British Museum, the last-named author has tacitly placed panamensis 

 under Arachnocoris albomaculatus, Scott, but it differs from Scott's 

 species, apart from other characters, by the non-incrassate middle 

 femora, which in albomaculatus are strongly thickened. This might, 

 of course, be a sexual character, but as the types of albomaculatus and 

 panamensis are both males, there can be no doubt that panamensis is 

 a distinct species. Tet the true albomaculatus occurs also in 

 Panama, as I have before me a specimen f rom Tabernilla (Canal Zone), 

 taken by Mr. A. Busck, belonging to the Washington Museum. The 

 following species is so distinct and easily recognised from the others 

 that I describe it, although the type is not in the best condition. 



Arachnocoris torquatus, n. sp. 



Augustus, gracilis, nitidus, piceus, capile testaceo, macula interoculari per cly- 

 peum continuata et lineola transversa inter ocellos piceis, hemelytris dilute livido- 

 testaceis,ad venashic et illic in fuscatis, fascia nonnihil ante angulum apicalem fusco- 

 cinereum corii picea, collari prothoracis, spinula apicali scutelli, macula triangu- 

 lari ad marginem apicalem corii inter fasciam anteapicalem piceam et angulum 

 apicalem, callo parvo ad angulum basalem metapleurse et segmentorum ventris 

 quattuor primorum et ad marginem lateralem segmenti hujus quinti, margine 

 acetabulorum orificiisque eburneis, limbo basali pronoti albido. Caput e latere 

 visum collari et lobo medio pronoti unitis distincte longius, fronte pilis duobus 

 longis tenuissimis prsedita, spatio interoculari superiore oculo uno duplo et di- 

 midio latiore, ocellis inter se et ab oculis seque longe remotis, articulo primo 

 antennarum piceo, capiti seque longo (ceteri articuli desunt), rostro piceo, basin 

 ventris attingente. Pronotum parce subtiliter puberulum, distincte trilobatum, 

 lobo apicali {collari) quam medio dimidio breviore, lobo basali quam medio duplo 

 et dimidio longiore, subtilissime et remote ruguloso, impressione inter lobos medium 

 et basalem retrorsum parum curvata. Scutellum apice in spinam brevem semi- 

 erectam productum. Hemelytra ( £ ) apicem abdominis paullum superantia. 

 Pedes intermedii fusco-testacei, coxis, trochanteribus, basi et annulo angusto sub- 

 apicali femorum, apice tibiarum tarsisque piceis ; femora sublinearia, hand 

 incrassata ; tarsi longi, triente tibiarum paullo longiores. (Pedum anticorum et 

 posticorum solum coxae picese restant). Long. $ (sine hemelytris) 3.5 mm.

This species, like A. simoni, Bergr., was discovered by E. Simon, 

 the well-known Araclmologist. The members of this genus are said to 

 live in society with spiders, and they resemble somewhat in shape and 

 colour certain narrow myrmecoid species of the Araneid family Salti- 

 cidse. Six species of Arachnocoris have now been recorded, and I have 

 seen another from Trinidad which will be described elsewhere.
