OF WASHINGTON. 329 



announce to-night the discovery of a new species, in this remark 

 able genus, in our fauna, made by one of our members, Mr. E. A. 

 Schwarz, last spring in Utah. 



The genus is evidently an ancient phylogenetic type, now nearly 

 extinct, of the family Reduviidce^ remarkable for having the elytra 

 entirely membranaceous with a distinct venation, not unlike cer 

 tain saw-flies, in having greatly swollen anterior legs, the fore 

 tarsi being 2-jointed, whilst the middle and hind tarsi are 3-jointed. 

 It will not fit into any of the subfamilies of the Reduvitdce, as 

 defined by Stal, and will form the type of a new subfamily, which 

 may be known as the Enicocephalincz. , 



Prof. Westwood says : "The very remarkable head, thorax, 

 fore legs, and hemelytra distinguish these curious insects, not 

 only from the remainder of the extensive family of the Redui)iid<z, 

 but also from every other Hemipterous group." In this I quite 

 agree. It appears to me as though the affinitives of this rare 

 genus were equally divided between the Reduviince, Salyava- 

 tince, and the Stenopodince, and I should place it between the 

 Reduviincc and the Salyavatince ; the latter not represented in 

 America. The species collected by Mr. Schwarz in Utah is 

 exhibited to-night, and below I give a brief description, naming 

 it sckwarzti, in honor of its discoverer.* 



Enicocephalus (schivarzii Ashm. MS., olimj culicis Uhler. <$. 

 Length 2.8 mm. Rufo-piceous ; anterior lobe of head blackish ; rostrum 

 and anterior legs, testaceous ; tylus, middle and hind legs, and abdomen 

 pale flavo-testaceous ; elytra membranaceous, subhyaline. 



The whole insect is pilose. Head as long as the pro and meso-notum 

 united, with a strong transverse constriction behind the eyes, the posterior 

 lobe thus formed being a little shorter than the anterior lobe, thicker and 

 sub-globose; the ocelli large, red, placed at the anterior margin; eyes 

 prominent, large, round, and black. Rostrum short, 3-jointed, the second 

 joint a little more than twice the length of the first; the last joint acute, a 

 little longer than the first. Antennae 4-jointed, the first the shortest and 

 stoutest, the second and last about equal, the last being fusiform, the third 

 cylindrical, a little longer than the second. Thorax depressed, anteriorly 

 subtrapezoidal, the collar distinct, short; mesonotum divided at its basal 

 third by a transverse furrow into two lobes, the anterior lobe being two- 

 thirds the length of the posterior, the lateral margins arcuate; posterior 



*Since this was read a paper by Prof. Philip Uhler has appeared in a late 

 number of Transactions of the Maryland Academv of Sciences, in which 

 is described an Hemipteron, under the name Hymenodectes culicis (n. g. 

 and n. sp.) and what is evidently the same insect. It appeared to me that 

 the insect from Utah scarcely differed sufficiently from a typical speci 

 men of Enicocephalus from St. Vincent to warrant the erection of a 

 new genus ; but in this Prof. Uhler is much more competent to decide 

 than myself. The specific name proposed by me must fall.
