DISCOVERY REPORTS 



Female (Fig. 4). Capitulum covered by a thin cuticle. Valves fourteen in number, 

 separated by distinct chitinous interspaces. The grov^^th lines in this species weakly 

 marked. 



Scutum quadrangular with somewhat 

 convex occludent margin. 



Tergum triangular with convex oc- 

 cludent margin and recurved apex. 



Carina regularly bent with the umbo at 

 the apex. Dorsal roof convex. Sides well 

 developed with wide areas in the upper 

 part. 



Upper latus pentagonal with the 

 scutal margin concave and the tergal 

 margin convex. The carinal margin and 

 the margin against the inframedian latus 

 short. The umbo is apical. 



Rostrum triangular, elongated with 

 the umbo at the apex. 



Rostral latus quadrangular with short 

 basal margin. Width of plate exceeds 

 height.

margins of the same length. The umbo pig. 4. Scalpellum bouveti n.sp. (St. 456). a. Palpus.

umbo at the middle or the carmal margm. 



Lateral, upper and basal margins nearly of the same length. 



Peduncle of the same length as the capitulum, with transversely elongated scales

Holotype 



Mouth parts: palpus conical with bristles at the point. Mandible with three teeth 

 and a pectinated inner angle. Maxilla I could not be studied in the holotype. Maxilla II 

 with bristles along the whole concave front edge. A posterior lobe with bristles is dif- 

 ferentiated like a maxillary lobe.
