1G6 CATALOGUE OF DIPTERA 



Wings, as in M. rtides : head grey, with a broad black frontal 

 stripe : antennae black : thorax in front with greyish reflec- 

 tions, but not in distinct lines : abdomen brassy olive, with 

 greyish reflections in the usual place. 



Lispe litorea. 



More common on the sea-coast than L. tentaculata ; the middle 

 feet of the male are very short. 



L. adscita. Cinerea, tJiorace vittis, abdomine maculis nigri- 

 cmitibus, f route aterrimd macula acuminata Candida. 



Differs from the characters of the genus by the naked seta, and the 

 linear palpi scarcely thicker at the end : the face is most brilliant 

 silvery white : the antennae in the male as long as the face : the 

 whitish triangle of the vertex is produced to the base of the 

 antennae, and in front is silvery white : thorax blackish, with 

 very obscure cinereous lines : the sides slate colour : the abdomen 

 is flat ovate, with a blackish triangular spot on each side of the 

 second and third segments, leaving a grey line dowTi the middle : 

 the fourth segment is grey, with a blackish spot : legs black, 

 with long slender tarsi, the middle pair very long : wings 

 hyaline : the transverse nervure straight and perpendicular. 

 (Length .22; exp. .41.) 



In the female, the antennas are shorter than the face, with the third 

 joint obliquely attenuate : the triangle of the vertex is dull white, 

 not reaching to the antennae : the black front is bordered along 

 the eyes with straw colour : the thorax is cinereous, with three 

 broad and very conspicuous blackish stripes : the scutel blackish 

 at the sides : abdomen as in the male ; the last segment has only 

 a narrow black line : legs scarcely shorter than in the male. 

 (Length ,26.) 

 Though not perfectly agreeing with Lispe, this species has 



more similarity in general form and character to this than any 



other genus. The hypopygium of the male is more thickened; 



but not inflated as in Ccenosia. 



SCHOENOMYZA. 



Os mystacinum : oculi aequaliter remoti : antennae basi approxi- 

 matae, apice devaricatae, subdeflexae, articulo tertio oblongo obtuso, 

 basi seta dorsali nuda : abdomen quadriannulatum, pilosum : 

 aloe incumbentes parallelae, nervo transverso apicis nullo. 

 Tliis genus may be known from Cocnosia, which it most 



resembles, by the incumbent antennae and inflated hypopygium
