that Brunner erred in uniting them. That this was done is, 
however, not at all strange, Brunner’s measurements showing 
that he had but the present species before him, although he 
should have given more attention to the features given by Bur- 
meister in the key section of the page on which both forms 
were described. Burmeister says of laevigata, '' Fltigeldecken 
reichen bis fast ans Ende des Hinterleibes und griefen liber 
einander”; while of scrobiculata he writes, ‘'Fliigeldecken merklich 
ktirzer als der Hinterleib.” The present species has, in both 
sexes, the tegmina longer than in any other form of the genus 
known to us. Serville’s name rohusta and laevicoUis are clearly 
based on the sexes of the same species which Burmeister called 
scrobiculata. 
The three closely allied species of this section of the genus, 
specimens of each of which are now before us, may be recognized 
by the following key. 
A. Tegmina not as long as or but slightly longer than the greatest width of 
pronotiim, exposing four to five abdominal segments; apex relatively broad. 
Wings shorter than tegmina. Lateral margins of pronotum of male but 
moderately arcuate. 
B. Tegmina with length little greater than their individual width; distal 
extremity subtruncate; distal portion of costal margin strongly arcuate. 
scrobiculata Burmeister 
BB. Tegmina with length appreciably greater than their individual wddth; 
distal extremity well rounded; distal portion of costal margin obliquely 
subarcuate. atlas Rehn 
AA. Tegmina about a third longer than the greatest width of the pronotum, 
exposing about three abdominal segments; apex relatively narrow, rounded. 
Wings as long as tegmina. Lateral margin of pronotum of males considerably 
arcuate. laevigata Burmeister
