little longer, pointed. Mesonotuni Avith 2 furrows, converging and al- 

 most meeting at the base of the scutelhim. AViugs hyaline, the eosta 

 and stigma brown, the other veins pale. 



Habitat. — Washington, D. C. 



Type $ in National Museum. 



Reared by Dr. C. V. Eiley, at Washington, D. C, Jnly 23, 1883, from 

 Typhlocyba sp. occurring on Celtis and elm. 



PHORBAS Aslini., gen. nov. 

 (Type /'. /rt/icej>s Asian., rf.) 



Head broadly transverse, wider than the thorax, but not especially 

 thick through antero-posteriorly, and when viewed from in front 

 rounded; eyes oblong oval, pubescent; ocelli 3, triangularly arranged, 

 neither especially small nor very close together. 



Antennte 10-jointed, thick, filiform, not longer than the thorax, pu- 

 bescent, the scape only a little longer than the first fiagellar Joint. 



Maxillary palpi 5-joiuted. 



Mandibles 3-dentate. 



Thorax as in Aphelopus, but without distinct parapsidal furrows, the 

 ])rothorax only slightly visible from above. 



Front wings with a lanceolate stigma, two basal cells, and an open 

 nmrginal cell. 



Abdomen subpetiolate, oval. 



Legs as in Aplielopus. 



A genus described from a single male specimen, but the lanceolate 

 stigma and 5-Jointed maxillary pali)i will, however, distinguish it from 

 all other males, in the genera in which the males are known. There is 

 a possibility that it may be the opposite sex of my genus Bacchus, as it 

 agrees with it in maxillary, mandibular, and wing characters, but other- 

 wise, in the shape of the head, thoracic, and abdominal characters, it 

 is quite distinct. Of the other genera, it comes nearest to Aphclo^ms, 

 but the widely transverse head, absence of parapsidal furrows, and the 

 lanceolate stigma, sufficiently separate the two. 



The single specimen, described below, was captured in Florida by 



sweeping. 



Phorbas laticeps, sp. nov. 



(PI. V, Fis. 7,<?.) 



S . Length 2""". Robust, black, subopaque, finely shagreened and 

 sparsely pubescent. Head transverse, much wider than the thorax, the 

 occiput very wide, not at all emarginate. Eyes prominent, oval, pu- 

 bescent. Mandibles 3-dentate, rufous. Antenna' 10-jointed, extending 

 to the teguhe, pubescent, the scape longer than the first fiagellar Joint, 

 the flagellar joints, except the i)enultiniate, about of an equal length, 

 twice as long as thick, the last pointed, the i)enultimate only li times as 

 long as thick. Me.sonotum with two faint furrows; scutellum smooth.
