HEMIPTERA COLLECTED IN PERTH DISTRICT IN 1893 99 



Fig. 2. Another head ; the two inner cirri of the ventral part of the ring lost ; 

 the rest of the cranium eroded. Magnified six diameters. The entire specimen 

 represented of the natural size in Fig. 7. 



Fig. 3. Another head still more eroded, but the position of the nasal opening 

 indicated by the remains of the cirri around it. Magnified six diameters. 



Fig. 4. Anterior part of another head, magnified six diameters. The dorsal 

 margin of the nasal ring with stumps of cirri is seen, but the ventral margin is 

 broken through in the middle. 



Fig. 5. A head figured in my former paper (5, ; Plate I. Fig. 2), but here mag- 

 nified up to seven diameters. Only the ventral margin of the nasal ring is seen, 

 with obscure traces of cirri externally on each side. In this specimen the surface 

 of the skull is wonderfully entire and uneroded, but it seems just a little frayed 

 along the margins. 



Fig. 6. Part of the tail of the specimen the anterior part of whose head is 

 represented in Fig. 4, to show the dichotomisation of the neural spinous processes. 

 Magnified thirteen diameters. 



Fig. 7. The specimen, natural size, whose head is represented in Fig. 2. 



Fig. 8. Restored outline of Pahcospondylus Gnnin', altered from the figure 

 previously given (5, p. 90) in accordance with the present state of knowledge.
