Harpiphoriis maciilatus, Norton. 



I think the last word has not been said in the controversy as to the 

 identity of this form with Moiiostegia ignota. Mr. Mally apparently dis- 

 posed of the question (Insect Life, III., 9) by showing that M. ignota 

 had always four submarginal cells and came from a larva with immaculate 

 head, whereas H. maculatus may have three or four submarginal cells, 

 but comes from a larva with a black spotted head. 



Now I have to record the breeding of two specimens of H. inaculatiis 

 from larvae with black spotted head (as required), but also two speci- 

 mens of the same insect (three submarginal cells) from larvsB with 

 immaculate head, on strawberry, and another specimen from a similar 

 larva on raspberry. 



These observations are contradictory to Mr. Mally's conclusions ; but 

 agree wiih the original contention of Mr. Harrington, that the species are 

 identical. Another fact is in favour of Mr. Harrington's view. The larvae 

 of both forms are structurally and in habits those of Harpiphorus (or 

 Emphytus), not Monostegia, Eriocampa or Caliroa. The two types are 

 rather distinct. 



Egg. — I have nothing to add to Mr. Mally's account. 

 Stage I. — Head black or dark brown, with a black shade around the 

 eye j width .25 to .3 mm. Body whitish, rather opaque, but the food 

 showing by transparency ; distinctly annulate, no marks. Thorax slightly 

 enlarged. Rests with the body extended. 



Stage 2. — Head pale brown, with or without traces of a vertical and 

 lateral black patch; eye black; width .4 mm. Body all whitish, food 

 showing; annulate, as before. 



Stage J. — Head pale brown or whitish-testaceous, shining, the eye 

 black, immaculate or with the three black spots of the mature larva (black 

 spotted variety); width .6 mm. Body whitish, not shining, about 

 6-annulate, no marks. The larva rests with the body curled. 



Stage 4. — Head whitish to pale brown, as before ; width .8 mm. 

 Body whitish, like ground glass, only coloured by the food from within. 

 Feet on joints 6 to 13 ; thorax a little larger than abdomen ; head large 

 in proportion. 



Stage 5. — Head whitish or slightly brownish, immaculate, except for 

 the black eye, with a trace of black shades or a dusky black cloud on the 

 apex and a smoky darker patch behind and a little above the eye ; width 

 i.o to 1. 15 mm. Body as in the next stage, but without the small points;
