INSBJCUTOR INSCITI^ MENSTRUUS 15 



The male genitalia are indistinguishable from those of rapax, 

 only the basal appendages seem more contiguous. 



Goeldia pallidiventer Theobald. 



A male and a female are present, sent by Lutz. They are 

 very similar to longipalpis. The male palpi are just as long, 

 the female has no wings, the male has the cross veins as in 

 longipalpis. The color of the venter is golden as in longipalpis. 

 The only remaining difference is the color of the abdomen, 

 which is more greenish blue in this species, violet in longipalpis 

 and the female palpi are one-sixth of the proboscis. The male 

 genitalia are like those of longipalpis but the basal appendages 

 are completely contiguous. It cannot be rapax because of the 

 proboscis and the stem of the second marginal cell is one- 

 third of its cell. 



Goeldia frontosa Theobald. 



There are two females from British Guiana, one of them 

 labeled type. The original description was based on these 

 females as Theobald states himself. Later on he added three 

 other specimens from Brazil, one of which he called a male. 

 He gave this male a second type label. This male is a female, 

 however, and all these three Brazilian females are females of 

 Goeldia lunata and have nothing to do with the females from 

 British Guiana. They have the colors of the abdomen deeply 

 incised, whereas the true frontosa has them separated in a 

 straight line. The male of frontosa remains unknown there- 

 fore. 



Runchomyia was founded by Theobald on the presence of a 

 conical prominence in front of the head between the tori above 

 the clypeus. This character is certainly present in Theobald's 

 type of frontosa, but also in many other species when looked 

 for. We saw it, e. g., even much more distinctly in a male 

 Joblotia digitatus Rondani, and a female Lesticocampa culi- 

 civora Dyar and Knab. It is not always equally distinct, and 

 is probably an artifact due to shrinking. Runchomyia is an 

 earlier name for Lesticocampa and nothing else. The post- 

 notum has no scales. Clypeus without scales or hairs. The
