about eyes and dark mouth- 

 parts. Antennae with the basal and apical joints paler than the 

 intermediate ones. Prothorax somewhat wider than long with 

 slightly curved sides and a tranverse sulcus across, alutaceous, with a
