16 INSECUTOR INSCITI^ MENSTRUUS 



proboscis is very long and slender as in lunata and not like 

 longipalpis, pallidiventer and moralesi. It is not rapax, because 

 the abdominal colors are separated in a nearly straight line, 

 although there are some peacock scales on the scutellum visible. 

 It is not dicellaphora, because the mid lobe of the scutellum is 

 not silvery. 



Runchomyia was preoccupied by Rhynchomyia Rob. Desv. 

 and Binotia proposed as a substitute by Blanchard in 1904. 

 Goeldia Theobald (1903), however, is available. 



Goeldia fluviatilis Theobald. 



Based upon a male. Later a female was added. This is in 

 poor condition with only one mid and one hind leg. It is still 

 recognizable as a rubbed female of Prosopolepis flui Bonne- 

 Wepster and Bonne. It came from British Guiana. 



The male has disappeared. It is described, however, with 

 an incomplete white ring on the hind tibiae. There is but one 

 allied species with this character, viz., Lesticocampa moralesi 

 Dyar and Knab. There is nothing in Theobald's description, 

 which does not fit this species except the presence of scales on 

 the postnotum. Theobald did not see these scales, however, 

 and only mentions them because Lutz wrote him they were 

 present. There was probably some confusion. A few striking 

 characters of moralesi are also mentioned in Theobald's de- 

 scription of Goeldia fluviatilis, viz., the length of the female 

 palpi (one-third), the white scales of the prothoracic lobes, 

 the broader scales on the scutellum and the back part of the 

 mesonotum and the tibial ring of course. 



For all these reasons we consider Lesticocampa moralesi 

 Dyar and Knab a synonym of Goeldia fluviatilis Theobald. 

 We believe that the so-called male type of Goeldia fluviatilis 

 was placed by some error by Theobald with his specimen of 

 Hyloconops longipalpis and that the female with the ringed 

 hind tibi?e we found there, represents the missing male of 

 Goeldia.
