shallow transverse sulcus not at all conspicuous, the elj^tra finely 

 punctate, a little wrinkled and with faint costae; piceous, the prothorax 

 pale, the body beneath except the breast pale, femora pale at base, a 

 narrow pale fascia below the middle of elytra, not joined at suture, 

 and a pale apical spot on each elytron. 



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

 polished and finely punctate, faint traces of frontal tubercles but flat, 

 and a flat interantennal area without a carina swelling out below and 

 widening; entirely dark. Antennae (in female) with the third joint a 

 little longer than second, fourth joint considerably longer than second 

 and third together and longer than the succeeding joints which are 

 subequal, piceous with the three terminal joints pale yellow. Pro-

 a very shallow transverse sulcus, scarcely visible; pale yellow, polished, 

 nearly impunctate. Scutellum dark. Elytra obsoletely and rather 

 rugosely punctate, and with traces of costae, shining piceous with a 

 pale yellow fascia below the middle interrupted at the suture and 

 somewhat depressed, a round pale spot also near the apex. Epipleura 

 vanishing at apical curve. Body beneath pale except the dark breast,

About 8 mm. in length, elongate oblong oval, the elytra finely 

 punctate, the punctures in the pale band coarser and more distinct, 

 and with a suggestion of being geminate striate between feeble traces 

 of costae, the transverse sulcus on the prothorax not marked; pale 

 yellow brown, the head, antennae and legs piceous, elytra piceous 

 with a broad pale band across the middle but interrupted at the 

 suture, apex narrowly pale. 



Head with the interocular space approximately half width of 

 head, occiput polished, impunctate, frontal tubercles distinctly 

 marked but not swollen, a median depression above them, a narrow, 

 distinct carina down the lower front, entirely dark shiny piceous. 

 Antennae with the third joint a little longer than the second, both 

 together not so long as the fourth, rest a little shorter, long and slender, 

 dark brown with the three terminal joints pale. Prothorax rectangu- 

 lar, almost twice as broad as long with slightly curved sides and
