NEOBROTICA AND RELATED GENERA — BLAKE 321 



and near the suture, a third in Une with the second near the apex, and 

 a fourth at the apical curve on the side on each elytron. Body beneath 

 and legs entirely pale, spines on all the tibiae. Length 6-8.5 mm.; 

 width 3.1-4.2 mm. 



Type, female, MCZ 30672, from ^larcapata, Peru; one specimen 

 labelled "Peru," collected by AI. Kirsch, 1st Jacoby collection; five 

 specimens, BMNH, three labelled "Peru," collected by M. Kirsch, 

 and one without a label. 



Remarks: The specimens in the British Museum have the name 

 ^'Diabrotica 8-punctata Jacoby i.l." (in litt.) and those in the Bowditch 

 collection "Neobrotica 8-signata," also a manuscript name. This 

 species resembles one from Costa Rica but lacks the small spot below 

 the humerus found in that species and the antennae are shorter. 

 A specimen of this species was collected at Tingo Maria, Dept. 

 Huanuco, Peru, 670 m., by G. H. Dieke Aug. 16-25, 1951. 



Neobrotica grandis, new species 



Figure 66 



Approximately 8 mm. in length, elongate oblong oval, dull aluta- 

 ceous, not at all shmy, the elytra very faintly costate with dense, not 

 coarse punctation, pale yellow with darker mouthparts, the elytra 

 with a deep brown almost piceous spot on the humerus, another 

 before the middle and one after the middle and another at the apical 

 curve, a dark edging about the scutellum on each elytron. 



Head with interocular space half its width, a depression over the 

 frontal tubercles and finely punctate about this depression, the occiput 

 alutaceous, a narrow carina down the lower front with coarse punctures 

 on either side, entirely pale except the brown mouthparts. Antennae 

 pale with a fit tie deeper coloring in the mtermediate joints. Pro thorax 

 a little wider than long with slightly curved sides and a transverse 

 sulcus, surface dull, alutaceous with fine punctures. Scutellum pale. 

 Elytra faintly costate with the intervals irregularly geminate 

 punctate, the punctures shallow and dense, surface dull, alutaceous, 

 not at all shiny, pale yeUow with small deep reddish brown spots, one 

 on the humerus, one before and one after the middle, and one on the 

 side at apical curve, the scutellum edged with dark. Body beneath 

 and legs entirely pale, spines on all the tibiae. Length 8 mm.; 

 width 3.7 mm. 



Type, female, MCZ 30673, from Cauca, Colombia. 



Remarks: The dull alutaceous surface together with the position of 

 the elytral spots separate N. grandis from the other large spotted 

 species. It is larger as well as paler than N. colombiensis, the under 

 surface being entirely pale, and there are traces of costae which are
