ATYPOPHTHALMUS, mihi, gen. nov. 



Allied to Limnohia, Meig., from which it differs only in the 

 eyes being absolutely contiguous in both sexes from the vertex to 

 half-way to the base of the antennae ; they are also contiguous on 

 the lower side in both sexes. 



There is a distinct neck ; the proboscis is about half the 

 height of the head ; the male genitalia are large and conspicuous. 



Atypophthalmus holopticus, mihi, sp. nov^ 

 cf 9 . Calcutta. Long. 4^ — 5 mm. 



Head. — Vertex and back of head yellowish grey with long 

 stiff hairs. Eyes contiguous above in both sexes for a considerable 

 distance, below which is a very narrow, short grey frons ; they 

 are also contiguous on the under side. The surface of the 

 eyes is bent inwards.' Proboscis, palpi and antennae brownish 

 yellow or pale brown, the joints subcylindrical, a little elongated ; 

 the last joint attenuated, "' pinched " towards the tip, making it 

 appear almost like two joints. 



Thorax. — Dorsum brownish yellow. Three brownish oval 

 spots, the upper one taking the place of the usual median stripe, 

 situated just in front of the suture, but only extending half-way 

 to the anterior margin, the other two spots placed behind the 

 suture in the usual position. Scutellum of the same colour as 

 these spots. Sides of thorax and metanotum brownish yellow, 

 the centre of the latter brownish, a lateral dark brown stripe 

 across the pleurae. 



Abdomen in cf blackish, in 2 more dark brownish, shining; 

 belly in cf with the basal part of the basal segments yellowish, in 

 the 9 belly almost wholly yellowish. 



Genital organs in cf large, conspicuous and complex : — 



A large squarish brown dorsal plate, with the corners rounded 

 and the hind margin emarginate, with stiff black hairs on its 

 dorsum and long yellow hairs on the hind margin. The large 

 first joint of the claspers is irregularly shaped, longer than broad, 

 narrower apically, where from an invaginated recess issue from 

 each joint a strong black hook and a moderately long cylindrical, 

 yellowish appendage of softer texture with hairy tip. A very 

 distinct inner pair of claspers are two-jointed, the first joint 

 approximately ovate, narrower at the tip, the second joint 

 evidentl}^ hard, horny, shining brown, in the shape of a long hook. 

 There is also a peculiar, large central piece, apparently fleshy, 

 yellowish in colour, with an obtuse tip which reaches posteriori}^ 

 not beyond the first joint of the inner pair of claspers. This 

 central piece is enlarged below into a sort of cup-shaped cavity 



1 This may be accidental, or due to shrinking after death, but the specimens 

 are in perfect condition otherwise, and show no trace of damage ; moreover, the 

 feature indicated is present in both eyes of both specimens.
