PARAOOROTOCA AKERiMAXI (wARHEN). 361 



Fig. 27. — x 45. Side view of me.sothoracie leg, showing articukition 

 and surrounding sclerites. 



Fig. 28. — X 45. Ventral view of metatlioracic leg, showing articula- 

 tion and sclerites. 



Fig. 29. — x 60. Ventral view of left elj^tron. 



Fig. 30. — x 250. Vertical longitudinal section of prothoracic exuda- 

 tory organ, showing thick, soft, permeable cuticle. 



Fig. 31. — X 120. Vertical transverse section of prothoracic exudatory 

 organ resting on occipital region of head. 



Fig. 32. — x 180. Vertical longitudinal section of metatlioracic 

 exudatory organ, showing on one side much coagulated matter (cg.w.) 

 between the cuticle and the epidermis. 



Fig. 33. — x 180. Vertical longitudinal section through the median 

 abdominal exudatory organ. 



Fig. 34. — x 250. Vertical longitudinal section through the ventral 

 body-wall of the prothorax, showing the curious crumpling. 



Fig. 35. — X 500. Vertical section through the lateral body-wall of 

 metatlioracic region, showing the peculiarly porous nature of the 

 endostracum. and a considerable amount of coagulated matter between 

 cuticle and hypodermis. 



Fig. 36. — X 400. Transverse section through cephalic glandular 

 epithelium {(jl. ep.), showing a bilol:)ed condition. 



Fig. 37. — X 500. Vertical longitudinal section through lateral tergal 

 gland, showing mass of secretion (^e.) in the receptacle (B.). 



Fig. 38. — X 500. Vertical longitudinal section through trichome 

 and body-wall, showing trichogenic cell (tri. e.) and the communication 

 with the exterior, around the liase of bristle, of the space between the 

 cuticle and the epidermis. 



Fig. 38 a. — X 250. Spiracle opening on tergum IX, seen from the 

 outside. 



Fig. 39. — X 325. Vertical cross-section of head, showing the dis- 

 connection of the optic {op. g.) ganglion of the brain and the optic plate 

 {op. p.) of the compound eye. Note {he degenerate character of the 

 ommatidia and the ingrowing cuticle {i. c.) tending to cut off the eye 

 from the inside of the head. 



Fig. 40. — x 325. Section through the eye, less central than that of 

 fig. 39; here the ingrowing cuticle {i.cu.) forms a continuous i^artition. 



Fig. 41. — X 80(). Vertical section of portion of degenerate compound 

 eye showing abundance of pigment, but cone-cells, and especially the 

 rhabdome cells, are very degenerate.
