any other genus ; whether they are branches of the scales or what 

 I cannot say, but they appear to be connected with them. 

 Maxillary palpi 5-jointed ; blades of maxillae widely membranous 

 on their inner margin, especially at the apex; the thickened ex- 

 ternal rib produced at the apex in the form of a hook : base or 

 dorsal plates of the paraglossse, when these organs are closed, 

 ensheathing the base of the lingua ; the lateral portions of the 

 paraglossse extend from behind the middle of the dorsal sheath 

 in very long, slightly curved processes to beyond tlie apices of 

 the labial palpi ; their inner margins widely membranous at the base, 

 the membrane gradually narrowing towards the apex, and dis- 

 appearing at a point about a quarter of the entire length of the 

 paraglossse from the apex. Lingua very elongate ; mentum be- 

 neath elongate, parallel-sided, receiving the sclerites of the hypo- 

 pharynx near the base ; 1st and 2ud joints of labial palpi very 

 wide, their inner margins widely membranous, 1st nearly twice 

 the length of the 2nd, 3rd and 4th short, cylindrical and divergent. 

 Submentum very long ; arms of the lora very long and strongly 

 developed ; cardines wide and slightly curved ; base of the 

 maxillae clothed with very long plumose hairs.

In this genus the labrum is transverse, largely rounded in 

 front, the apex of the epipharynx shows beyond it, narrow, 

 truncate at the apex, with the corners of the truncature rounded. 

 The scales of the maxillse are oval, strongly developed, and set 

 with strong testaceous bristles along their margins. The sclerites 

 of the hypopharynx are very divergent, and extend under the 

 maxillse to beyond their palpi, whence they approach the sub- 

 mentum at right angles, just at its juncture with the mentum. 

 The maxillary palpi are 6-jointed ; the blades of the maxillae are 

 long, narrow, convex above, with a narrow parallel membranous 

 inner margin, through which, near the apex, a few hairs can be 

 seen fringing the thicker portion on its concave side. Sides of 

 the mentum produced and folded over the upper surface, their 

 edges touching each other for a short distance about the middle 

 and then diverging rapidly to the base of the labial palpi ; these 

 are attached more laterally than in any of the preceding genera, 

 and their attachment can be plainly seen from above ; the basal
