thinks the red are always in the majority. McNeill ('99) re- 

 cords from Arkansas 39 atlanis with red tibiae and 42 with green. 

 Caudell ('03) found the tibiae of this species in Colorado to be 

 bright red, yellow, or blue. Cockerell ('89) calls the blue-legged 

 form cceruleipes. 



Scudder says the hind tibiae of minor are generally nearly 

 uniform in color, usually pale red or glaucous, sometimes plum- 

 beous or yellowish. Dodge (78) noted "a red-legged variety" 

 in Nebraska, of which he had taken many, but, as in our col- 

 lections, all were females. As in the previous comparison con- 

 cerning this species, the evidence is not full enough to be of 

 value here. 



Scudder ('97) records only six specimens of angustipennis, 

 all from Montana and Nebraska, describing the hind tibia 1 as 

 glaucous, feebly lutescent apically; but he has described .!/• 

 coccineipes, with bright red hind tibiae, from 59 specimens from 

 Utah, Colorado, Nebraska, and Kansas, which is now generally 

 regarded as merely the red-legged form of angustipennis. If 

 such it be, then the usual rule seems reversed in this case, and it 

 may possibly be that, after all, the two are not the same spe- 

 cies. Gillette ('04) records for Colorado a single male of an- 

 gustipennis and moderate numbers of coccineipes, but remarks 

 on the probable specific identity of the two. 



The only record of variation in florid us which I have seen, 

 is that of a single otherwise abnormal, doubtful example from 

 Colorado with pale red tibiae (Scudder, '97). 



Melanoplus packardii, a very variable species of wide range 

 west of the Mississippi, has the tibiae either glaucous or uniform 

 red, according to Scudder ('97). He had 176 specimens. 

 These showed that in this species red tibiae prevail, perhaps ex- 

 clusively, at the northward, occurring from British Columbia 

 to Montana, and thence to New Mexico and Kansas. Both red 

 and blue tibiae are seen in examples from Montana, Utah, Col- 

 orado, and Nebraska, and blue only in the specimens from Wy- 

 oming, Iowa, and Texas. Bruner ('85) received quite a num- 

 ber of examples of packardii from Oregon and vicinity, all of 

 which had the hind tibiae red, instead of bluish— the usual color
