concealed and certain transverse impressions may belong to 

 the tips of the joints themselves or to impressions across their 

 middle. The body is winged. 



EUTERMICOLA SCULPTICOLLIS, 11. Sp. 

 PI. xxxii., fig. 1. 

 Castaiieous, elevated parts of upper-surface, antennae- 

 (tip excepted), and knees darker. 



Head densely longitudinally and obliquely strigose on 

 basal half, front half highly polished and impunctate or 

 almost so. Antennae about as long as the front of the 

 prothorax is wide, all the joints, except the apical one, trans- 

 verse, apical joint flavous, about as long as wide and distinctly 

 narrower than the preceding one. Prothorax longer than 

 the apex is wide, apex finely margined, witli four longitudinal" 

 elevations commencing near the apex, parallel with each other 

 for some distance but not to base ; with a wide and deep 

 excavation on each side of basal half ; basal two-thirds 

 longitudinally strigose and somewhat asperate. Elytra the 

 width of base of prothorax, parallel-sided to near apex, 

 which is widely rounded; each with a conspicuous ridge 

 commencing at baise just outside of the scutellum, and 

 continued almost to apex, the space between it and suture 

 strongly sloping downwards on basal half, but almost flat 

 posteriorly; an acute carina commencing on each shoulder 

 and deflected downwards towards apex, between the two 

 acute carinae two others, almost as distinct beyond the 

 middle, but becoming very feeble and within a depression 

 towards base, where also there is another one which vanishes 

 before the middle ; surface in places finely rugose and without 

 distinct punctures. Prosternvm with numerous transverse 

 corrugations. Abdomen minutely punctate in middle, more 

 noticeably at sides. Length, 3-3^ mm.

The two median elevations of the pronotum are in the 

 form of narrow parallel costae on their apical half, but 

 towards the base they angularly diverge from each other 

 and then converge till they almost meet at the base, the 

 outer elevation on each side is similar to the inner ones for 

 some distance, but is then thickened and strongly curved, 

 the curved portion causing a bulging appearance near the 

 base and marking the outside of a large excavation traceable 

 almost to the middle of the base ; the junction of the pro- 

 notum and prosternum is marked on each side by a narrow 

 carina that terminates in a foveate depression below the
