200 ALBATROSS EXPLORATIONS, INSECTS HOWARD. 



Family LOCUSTIDiE. 

 Stenopelmatus chilensis .' Sauss. 



A single male specimen of a large, cricket-like Locustida, from Lota, 

 Chili, appears to belong here. The structural character of the pres- 

 ternum will, however, necessitate its removal from that genus as limited. 



Family ACRIDIlDvE. 



Bufonacris terrestris Walk. 



The most remarkable orthopterous insect among the lot is the large 

 wingless Bufonacris terrestris of Walker. Not only is it of interest on 

 account of its odd appearance, but also from the fact of its having been 

 recorded a second time from the Straits of Magellan. Saussure, in his 

 "Additamenta ad Prodromum CEdipodiorum " (p. 1G0, foot-note), dis- 

 credits Walker's citation of the habitat of this locust. It is a barren 

 ground form, and is closely allied to our genus Haldenianella. Its 

 occurrence at a point so widely removed from the subtropical region 

 certainly is an anomaly. Four specimens from Gregory Bay. 



Another exceedingly interesting form from Gregory Bay is repre- 

 sented by six specimens of a small Truxalid belonging to a genus very 

 closely related to Oxycoryphus in its general appearance, but differing 

 greatly from that genus in being entirely apterous, and in having the 

 body ridged or corrugated as in the genus Phrynotettix Sauss. among 

 the Eremobites. 



HEMIPTERA. 



Family PENTATOMID.E. 

 Ditomotarsus hyadesi Signoret, Aim. Soc. Ent. Fr., 1885, p. 64. 

 An immature male specimen from Sandy Point. 



Family ARADID.E. 

 Isodermus patagonicus Still (Meziral), Eugenie, Resa, Ins., p. 200, No. m. 



One specimen, a male, was collected at Sandy Point. It has fully 

 developed wings. 



NEUROPTERA. 

 Family ODONATA. 

 .Sjschna diffinis Ramb., Hiatoire des Neuropt6res, 1842. 



Two specimens of this species were caught at Island Harbor, Pata- 

 gonia. 



One specimen collected at Latitude Cove belongs to the genus Diplax. 

 At Mayne Harbor, Patagonia, was taken a Libellulid pupa. 



Family LIMNOPHILID.E Ramb. 1842. 

 Halesus hyadesi J. Mabille, Mission Scientif. du Cap Horn, 1888. 



One specimen captured at Gregory Bay. Above named French expe- 

 dition in 1883 records also only one specimen (from Orange Bay), and
