Tl-IE ORTHOPTERAN GENUS TIU~IEROTROPIS.

BY JERO~IE i\IC:";EILL, STAKFOHD U:'\1\'EHSITY, CAL.

I ha 1·e recent] I" finished a revision of Trimerotropis Sti\ l and as its publication is likely to be somewhat delayed it ha~ been thought best to publi,-,h the key with brief notes on the most important synononw and the localities of the species. Through the kindness of the Nation:tl l\Inseu m, Dr. Scudder and Dr. Bruner I have been :1ble to study the type" or typical specimens of all the species del'<.:rihed in this country

•

except <•nly Tr. tlwlassica. The type of this species should be in the National J\Iu,eum but I have not been able to find it there. I have not been able to examine Saussure's types but \Vith a few exceptions I have sat isf:1ctorily determined his species. The genus is one of the large~t and most difficult of Orthoptera hut with a single exception it contains species of little economic importance .
