again, the hinder femora are just perceptibly lighter in tint than those of the species 

 referred to, and the dark colour at their extremities is more narrowly restricted to the 

 knee. In transmitted light the legs of H. modesta appear more translucent than those 

 of H. nervidosa. In the marginal area of the fore wing (counting along the suhcosta) 

 are 4-6 obsolescent cross veinlets before the nodus, and beyond that 3-4 obsolescent 

 followed by 11-16 well defined in the pterostigmatic region ; of these last many are 

 simple and straight or curved, but in many specimens some amount of irregularity is 

 noticeable in the veinlets of the widest part of that region, some of them forking near 

 the costa, and a few anastomosing with each other. 2 very similar, according to Dr. 

 Hagen, with brown eggs. Length of body, 6 6-7, 2 9 ; wdngs, d 8, 2 9 millim.

HaBROPHLEBIA UilBRATILIS, sp. nov. 



Subimago [dried). — Wings light blackish grey, with opaque neuration. 



Imago, 6. — Upper portion of oculi reddish during life. — (Dried.) Tlioras piceous, 

 appearing pitch-brown or pitch-black according to the direction and the amount of light 

 in which it is viewed. Abdomen above pitch-brown, with segments 2-7 to a slight 

 extent translucent towards their bases, the pleural margins sometimes remaining dark 

 throughout ; the same segments beneath are more extensively translucent, with their 

 joinings pitch-brown and their ganglionic cord subtestaceous, their general colour during 

 life being probably greyer than that of the dorsum. Setce greyish white or warm sepia- 

 grey, with their alternate joinings warm sepia-brown. Basis and proximal joints of the 

 forceps concolorous with the venter ; the remaining joints greyish white. Penis trans- 

 lucent yellowish white, with well- developed reelinate slender spurs beneath. Fore femur 

 and tibia in opaque view pitch-black, the latter darker at the tip, the tarsus testaceous ; 

 the femur reflects pitch-brown, the tibia a browner tint than the very light testaceous 

 tarsus ; in transmitted light the femur becomes warm translucent pitch-brown, the tibia 

 light brown-oclireoiis amber, with its extremity somewhat opaque, the tarsus whitish 

 yellow-amber. Hinder legs of lighter colour ; the trochanter yellowish white ; in opaque 

 view the femora appear bistre-brown or piceous-grey, more opaque towards their distal 

 extremities than elsewhere, and the remainder of the legs dull liglit brownish testaceous ; 

 the femora reflect a translucent light piceous-grey, darker distally, and the remainder of 

 the legs a uniform dull brownish white, of nearly equal depth with the colour of the 

 femora ; in transmitted light the whole of the leg is translucent whitish brown amber. 

 TTings vitreous ; in the fore wing the longitudinal neuration, the cross veinlets of the 

 pterostigmatic region of the marginal area, and the adjoining cross veinlets of the 

 adjacent area, viewed against an opaque background, appear either bistre-brown or 

 whitish, according to the direction in which the light falls upon them, the former colour 

 persisting longest (during the change of posture) in the cross veinlets specified, the 

 radius, suhcosta, and in the distal half of the costa, whilst the remaining cross veinlets 

 are transparent ; in transmitted light, a slight yellowish-amber tint is perceptihle in the 

 radius, suhcosta, and the great cross vein ; the marginal area contains about 3 almost
