Clypei apex fortius quam in boope reflexo-productus, nonnibil rotund atus. 

 Frons infra oeellum anticum valde turgida, sulco angusto sed profunde itnpresso 

 longitudinaliter divisa. Antennarum articuli intermedii infra in medio ne minium 

 quidcin einarginati. Alarum superiorum vena transverso-cubitalis prima venae 

 bewail (non ut in boope venae recur rent i. prima;) fere parallela ; unde multo minor 

 fit cellnla cubitalis secunda, neque est ea infra (ut in boope) cellulse eubitali primoe 

 latitudine subrequalis sed multo angustior, tertian vero panic requalis. 



Abdominis seginentum primum dorsale erebrius fortiusque subprofunde punc- 

 tatum. Pili abdominis apieales baud albi sed plus minusve nigricantes.

Morawitz describes his tegularis (from Mongolia) as having white 

 tegular, but the rest of his description does not at all suit the present 

 insects. In macula/us, Hud. (" uiaculis callosa, subalari, hunierali, 

 eburneis ") the abdomen would seem to be black, the tegula? are not 

 mentioned. In Miegii, Duf., the tubercles are white, but the tegulre 

 are called nigro-fuscous, and the abdomen seems to be impunctate — 

 at least it is spoken of as simply " laevigatus." Of scapularis, Kohl, 

 also a species with white tubercles, only the ? is known, which makes 

 a comparison of it with my species not easy. But I see no reason to 

 think they are identical. Scapularis $ is described as having an 

 emarginate clypeus, and as resembling hoops $ in the alar neuration 

 and the structure of the antenna? ; the tegulrc do not seem to be white, 

 nor the brow unusually swollen, nor the abdominal puncturation re- 

 markable. After making all due allowance for sexual difference, it 

 still seems unlikely that Pelops can be the missing £ of scapularis. 



The peculiar structure of the frons and the clypeus, the strongly 

 punctured base of the abdomen, and the narrow 2nd submarginal cell, 

 together with the clear ivory-white tegulre and tubercles, make 

 Pelops <$ a very distinct and easily recognised insect. 



Two of its characters (the swollen frons and the neuration) 

 might suggest that we are dealing after all with a Homogambrus ! But 

 that is certainly not so. A. Pelops has the simple mandibles, the dis- 

 tinct round ocelli, etc., and in short, all the essential characters, as 

 well as uumistakeably the fades of an Astatus ; and to that genus 

 beyond all question it belongs. 



I took two males at Olympia (10th — 11th May, 1901) but could 

 find no female. 



The locality has suggested to me the name proposed, the hero 

 Pelops having been specially connected with Olympia (see Pindar's 

 First Olympian Ode). It is also a curious coincidence that both 

 Virgil and Pindar call Pelops " distinguished by his ivory shoulder" — 

 just as is the present insect.
