Basyvalgtis pijrropygvs, Kraatz, a Malayan species, has been 

 recoi'ded by Dr. Kolbe from Burma, but as the characters he has 

 assigned do not agree well with those of the type, which I have 

 examined, J. have not included it here. 



215. Dasyvalgus dohrni. (Plate II, figs. 6 & 7.) 



Dasyvalgus dohrni, Kolbe, Stettin. Ent. Zeit. Ixv, 1904, p. 41. 



Black or very deep chocolate-colour, clothed with fine setae and 

 decorated with orange or yellow scales, which are numerous and 

 closely packed in the male, forming a very conspicuous pattern, 

 and in the female fewer, less close and inconspicuous. 



The chjpeus is long, distinctly bilobed and not closely punctured. 

 The pronotum is moderately long, bell-shaped, ^^"ith the sides and 

 base regularly and gently curved. The dorsal carinse are nearly 

 parallel and tufted near the middle and at the hinder extremities. 

 The scutellum is moderately long and blunt. The eJytj^a are deeply 

 striated and separately rounded at the end. The iiropygidium is 

 tufted on each side of the middle and the terminal spiracles are 

 moderately prominent. The front tibia is broad and armed with 

 five strong teeth and the basal joint of the hi^id tarsus is twice as 

 long as the second joint. The upper side of the hind femur is 

 clothed with grey scales. 



c? . The pronotum is covered with yellow scales, except at the 

 hinder median part, and the elytra have each a large median yellow 

 patch and usually a smaller and paler one external to it, a patch 

 adjoining the scutellum, another in the sutural angle and several 

 inconspicuous longitudinal lines of scales following the intervals 

 between the striae. The greater part of the lower surface of the 

 body is clothed with pale yellow scales. The three distal teeth of 

 the front tibia are long and acute and the hind tarsus is about 

 half as long again as the tibia. 



$ . The yellow markings of the male are only vaguely repre- 

 sented by a few greyish yellow scales. The body is more elongate, 

 the propygidium more extended, and the pygidium has a smooth 

 flattened ventral plate. The front tibia is broader than that of 

 the male and all its teeth very blunt. The hind tarsus is stout 

 and only a little longer than the tibia.
