OF WASHINGTON. 45 



uncus, which is bent inwardly and acute at tip,* middle and hind tibiae 

 distinctly widening from base to apex, hind tibia; slightly narrower than 

 the middle tibiae; tarsi slender, as long as the tibiae, third joint very little 

 wider than the second joint and hardly bilobed, fourth joint very small, 

 claw joint as long as the rest of the tarsus. Length, 2.1-2.3 mm - 

 Locality : Key West, Fla. 



Described from many specimens which I found, in April, 1887, 

 under the bark of Ficus aurea, the colonies being so crowded 

 that nothing can be said of the nature of the galleries. The 

 sexual differences are rather feeble : in the male the supraorbital 

 ridge is stronger and more acute, the antennal club larger, and 

 the hairs of the funicular joints are longer. 



The species represents a group of Hylurgini (Le Conte) new 

 to our fauna, viz., the Camptoceri (groupe Camptocerides, 

 Lacordaire ; subtribus Camptoceridae, Chapuis) , which is well 

 characterized by the form of the antennas and anterior tibiae. 

 The genus Loganius was* very briefly diagnosed by Chapuis in 

 his Synopsis des Scolytides, but a full description has never been 

 published, so that it is not possible to decide whether or not the 

 above-described species is congeneric with the type of the genus 

 L. flavicornis from Cumana, Venezuela. 



The insect resembles some of our smaller species of Scolytus 

 not only in superficial characters, but also in the structure of the 

 front tibiae, and should be placed at the head of the Hylurgini, 

 immediately following the tribe Scolytini. In the nature and 

 arrangement of the funicular hairs there is an unmistakable re 

 semblance between Loganius ficus and Thysanoes fimbricornis. 



Mr. Ash mead spoke briefly of the remarkable subtropical 

 fauna of Florida, and Mr. Schwarz defined accurately the Antil- 

 lean faunal belt. 



The following notes on Hymenoptera by Mr. William H. 

 Patton were read by the Secretary :

The markings vary in position and extent without any varietal 

 differences worthy of a separate name. 



*In freshly hatched individuals the inner and outer edges of the front 

 tibiae are fringed with a row of fine setae, which are usually lost in the 

 older specimens, while the setae on the middle and hind tibiae are stronger 

 and more persistent.
