from Mexico. From the quite inadequate description it is 

 impossible to say to what genus it belongs, but it is very un- 

 likely that it is an Acanthosoma.

 Repipta spinosa Fabr. 



Mr. Van Duzee has communicated to me specimens of this 

 (or a very closely allied) species. In describing the types in 

 his " Hemiptera Fabriciana " Stal placed Zelus spinosus Fabr. 

 and sexdens Fabr. in the genus Repipta Stal, but later, when 

 the types were not before him, he removed them to the 

 genus Corcia Stal, apparently with some hesitation. They 

 are, however, much better placed in Repipta. 



Diaditus pilosicornis n. sp. 



Testaceous, membrane and inner part of corium pale grayish ; the 

 ocelliferous tubercle, the rostrum, two median pronotal vittse coalescing 

 on the anterior lobe ; a sublateral basal streak to scutellum ; an abbrevi- 

 ated claval streak ; a streak near the inner apical angle of the corium and 

 a shorter outer streak in front of the discoidal cell ; two somewhat obscure 

 longitudinal fasciae to the meso- and metapleura ; two elongate spots, the 

 posterior of which is shorter, to the lateral margins of the abdominal seg- 

 ments, and a sublateral ventral vitta, fuscous ; a large triangular poste- 

 riorly sinuated spot on the discoidal cell ; an irregular abbreviated basal 

 streak on the inner basal cell of the membrane ; a small basal spot and a 

 broad vitta, sinuated anteriorly and strongly narrowing posteriorly, on 

 the outer basal cell of the membrane, very close to the external margin, 

 velvety brownish black ; the other parts of the membrane mottled with 

 pale fuscous ; apex of femora and of tibiae and the tarsi infuscated ; head 

 with the apical processes starting from a common base, somewhat re- 

 flexed, not quite reaching the middle third of first antennal joint, sepa- 

 rated by a very narrow subparallel interstice, with the internal margin 

 straight and the external margin distinctly longitudinally convex ; ocelli 

 placed on the outer side of a raised, rounded tubercle, which is longitu- 

 dinally sulcate in the middle ; interocular space on the underside some- 

 what broader than the rostrum ((^) ; first joint of antennae a little longer 

 than the distance between the interocular furrow and the apex of the 

 antenniferous tubercle ; glabrous ; second joint twice as long as first, 

 longly erectly pilose ; third and fourth joints short, fineh pilose ; fourth 

 longer than third ; pronotum rectangular at apex, with two obtuse keels 

 somewhat diverging backwardly in the hind lobe ; lateral angles acute, a 

 little raised and distinctly prominent ; scutellum horizontal at apex ; 

 hemelytra almost reaching the middle of the last dorsal segment (cJ 1 ); 

 abdomen ((^) with the last dorsal segment rounded, rather broadly and
