1919. Pseudodiaspis parkinsonicE (Ckll.), Ferris, Contrib. Know!. Coccida? 

 Svv. U. S., Stanford Univ. Pub!., 56; Fig. 30. 



Through the kindness of ProfeSvSor Cockerel! I have been enabled to examine 

 "type" slides of all the above species. There is not much room for question 

 that they are the same. In the specimens of yiiccce the lobes are shorter than 

 in the others, but otherwise there is no difference, and I suspect that, as not 

 inlrequently occurs, the lobes in these specimens are worn or Ijroken off. 



Lepidosaphes hawaiiensis Maskell. 



1894. Afytilaspis flava var. hanviieusis Mask., N. Z. Trans., 27: 47. 



1914. Lepidosaphes erythrincc Rutherford, Bull. Ent. Res., 5: 204. 



1910. Lepidosaphes moorsi Doane and Ferris, Bull. Ent. Res., 0: 401 ; f. 3. 



1919. Hoivardia moorsi (D. & F.), Brain, Bull. Ent. Res., 9: 220; pi. 

 13. f. 132. 



Mr. E. R. Sasscer has called my attention to the fact that L. moorsi appears 

 to be identical with Maskell's L. flava var. hawaiiensis , and after the examina- 

 tion of a photograph of the pygidium of the latter I am entirely disposed to 

 agree. I have at hand some specimens from Ceylon which agree with the 

 description of L. erythrince, and there is not much doubt that this too is the 

 same. It is evidently a widely distributed tropical and subtropical species. 



Brain has recently referred the species to Hoivardia, but it is most certainly 

 not congeneric with H. biclavis. For that matter it is hardly a Lepidosaphes 

 but it may well remain in the latter genus until revisional studies have been 

 made. There is no evidence that it has anything to do with L. flava. 



DESCRIPTIONS OF A FEW NEW DIPTERA. 



BY NATHAN BANKS. 

 Museum of Comparative Zoology, Cambridge, Mass. 



The types of the following new species are in the Museum of Compara- 

 tive Zoology. 



Euparyphus pretiosa, sp. nov. 



Differs from crotchi as follows: Legs wholly yellow, the median black stripe 

 from vertex mark to antennae does not go below antennae, the submedian pair 

 of stripes on thorax extend a little beyond the suture, are broader posteriorly 

 and slightly approximate there, the hind part of lateral stripe is longer, the 

 upper pleural stripe is longer and has a forward extension, the spots on third and 

 lourth abdominal segments are much larger and almost meet in the middle, 

 venter wholly pale (mostly dark in crotchi). The scutellum is yellow, broad, 

 and the spines are far apart as in crotchi; the discal cell is clearly outlined; eyes 

 pubescent. 



Length 7.5 mm. 



Vancouver, one female. 



E. septemmaculata Adams agrees with E. crotchi. 



Nemotelus melanderi, sp. nov. 

 Black, i)olished, without pale marks, in some a faint lateral margin to 

 thorax, the extreme tips of femora, bases of tibiae and tarsi pale; halters pale, 



ch. 1920
