NEOBROTICA AND RELATED GENERA — BLAKE 309 



which Dr. Selman has compared with nigroguttata and concluded they 

 are synonymous. There is one labelled ''Diabrotica oblongoguUata 

 Chev." in the same series with the same sort of green label. In 

 addition to these confusing old names, the species has been confused 

 with Neobrotica ebraea (Fabricius) which it strongly resembles in 

 its markings. It is, however, a little larger, the eyes are not so closely 

 placed, the elytral punctation is more distinct, and there are traces 

 of costae and the aedeagus is different, too. On the occiput the spot 

 is smaller in A^. oblongopunctata and there are two smaller spots 

 visible when the head is protruded. On the elytra the humeral spot 

 does not coalesce with the lateral spot below it. It is also similar 

 in elytral markings to Diabivtica significata Gahan but lacks the 

 two vittate marks on the prothorax.

Between 5 and 6 mm. in length, elongate oblong oval, shiny, 

 faintly alutaceous, the elytra very finely punctate; head pale with a 

 triangular dark spot in the middle of the occiput, dark mouthparts; 

 the thorax, legs and undersurface pale; elytra with an elongate piceous 

 marking extending from the humerus to below the middle, an elongate 

 spot near the middle of base of elytron and one before and one after 

 the middle and one laterally near the apical curve. 



Head with the interocular space less than half width of head, frontal 

 tubercles swollen, a median depression above and a narrow carina 

 down the lower front, occiput smooth and shining, head pale except 

 for a triangular piceous spot in middle of base of occiput, and dark 

 mouthparts. Antennae entirely pale except tip. Prothorax wider 

 than long with nearly straight sides, a shallow transverse depression, 

 pale, shiny, nearly impunctate. Scutellum dark. Elytra shiny, faint- 

 ly alutaceous, very finely punctate, pale with markings as described 

 above. Body beneath and legs usually entirely pale, anterior coxal 

 cavities open, a spine on the middle and hind tibiae, the first tarsal 

 joint and anterior tibiae of the male swollen. Length 5-5.9 mm.;
