carina only visible between the antenna! sockets, lower front pale 

 yellow. Antennae yellowish brown with joints five to eight a little

 sulcus, yellowish brown. Scutellum bicolored. Elytra wider towards 

 the apex, strongly costate with the intervals geminate striate punctate, 

 pale yellowish brown with a wide piceous vitta from the humerus down 

 the side not reaching the middle, a common sutural vitta of about the

Figure 73 



Between 6.5 and 7.5 mm. in length, elongate oblong oval, somewhat 

 shiny although alutaceous, the elytra strongly costate with the inter- 

 vals between geminate striate punctate, pale yellow brown with a 

 piceous head and broad piceous fascia across base of elytra and two 

 large piceous spots at apex not quite meeting at the sutm'e, other 

 specimens less hea^aly marked; antennae with the intermediate 

 joints darker. 



Head with the interocular space fully half as wide as head, frontal 

 tubercles not very well marked and a depression above; in the male 

 no sign of a carina, the area below the antennal sockets depressed; in 

 the female not quite so depressed with a fine line scarcely at all 

 elevated marking the usual carina, below the depression the lower 

 front a little bulging; occiput shiny and finely punctate, head shiny 

 piceous down to the paler mouthparts. Antennae with the basal three 

 and terminal four joints pale yellow brown, the middle joints deeper 

 brown. Prothorax considerably wider than long with nearly straight 

 sides and a transverse depression, strongly and moderately densely 

 punctate, entirely pale. Scutellimi pale. Elytra with seven or eight 

 costae on each elytron, the intervals being more or less geminate 

 striate punctate; sm"face faintly alutaceous, a broad piceous fascia in 

 basal half not reaching the middle; in one specimen with a narrow pale 

 median area near the base, and another fascia divided into two spots 

 by the sutm-e near the apex; in one specimen the basal fascia only a 

 humeral and sutural elongate spot. Body beneath pale with the 

 breast dark, legs pale, front tibiae and first tarsal joint of the male not 

 enlarged, a spine at the apex of tibiae, claws appendiculate. Length 

 6.5-7.6 mm.; width 3.3-3.9 mm.
