abdomen terminates in a hook, curved downwards ; the colour is a 

 deep bright yellow, a little inclining to orange-yellow ; a narrow bro^Ti 

 streak obliquely crosses each eye-piece ; three, spiracles on either side 

 are conspicuously prominent on circular swellings, paler than other 

 parts, and are like nipples of brownish-red with rather darker orifices ; 

 the other spiracles behind these are very small, flat, and brown, yet 

 can just be detected with a lens. 



I have now only Acentropus left of the known British species of 

 Hydrocampidcs to be figured, and shall be extremely obliged to any 

 entomologist who can obtain eggs or take the larva, if he will bear my 

 want in mind at the proper season.
