A new species of Stirogaster Jak. from Iraq(Heteropt., Reduv.)BYW. E. CHINA, M. A.(London)The genus Stirogaster was founded by Jakowleff 1 in 1876 to holda single new species, S. fausti, collected by Faust and Christoph atKrasnovodsk, Transcaspia. The genus was described in Russian sothat it is not out of place here to draw attention to the generic diffe-rentiation from Oncoaphalus given by Jakowleff 2:Oncocephalus Burm.First antennal segment short, halfthe length of head, one third thelength of second segment. Eyesonly slightly convex, point like,separated beneath the head by abroad space. First rostral seg-ment shorter than second, notreaching the anterior margin ofthe eye. Pronotal carinae obscu-re. Anterior femora unarmed.Stirogaster Jak.First antennal segment twice as longas the head and of the same lengthas second segment. Eyes strong-ly convex and almost contiguousbeneath the head. First rostralsegment longer than second, ex-tending somewhat beyond the an-terior margin of eye. Pronotalcarinae distinct. Anterior femoraarm ed.In 1893 Jakowleff 3 described a further especies S. herzi, collectedby O. Herz in Northern Persia, but this has since been shown be con-generic \vith Oncocephalus by Kiritshenko 4 who recorded it fromWestern Transcaspia and associated it with O. obsoletus Klug andO. impictipes Jak.Twenty years later Horvath 5 described a third species S. deserto-rum, collected by Dr. Ernst Hartert in Southern Algeria.

He writes «pronoto latitudine sua basali dimidio longiore».This must be the result of an optical illusion, not of actual measurement.1\\\>,„:„0,01outtatige100180A NEW SPECIES OP «STIRO(lASTER» JAK PROM IRAQ	 127excepting lateral teeth); lateral carinae and dorsal carinae of posteriorlobe definitely granulate; posterior lobe about 1/2 longer than anteriorlobe (45 : 30); humeral angles not or feebly prominent, anterior lateralangles produced into pale tooth.
