The evidence cited above is certainly sufficient to synony- 

 mize nc.va with fansfinitla ; the var. fnsca of Stretch is nothing 

 but a dark example and has no right to be called a variety. 

 The synonymy therefore should stand thus : 



Illicc faiistinnla Boisduval. 



Syn. uc.va Boisduval, fusca Stretch, ^r/sca Packard, 

 dcserta Felder. 



A few eggs were obtained from a fertile fausjinulii ,- they 

 are silvery white, reticulated and somewhat flattened at the 

 base. A small number of larvae in the first stage were secured 

 from these eggs by Mr. Grinnell, who gives the following 

 description of them. 



Illicc faustinula Bel. First stage : Width of head 20 microns, 

 of eleventh segment 19 microns, of sixth segment 16 microns. 

 Body whitish, transparent ; a little light brown pigment to- 

 wards the cephalic and caudal extremities. Head, shining 

 brown with a few short hairs. Body covered with long black-

 drical, but somew r hat flattened dorsally. Legs same color as 

 adjacent parts of body. Head strongly bilobed. 



Concerning the Locust Genus Mestobregma, Scudder 



BY LAWRENCE BRUNER, University of Nebraska. 

 The generic name Mestobregma ("Bull. U. S. Geol. Surv. 

 Terr., II, p. 264, June 6, 1876) was erected by Samuel H. 

 Scudder for the reception of an insect which he erroneously 

 took to be Ocdipoda pliittci of Thomas (Scudder in litt. to 

 Bruner), but which in reality was the one described later by 

 Henri de Saussure as Psinidia ( Trachyrhachis) pardalina 

 (Prodr. Oedip. p. 162, 1884). Since the species chosen by 

 Scudder for the type of his new genus Mcsfo/u-f^nnt was un- 

 described at the time, and wrongfully supposed to be another 

 and very distinct insect, the name will have to be replaced by 

 another. During the same year Scudder suggested the name 

 TriicJiyrhacIn's (since corrected to 'rntcliyrlnichh} for the recep- 

 tion of two new species of locusts which he deM-i iUd from the
