In Chile at Valparaiso and Yaldivia. Blanchard said, Esta 

 especie parece vara en Chile. 



I have seen no specimens of this 'Species, and therefore I quote

NEUROMUS Kambur 



Adult. Color from nearly black to light yellow; usually some-

 elongated nor annular as in Corydalis. Cheek once or twice 

 toothed or with a sharp angle. Prothorax quadrangular to 

 cylindric, narrower than the head, longer than broad and shorter 

 than the mesothorax and the metathorax combined. Three 

 large approximate ocelli facing outward. Antennae always fili-

 thorax combined. INIcnlius with more than two branches 

 [fig.25] ; cross veins between branches of radius, from 10 to

 one or two accessories in some species, to four or five in others.
