No. 5,] Notes on a New Psyllid. T9 



General colour pale oehreous. Abdomen and legs piceous brown. 

 Vertex much narrower than the pionotum. Eyes moderately large. An- 

 tenna about equal in length to the head and pronotum together. Arti- 

 culations nine (?), the two basal joints globose, the third the longest of 

 all, the terminal joint nodular. 



Notum and pronotum separated by a suture, tumose, and much 

 overhanging the abdomen. This last organ is fusiform, pointed, ter- 

 minated in the male by a rounded pygofer without upright append- 

 ages, and in the female by a linear ovipositor, 



Hemelytron with a nearly straight basal cubitus, which ends in a 

 rounded sligma on the eosta, the cubitus then passes by nearly a right 

 angle towards the margin, but unlike Psylla proper, it furcates before 

 it reaches the same. The sub-cubitus starts direct from the basal 

 cubital vein and not from the marginal. It furcates and forms the 

 sub-cubital cell. 



The sub-marginal vein and its cell is absent. The wings (lower) 

 are very delicate and have three simple veins. 



The membranes of the elytra are pearly-white, ornamented with three 

 larger and several smaller brown patches, through which the nervures 

 (which are raised and marked with dark spots as we see in the cixiilse 

 Tettigidse) pass. Legs are hirsute stout, and furnished with two tarsal 

 joints and two claws. Rostrum very short, pointed, and it appears to 

 rise from between the second coxae. 



It will be seen that the above diagnosis does not well accord with 

 any genus given by Dr. F. Low either in Beetrage Zur Kenntuiss der 

 Psylloden or in his Katalog, but future observation may make the 

 above observations raoi'e complete, through a study of the immature 

 larval forms. 



Expanse of wings 0'40 of inch. 

 Length of body 0*16 „ „ 



The specimens at my disposal were mildewed from damp, but it 

 is possible that when alive the insect may have shown a slight 

 cotton-like investment.
