SABETHOIDES NITIDUS 37 



Known to us only from the Canal Zone, Panama, but probably extends farther 

 southward. 



Tabernilla, larvge in bamboo. May 9, IG, 22 (A. Busck) ; Tabernilla (A. H. 

 Jennings). 



The species identicus is closely allied to Sahethinus undosus. The thoracic 

 ornamentation varies from metallic blue through golden-green to purple; the 

 abdomen is metallic blue, without any green tint such as occurs in undosus.

The type species are : of Sabethoides Theobald, Sabethoides confusus Theo- 

 bald; of Sabettoides Blanchard, Sabethoides confus'iis Theobald. 

 Generic Diagnosis of Adxjlt Female (Male Unknown) : 



Head moderate, the eyes large, contiguous at vertex. Proboscis long and slender. 

 Antennae with the joints subequal, the hairs of the whorls long and rather abundant. 

 Palpi very short, slender. Vestiture of broad appressed scales, the occiput without 

 erect forked scales, the mesonotum without setae on the disk. Prothoracic lobes 

 large, approximate dorsally. Abdomen subcylindrical, blunt at the tip. Legs long 

 and slender. Claws small, equal and simple. 



The genus is confined to the tropical portions of the American continent. 



The genus Sabethoides is closely allied to Sabethes. We separate it on the 

 character of the proboscis, which is not a strong one. It is not improbable that 

 if a considerable number of species should be discovered, intergrades would ap- 

 pear compelling the union of the genera. 



The larva is unknown. The adult is day-flying, blood-sucking, and forest- 

 inhabiting ; it is rare wherever found ; in the early stages it is not improbably 

 predaceous upon the larvae of other sabethines inhabiting bromeliads.
