TV. and V. very near together below the same, and VI. with two 

 hairs directly under these. On the base of the prolegs stand also 

 two warts, one exterior (VII.) and one interior (VIII.). 



" On the ninth abdominal segment I could only make out four 

 warts on each side : two dorsal ones one behind the other, and two 

 lateral ones one above the other. On the second and third thoracic 

 segments warts I. and II. stand one above the other, each composed 

 of two small single-haired tubercles on a single somewhat large flat 

 chitinous shield (I. a and 1.6, Il.a and II.6, according to Dyar) ; then 

 follow more distantly below and anteriorly (in the case of grammo- 

 dactyla), 111. and IV. likewise one above the other, and still further 



down comes VI. Wart V. seems to be absent In Orn. 



kexadactyla III. and TV. stand horizontally near one another, V. is 

 wanting or is extremely rudimentary. 



" The first thoracic and the tenth abdominal segments are pro- 

 vided with weak circular chitinous plates (thoracic shield and anal 

 shield), and are furnished with numerous small-haired warts.

OineocLi Larva. 



"The thoracic legs are of the usual pattern, generally weakly 

 chitinized. The prolegs are completely developed circle-feet ; on 

 the anal claspers the hooks form a semicircle open posteriorly. It 

 is very noteworthy that in very young larvae the prolegs and anal 

 legs are wholly without hooks. 



" The larvae are unicolorous, yellowish or reddish-white, without 

 markings ; before pupation they often assume a reddish colora- 

 tion." 



The accompanying sketch (Fig. 2). which must be taken to give a 

 general idea of an Orneodid larva rather than that of any particular 

 species, has been drawn partly from descriptions, partly from pre- 

 served larvae received from Herr A. Bang-Haas, and partly from 

 microscopic preparations of larvae of 0. kexadactyla kindly lent by 

 Dr. T. A. Chapman. 



Pupa. 



In their pupal state especially the Orneodidae are seen to be 

 strikingly distinct from the Pterophoridae, with which group, as
