166 INSECUTOR INSCITI^ MENSTRUUS 



there are more blue scales and more pure white scales forming 

 lateral patches on the abdomen. We have Sabethoides nitidus 

 also from Surinam, but compared with this species it is differ- 

 ent. Sabethoides imperfectiis could with almost equal right 

 be called a Sabethinus, showing that these two ill-defined 

 genera may not be held separate in the future. 



Two females were captured while biting us in the woods.

Lemmamyia pseudomethysticus, new species. 



We found larvae of the three species of the old genus 

 Liinatus, but we bred four females from larvae in fallen palm- 

 leaves and tree-holes, which have all the characters of Limatus 

 durhamii Theob. : First abdominal segment with golden scales, 

 mid legs without white ; the colors on the abdomen, however, 

 are separated in a straight line as in methysticus Dyar and 

 Knab. The hind legs have one claw only, of course. The 

 larvae come nearer to those of methysticus than to those of 

 durhami. They have eight teeth on each side of the mental 

 plate and the mandibles have four teeth, both as in methyticus ; 

 durhami has seven and five, so has cacophrades. Limatus 

 methysticus D. & K. has been removed from the genus Limatus 

 by Dyar and made the type of a new genus, Lemmamyia on 

 genitalic characters. We take the risk, and place this new 

 species in this same genus. Only further breeding can prove 

 whether it belongs there or not.

Dendromyia roucouyana, new species. 



Female. Proboscis moderate, swollen apically. Palpi short, 

 one-fifth of the proboscis. Antennae moderate. Clypeus nude. 

 Occiput clothed with dark flat scales, a small white spot at the 

 vertex, a large white patch at the under side of the head 

 following the eye-margin for a short distance. Prothoracic 

 lobes well separated, with dark scales with brilliant violaceous 

 blue reflection. Mesonotum with broad elliptical brown scales 

 with grayish violet reflection. Scutellum trilobate, vestiture as 

 that of mesonotum. Postnotum with a group of setae. Abdo-
