Differs in the key from the Geometridae in the abdomen having the basal 

 stigmata dilated into vesicles.

Lemonia lldbii., Vcrz. p. 1S7 (1827), ty^e taraxaci. 



Differs in the key from the Brahmaeidae in having the proboscis absent. 



Family SEMATURIDAE Guen. 



DiSers in the key from the Geometridae in having the antennae more or less 

 dilated towards extremity and the eyes liauy, whilst in the Geometridae the very 

 few genera which have the antennae dilated always have the eyes naked. 



It is closely related to the Uraniadae, but has the eyes hairy and overhung 

 by long cilia and the forewing with veins 0, 7 stalked with 8 and 10, absca;, 

 instead of veins 6, 7 being remote from 8, and the eyes smooth. 



KEY TO THE GENERA. 



A. Frenulum aborted and not functional ; hmdwing with 



anal lobe produced to a long spatulate tail at veins 5, 

 4, veins 2, 3, 4 stalked ; palpi with the 3rd joint 

 long ; tibiae spined ...... Sematura 



B. Frenulum fully developed ; hindwing with vein 2 from 



near angle of cell, 3, 4 from angle or veryshortly stalked. 



a. Hindwing with anal lobe produced to a short 



spatulate tail at veins 5, 4 ; palpi with the 3rd 



joint moderate ; tibiae not spined . . Coronidia 



b. Hindwing without anal lobe, the termen jjroduced 



to a point at vein 4 ; palpi with the 3rd joint 



moderate ; tibiae spined .... Lonchoiura 



c. Hindwing with the termen evenly curved and 



without anal lobe ; palpi with the 3rd joint
