LAMPEIA. . 187 



Schiner is the first who correctly described the female ; that described by Macquart, 

 Dipt. Exot. Suppl. iii. p. 22, belongs to some other species. The statement of Eondani, 

 Esame &c. p. 31, that L. melanoptera, Wiedem., $ , was taken, in copula", with 

 L. clavipes, 6 , either rests on some misunderstanding, or, if true, is no more than an 

 isolated, aberrant fact. Finally, the L. clavipes, Bellardi, as I will presently show, is a 

 distinct species. Hitherto L. clavipes, Wiedem., has been found in South-America 

 only ; four specimens (3 <j , 1 $ ) from the Colombian State of Panama are, however, 

 now before me. 



2. Lampria aurifex, sp. n., <s $ . 



Lampria clavipes, Bellardi (nee Fabr., Wiedem., and Macq.), Saggio &c. ii. p. 13, t. 1. f. 15 \ 



Male. Pace clothed with golden hair ; facial protuberance with long black bristles ; underside of the head 

 with pale yellowish hair ; vertex and occiput with black bristles. Antennae black. Thoracic disc and 

 scutellum densely clothed with appressed reddish-golden hairs, the anterior and lateral margins (above 

 the dorso-pleural suture) remaining black ; pleurae black, with greyish-silvery pollen. Abdomen compa- 

 ratively narrow, slightly coarctate in the middle ; the three basal segments with appressed golden hair 

 above ; the other segments black, opaque ; the fourth segment with vestiges of golden hairs on the sides : 

 genitals black, shining, sometimes with a bluish reflection ; underside black. Legs black, bluish or 

 greenish-metallic, especially the femora ; front pair densely clothed with long, soft pale yellow hairs, the 

 two hind pairs with similar, but less dense, hairs ; hind femora with a single projecting point on the under- 

 side, near the base. Halteres pale-yellow. Wings tinged with brown ; a portion of the anal angle and the 

 alula subhyaline ; venation like that of L. clavipes, Wiedem. 



Length 15 millim. (Bellardi gives 20 millim.). 



Eab. Mexico, Orizaba (Salle *) ; Costa Rica, Cache (Rogers). 



Two male specimens in the British Museum (collected by Salle near Orizaba) agree 

 with the above description. Prof. Bellardi' s collection contains a single male, which 

 is a little larger than mine. Of the female I have three specimens, of which the 

 largest is 14, the smallest about 10, millim. long ; these have no projecting point on 

 the underside of the femora; the legs less stout and less hairy; the wings lighter 

 brown ; and the golden pubescence on the first abdominal segments less conspicuous, 

 often rubbed off. 



Prof. Bellardi was well aware of the difference between this species and L. clavipes,. 

 Macq. ; it was upon Bigot's advice, based on the comparison of typical specimens (?), 

 that he admitted the identity (see Bell. Saggio 1. c). 



L. aurifex differs from L. dives, Wiedem., in being larger, in having the apical half 

 of the abdomen black, &c. 



3. Lampria spinipes, $ . 



Dasypogon spinipes (Fabr.), Wiedem. Aussereur. zweifl. Ins. i. p. 525 \ 



Hab. Panama, Bugaba (Champion). — Brazil 1 . 



I refer to this species a single female, 12 millim. long, from the Colombian State of 

 Panama; it differs from all the South -American specimens of L. spinipes that I have 

 seen in having the black with a very slight purplish (not metallic blue or green)
