142 INSECUTOR INSCITI.T- MENSTRUUS 



This genus may fall with the Joblotia group, as placed in the 

 monograph, but I think more probably it belongs here in the 

 Sabethes group, as placed by Lutz and Peryassu. No males 

 are known in the genus. 



TABLE OF SPECIES 



(Coloration) 



1. Scales on clypeus white confusus Lutz 



Scales on clyppus dark brown 2 



2. Larger species, legs extended 11.5 mm jocosa Dyar & Knab 



Smaller species, legs extended 8.5 mm prolepidis Dyar & Knab 



In the tables of species I have let all those of which I do 

 not know the males stay where they were. This has thrown 

 all but two of the species with violet lobes into Dendromyia and 

 all those with dark prothoracic lobes into Wyeomyia. This 

 gives twenty species of Dendromyia with only five known in 

 the male, and twenty-eight species of Wyeomyia with twelve 

 known in the male. I cannot do anything else with them until 

 the males are known. I fancy that a certain proportion will 

 prove to be synonyms. The colorational characters as used are 

 really perfectly good ; but they are so hard to see and a small 

 range of variation alters them so considerably, that mistakes 

 are more than easy to make. That there are many still undis- 

 covered mistakes in the tables, I make no doubt. 



The following species I have not been able to place, even 

 approximately. 



Phonioniyia pallidov enter Theobald, Mon. Culic, iv, 598, 1907. Brazil. 

 Phoniomyia quasilongirostris Theobald, Mon. Culic, iv, 598, 1907. 



Brazil. 

 Dendromyia mcdioalbipes Peryassu, Os Cul. do Brazil, 303, 1908. Brazil. 

 Dendromyia arthrostigma Peryassu, Os Cul. do Brazil, 306, 1908. Brazil. 

 Dendromyia bourrouli Peryassu, Os Cul. do Brazil, 307, 1908. Brazil.
