■CULEX TECTENSIS, Sp. 110V. (Text-fig. 4.) 



One specimen (a female, I. 9324) is clearly distinct by venation 

 from A. protolepis and is too small for O. protorliinus ; though 

 imperfect, it shows sufficient characters to warrant description. 



The palpi are well preserved, the second segment being about 

 1*6 times as long as the first, and slightly stouter ; there is no 

 trace of a small terminal segment. Only the base of the proboscis 

 is visible. Several antenna! segments are present, and show the 

 normal structure. The abdomen has the tip missing. Only a 

 portion of one wing is present, but this shows the most important 

 points. Sc is long, ending considerably beyond the base of -R4+5

and immediately above the base of it!,. The upper fork-cell is 

 very long, almost three times as long as its stem ; the lower fork- 

 cell is missing. The upper fork-cell shows a number of long, 

 linear scales. The length of the portion of wing preserved is 

 1*6 mm. ; the whole wing would be about 3 mm. long. 



The length of Sc and of the upper fork-cell points to the strong 

 probability that this is a species of Culex in the modern sense. In 

 living Aecles, Sc seldom extends beyond the apex of Us, and the 

 upper fork-cell is nearly always shorter. 



Tj^iorhynchus (?) cockerelli, sp. nov. (Text-fig. 4.) 



There are two blocks (I. 10106 and I. 17190) of a female of 

 another distinct species ; one block is the counterpart of the other, 

 but through unequal damage the left wing is better preserved on 

 one block and the right wing on the other. The state of pre- 

 servation is rather poor, but the following points can be made 

 out: — 



Length of body = 4*8 mm. ; length of proboscis = 22 mm. ;
