 The female sex of the present race differs from males as described for the 

 female of vl aristus on page 51 except that the tcpinina are more similar and 

 are always moderately well separated.'* Interval between the mesosternal

For convenience in comparing the measurements, we give the following for 

 the type of modestus ?nodestiis Bruner, a female from Lerdo, Durango, Mexico. 

 Length of body, 31.1; length of pronotum, 6.9; width of iironotum, 6.5; length 

 of tegmen, 4.9; width of tegmen, 3.7; width between tegnuna, 2.3; length of 

 caudal femur, 15.8; width of caudal femur, 4.8 mm. 



The extremes of caudal femoral width are; cf , 3 to 3. 8; 9 , 3. 1 to 4. 4 nun, 

 I'he variation in width of th(> interval between the tegmina is; cf, .1 to .8; 9 , 

 .8 to 1.7 mm. 



In general coloration the present race agrees closely with moiiestas aristus 

 except that the majority of specimens have the general coloration darker, 

 sayal brown, sometimes as d(;ep as suffused bister. In consequence, the 

 markings are less striking and the general appearance not as brilliant. Thi> 

 dark markings of the pronotal disk show decidedly less curvature, in Ih" 

 great majority of sj)ecimens being subjiarallel and in a few of maxinuim in- 



■* Varying in the large series at hand fr )m .8 to 1.7 mm.

 th;it this sp;ice is individu;illy decidedly variahie in the M('lano])li, and can 

 c(^rtainl\' not be used as of high geiu'i'ic or specific significance as was supposed
