lit! [January 



prises the broad, but short, front, with a group of black ocelH on each side; 

 the anterior one showing the upper surface of the parts of the mouth. 



AnteMnse, inserted immediately before the ocelli, almost half so long as 

 the body, setaceous; they have two cylindrical basal joints, the second 

 longer than the first; the remainder of the antenna is very slender, grad- 

 ually attenuated towards the tip and consisting of numerous short joints, 

 of which more than 150 can be counted. 



No distinct epistoma; Jahrwm occupying only one third of the breadth 

 of the head, nearly as broad as it is long, narrowed posteriorly, rounded 

 on the sides, and with a broad excision anterioi'ly ; it bears several bristles. 



Mandibles stout at the base, attenuated towards the tip, which is point- 

 ed; arcuated on the outside and slightly excavated on the inside; their 

 direction being nearly parallel to the longitudinal axis of the body, they 

 do not cross nor touch each other; their color is pale, brown only at tip. 



MaxiJIpe. elongated, fleshy, ending in a coriaceous, yellowish-brown lobe, 

 ciliated on the margin; an oblique brown suture runs from that lobe down 

 a part of the maxilla, thus separating a narrow piece on which the palpus 

 is inserted; the latter placed on a cylindrical basal tubercle, resembling a 

 fifth joint, elongated, almost longer than the maxilla, 4-jointed; joints cy- 

 lindrical, slender; the first is the longest; the second and third of equal 

 length, shorter than the first; the fourth still shorter and more slender. 



UnderJip very large, covering a considerable portion of the underside 

 of the head. It consists firstly of a trapezoidal basal piece, immediately 

 adjoining the anterior margin of the thorax; secondly of a large, rounded, 

 cushion-like piece, on the anterior sides of which the palpi are inserted; 

 the latter are 2-jointed and uniisually distant from each other; thirdly of 

 a lingua, slightly projecting from behind the latter piece and ending in 

 three stout bristles. 



Flrat thorncic segment elliptical, convex and smooth above, twice broad- 

 er than long, its sides rounded, lined with a few bristles; its anterior an- 

 gles hardly indicated. Second and thire/ segments transverse, shorter 

 than the first, but of the same breadth; smooth above, somewhat rounded 

 and ciliated on the sides. These three dorsal segments project considera- 

 bly beyond the ventral ones. 



The firt ;irc rather long; coxfc large, placed obliquely inwards, those of 

 each pair touching each other at the tips; femora and tibi?e cylindrical, 

 clothed with sbnvt bristles; ungues slender, elongated, spinose about the 

 middle. 



Abdaniiii with eight dorsal and nine veiiti'al segments; smooth and con- 

 vex above and below; lateral edaes sharp, clothe I with soft hairs; seaments
