gous with the galea of the locust's maxilla, rather than with 

 the lacinia, because of its two-segmented condition), extends 

 distad from the stipes as a tapering blade-shaped piece. It is 

 composed of two segments. The proximal one is small 

 and triangular, articulating by the -entire length of one of 

 its margins with the stipes. The distal segment or sclerite 

 constitutes the real blade-like portion of the maxilla, and 

 nearly equals in length the ligula and labial palpi (see be- 

 low). Its surface is unequally divided into two portions by 

 a submedian, dark-brown, longitudinal line. (This line 

 may indicate a coalescence of galea and lacinia into this one 

 blade-like compound sclerite. ) This line bears several 

 hairs, and there are scattering hairs elsewhere on the scler- 

 ite, especially towards the distal end. Near the proximal 

 end of this distal segment of the maxilla, and between the 

 longitudinal line and the outer margin, many, two-jointed 

 papillae (taste organs? ) can be seen with a high power. 



Maxillary palpi. — The maxillary palpi are minute, exar- 

 ticulate, outward-projecting pieces, arising from near the 

 outer end of the suture separating the proximal from the, 

 distal segment of the galea. 



Labium. — The parts of the labium present are the sub- 

 mentum, mentum, glossa, paraglossse, palpifer, and palpi. 



Submentum. — The submentum is a small, shield-like piece ; 

 its proximal end is connected by two chitinous bands, the 

 lora, with the cardo of each maxilla ; its distal end articulates 

 with the mentum. The submentum is rather feebly chit- 

 inized. 



Mentum. — The mentum is rather oblong in shape with 

 rounding corners and strongly chitinized. 



Glossa. — Rising from the distal end of the mentum is the 

 long glossa, which terminates in a small transparent lobe or 

 flabellum. The glossa should be carefully examined under 

 low and high magnification. Note the reticulated and hairy
