of an object, but by applying the retinal compensation and the retention 

 of images a great many otherwise incomprehensible points may become 

 reasonably clear, notwithstanding that we do not know for certain the 

 locality of the projected image as we do on the retina of the vertebrate 

 eye. We surely must be convinced by even the most superficial obser- 

 vation that insects see, and see very sharply. It may be even pardonable 

 to presume that insects are not color blind, and that not merely shades 

 direct their motions. 



Accessory assistance by touch or other senses, even mental co-opera- 

 tion ought not, in my opinion, be excluded or flatly denied. Moreover, 

 to call, as some pretentious pastors do, the non-meaning term " instinct" 

 to the assistance of science, is simply covering ignorance and indolence,

 Goethe's Faust. 



Remark. — Those who have had opportunity to observe blind cave in- 

 sects and the effect of light on them could furnish valuable suggestions 

 on that subject. 



LARVA OF ORNEODES. 



By H. G. Dyar. 



I am able to add a reference to the Orneodidae to my article in 

 the February number of the News, pages 38-40. The larvae 

 were received just too late to make the correction. 



From the larval characters, Orneodes hexadactyla belongs to 

 the most typical section of the microlepidoptera. I have received 

 also a number of larvae of Pterophoridae. Some of them possess 

 the characters of the micros, so that my super-families Micro- 

 lepidoptera and Anthrocerina are not sharply separated. This 

 indicates that the Orneodidae and Pterophoridae are not so very 

 distantly related. 



I have also before me the larva of Heterogynis paradoxa. As 

 it is an exposed feeder, it has lost the circle of hooks on the pro- 

 legs and possesses the structure of the " Macrolepidoptera." 

 Nevertheless, the larval setae show it to belong to the micros, as 

 do also the characters of venation. 



This number contains thirty-six pages.
