HERMAPHRODITE SPECIMEN OF PODALIRTUS RETUSUS, L. 

 BV THE KEV. P. D. MOUICE, M.A.., F.E.S. 



The recent work of v. Diilla Torre and Friese on " Hei'maphrodile 

 and Gynaiidromor[)hous Hyuicnoptera " (Innsbruck, 1899) contains 75 

 quoted and 5 new instances of this phenomenon. Two of these (viz., 

 "■iB—AiitJiojjJiord retiisa, L.," and "' 4<i5—Anthophora (icervuruiii, L.") 

 are derived from notices by Smith and 8huckard, and tliese seem to 

 be the' only cases yet recorded of hermaphroditism in the geiius 

 Anthoj)hora, or, as it seems we should call it, Podalirius. 



At a Meeting of the Entomological Society of London in October 

 last I exhibited a very curious hermaphrodite specimen of Podalirius 

 (= Anfhophora) refusus, L., which I had captured on April 2Gth, 

 1900, at Ottershaw, between Woking and Chertsey. The characters 

 of the two sexes are blended in it after a somewhat intricate faishion, 

 which it may be worth while to record in detail, as it differs a good 

 deal from that described in the specimens aboA'e mentioned. I give 

 also camera-! ucida sketches of the genitalia, which as will be seen are 

 very cui'ious. The other characters of the insect I do not figure, as 

 I hope to convey a sufficient idea of them by simple description. 



The general external aspect of this insect is that of a female, but 

 it has the following male characters : — 



Mead. — Left half of labrum, and left half of clypcus towards its apex, yellow, 

 and clothed with silvery hairs. A fulvous tuft between the ocelli and the insertion 

 of the left antenna, and a paler tuft below it (at the base of the clypeus), left half 

 of the head clothed posteriorly above with fulvous hairs, below, and along the 

 mandible (posteriorly) with wliite. 



Thorax, &c. — Region sun-ouuding the right tegula clothed witli fulvous hairs. 

 Right intermediate leg with dilated and flabellated metatarsus (the character rather 

 less developed than in a normal g ) . 



Abdomen. — Right half (nearly) of 2nd dorsal segment clothed with fulvous 

 hairs and with a paler apical fascia. A less distinct pale fascia on the following 

 segment. 



Genitalia. — One stipes and one sagitta only present — the left (fig. 2). The 

 right half of the armature appears to be ? , con- 

 sisting of a distorted aculeus and its sheatiis 



(fig. 1). 



I can only find six exposed dorsal and ventral 

 segments on either side. The 5th dorsal has a 

 singular appearance, its apex being densely pilose 

 on the left ( ^ ) side and nearly naked on the 

 Fig. 1. Fig. 2. other. The 6th dorsal bears the usual pygidial 



field. The 6th ventral seems to be divided longitudinally into two lobes, the right
