NOTES ON THE TYPES AND CO-TYPES OF LUCILIA SPECIES IN THE 



. U. S. NATIONAL MUSEUM. 



The following notes were made in 1911, through the courtesy of the U. S. N. 

 Museum authorities, on the types and cotypes of Mr. Townsend's supposedly new 

 species of Lucilia. In some cases the Taxonomy of Muscoidean Flies, Smithsonian 

 Misc. Col., Vol. 41, No. 1803, notes refer l^o the original descriptions. The value 

 of certain characters employed in these descriptions is discussed in the preceding 

 portion of this paper. 



Lucilia morilli. Town. 

 The type specimen together with all the co-types are Pseu- 

 dopyrellia cornicina Fab. There are no hypopleural bristles 

 and the fourth vein is curved and not angular. 



Lucilia nigripalpis. Town. 



The type specimen must be referred to L. sylvarum Meig. 

 The width of front is slightly less than one-third head width; 

 the palpi are blackish ; the first segment of the abdomen is 

 blackish; on the second segment of the abdomen there is a 

 well marked pair of median marginal macrochaetae quite as 

 strong as are found in most specimens of L. sylvarum. The 

 abdomen is however ' dented ' in consequence of which the 

 macrochaetae are appressed against it and this is presumably 

 the reason that they were overlooked by the author of the 

 species; there is a weak pair of extra ocellar bristles just posterior 

 to the ocellar triangle and quite typical of sylvarum; in the 

 comparative lengths of the apex of the first posterior cell and 

 the anterior cross vein the fly is typically sylvarum. 



The co-type is an undeveloped specimen of L. sylvarum 

 Meig; the head characters are all typical except in the color 

 of the palpi which are distinctly brownish, especially toward 

 the base; the lower side however of the abdomen and also the 

 legs both show this light color which means that the fly was 

 captured soon after issuing; toward the tip the palpi become 

 blackish and this is carried down one fourth distance to base; 

 as to marginal macrochaetae on the abdomen there is a weak 

 pair on the second segment which show up better when the 

 fly is examined from the dorsal side; when the specimen is 

 viewed laterally there is seen to be one other bristle near the 

 center of the same segment; it is about as long as the shorter 

 of the central pair but the base is weaker.
