PLATE LXII 



Figure 1, The distal end of the maxilla of Conorhinns rttbro- 

 fasciatiis, showing the cutting teeth. X 490. 



Figure la. The distal end of the mandible of the same. X 490. 



Figure Ib. The maxilla of Conorhinns, showing the positions of 

 the muscle attachments. 



Figure 2. The distal end of the mandible of Cimex rotnndatns. 

 Note the absence of teeth, and the flange ; on the 

 other mandible there is a corresponding excavation, 

 the two fitting together, x 450. 



Figure 4. A cross-section through the proboscis of Cirnex rotnn- 

 datus, to show the constitution of the food channel. 

 The mandibles lie internal to the maxillae, and form a 

 closed tube, the distinction between the two lateral 

 halves of which cannot be clearly defined. The 

 maxillae lie outside, fitting closely to the mandibles. 

 s., cellular spaces in the mandibles and maxillae ; 

 note how the convexity of one organ fits into the 

 concavity of the other, f.c., food channel, sl.gr,, 

 salivary groove in the mandibles. The labium is not 

 shown. Very highly magnified. 



Figure 5. A cross-section through the whole of the proboscis of 

 Conorhinns rubrofasciatns. l.g., the labial gutter 

 in which the mandibles and maxillae lie. f.c., the food 

 channel (separate parts not shown), sl.gr., salivary 

 groove, tr., trachea, hy., hypodermal cells, of conspic- 

 uously large size in this situation, mu., retractor 

 muscles, by means of which the labium is withdrawn 

 when the piercing parts enter the skin. X 500. 



Figure 6. The terminal portion of the leg of Cimex rotnndatns. 

 Note the pair of claws, and the peculiar fringe of 

 hairs at the base of the tibia. 



Figure 7. The labium of Cimex rotnndatns, seen from behind. 

 The first of the four joints is semi-membraneous, and 

 is not easily seen in cleared preparations, x 132. 



Figure 8. The wing of Conorhinns rubrofasciatns. em., em- 

 bolium. cl., clavus. c., corium. mb., membraneous 

 area. X 7. 



Figure 9. The labrum of Cimex rotnndatns, showing the two 

 joints, which are bent so as to cover the basal part 

 of the proboscis. 



Figure 10. The proventriculus and cardiac salivary glands of 

 Conorhinns ri4brofasciatns ; the villi into which the 

 wall is thrown are indicated by the dark shading, as 

 seen in a stained preparation,
