yellow. This species may be immediately distinguished from A. bellardii, Giglio-Tos, 

 which seems to be its nearest ally, by the black scutellum. 



LOPHOTELES. 



Lophoteles, Loew, Berl. ent. Zeitschr. 1858, p.TlO. 



l. Lophoteles pallidipennis, sp. n. (Tab. IV. fig. 16, $ .) 



2 . Head black, covered with whitish dust, with the exception of a slender median line and the lowermost 

 portion, which are shining. At the vertex the eyes are separated by the ocelli, the front gradually 

 widening anteriorly. Antennae black, the first two joints yellow ; arista densely pubescent, appearing 

 almost like a solid mass, in length equal to about twice that of the first three joints together. Thorax 

 deep black, moderately shining, the colour mostly concealed beneath silvery tomentum, which is arranged 

 in slender stripes, leaving the black colour apparent between them. Scutellum subtriangular, the middle 

 portion of the margin produced into a tbin edge, upon which a number of minute points are visible ; the 

 basal part uniformly and thickly silvery-tomentose, the apical portion opaque black. Abdomen black, for 

 the most part concealed beneath a dense silvery tomentum. Legs light yellow ; all the femora, except 

 their tip, black. Wings hyaline, the veins yellow and not at all stout. Length 3| millim. 



Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith). 



One specimen, which I take to be a female. The only known species other than 

 this, belonging to the genus, is L. plumata, Loew, from the Polynesian island of Radak. 

 The generic description and figures given by Loew apply very well to the present 

 insect, L. pallidipennis being easily distinguishable by the silvery tomentum. 



EURYNEURA. 



Euryneura, Schiner, Verh. zool.-bot. Ges. Wien, 1867, p. 308. 



Euryneura ? 



Hab. Mexico, Chilpancingo and Tierra Colorada in Guerrero (H. H. Smith). 



In his generic description of Euryneura (Reise der Novara, Dipt. p. 57), Schiner 

 describes the scutellum as having two long spines, a character also ascribed to the 

 type-species, E. fascipennis, by Wiedemann. In his comparative description of 

 E. propinqua, Schiner does not refer to the scutellar spines, and the assumption is that 

 they are long, whereas in E. elegans, Willist. (Trans. Am. Ent. Soc. xv. p. 252), from 

 Brazil, they are very small. Giglio-Tos [Mem. della Reale Accad. delle Sci. di Torino, 

 (2)xliii. p. Ill] identifies E.propinqua from Orizaba, Mexico, but mentions the fact that 

 the spines are small. Two specimens, male and female, from Guerrero, now before me, 

 agree almost entirely with the type of E. elegans, except in the colour of the legs and 

 antennae and in having a little broader front. In both these species the hyaline band 

 of the wing reaches the posterior margin beyond the fifth posterior cell, in which there 

 is a rounded clear spot, a character not mentioned by Schiner. Whether one or the 

 other of these insects is really referable to E. propinqua I cannot now say.
