SOLENONOTUS.—SCOLOPOSCELIS. 300 
” 
3. Solenonotus nigromarginatus, n. sp. (Tab. XIX. fig. 31.) 
Rather broad, shining, depressed, the flattened apical portion of the scutellum opaque and the elytra dull; 
finely pubescent and also clothed with a few long erect hairs, the abdomen with several very long bristly 
hairs at the apex; piceous, the elytra testaceous or stramineous, with the cuneus and embolium to a 
greater or less extent black, and the membrane hyaline or flavo-hyaline; the antenne, rostrum, and legs 
testaceous, the femora piceous or fuscous. Head considerably broader than long, smooth, the eyes rather 
large ; antenne moderately long, joints 1 and 2 stout, 3 and 4 very slender, 2—4 nearly equal in length, 
2 thickened outwards and about three times as long as 1; rostrum extending to a little beyond the 
anterior cox. Pronotum trapezoidal, short, somewhat deeply emarginate at the base and very finely and 
obsoletely margined at the sides, more or less distinctly sulcate down the middle of the anterior Jobe, the 
latter almost smooth, the posterior lobe depressed on the disc and transversely rugulose. Elytra almost 
smooth. Orifice of the metastethium long, curved forward externally, and reaching to near the outer 
edge of the metastethium. Legs rather short, the femora incrassate, the anterior and posterior pairs 
very stout. 
Length 2-23 millim. (¢ 9.) 
Hab. GuatEMaLA, El Reposo, Las Mercedes, Pantaleon (Champion); Panama, Bugaba 
(Champion). 
Numerous examples, all from the Pacific slope. This insect has very much the 
facies of a Prezostethus, the antenne being formed as in that genus, but the wings are 
destitute of the hamus in the cell. 
SCOLOPOSCELIS.

Reuter, Monogr. Anthocorid. pp. 114, 151. 
Dr. Reuter includes this genus in his division Xylocoraria, which are without a 
hamus in the cell of the wings; but in the American species, as well as in one of the 
European forms, the hamus is often present. Four species are known, three of which 
are Palearctic.

Hab. Nortu America, Texas ! 2.—GuateMaLa, San Gerdénimo (Champion). 
Four specimens, agreeing with the Texan type now before me. 
Fam. CERATOCOMBIDZ. 
Of this family a single species only is known to me from Central America. None 
appear to have been recorded as yet from within the limits of the United States. Nine 
species, belonging to six genera, have been noticed by Prof. Uhler from the Antillean 
islands of Grenada and St. Vincent, and it is therefore probable that others will 
eventually be found on the Isthmus of Panama. 
* The insect is narrower than represented by our artist.
