Madame Merian was tlie first to figure a species of this genus. 

 Her figures were named and described by Linn^us, wliose description 

 applies to the perfect female insect, his name having obviously been 

 suggested by a fanciful resemblance of the swellings on the sides of the 

 pronotum in the supposed nymph to series of scrofulous tumours 

 (strumce) . 



Fig. 5, $ . 



The accompanying outline drawing of the pronotum of a specimen 

 when superposed upon the same part of Merian's figure, accurately coin- 

 cides therewith. 



Stoll's figare 42 without doubt represents a specimen of the same 

 species.
