THREE MYRMECOPHILOUS NOTES. 137 



My friend, Mr. E. Ernest Green, on his return from Ceylon, gave 

 me a number of tubes with ants in spirit, and one of these contained a 

 colony of Motwiiioriiin) fioricola, comprising some $ 9 , a few (? cT , a 

 very large number of ^ ^ , larvae and pupa9. In this colony I found 

 the above-described curious gynandromorph. 



In 1903 Wheeler described six gynandromorphous ants, and re-,, .. 

 viewed the previously recorded cases, seventeen in number [Bull. Amer. 

 Mas., N. H., 19, 653-683, 11 figs. (1903)], and in January 1914 he 

 again reviews the additional cases that have been described since his 

 former paper. He remarks, "although many thousand ants have since 

 passed through my hands, I have failed to find any additional cases. 

 Other observers, however, have been more fortunate, and have 

 described seven within the past decade" [Amer. Nat., 48, 49-56 (1914).] 



These seven additional cases — three of which were British speci- 

 mens described by me — together with the one now described, will 

 bring the total of the number of cases which have been recorded up to 

 thirty-one. 



II. IlYOBATES BENNETTI, N.S., A SPECIES OF CoLEOPTERA NEW TO 



Science. 



Brownuh-red, elytra, ape.v of abdomen and base of segments, antennae, palpi 

 and legs yellowish, pubescence yellow. 



Head coarsely punctured ; antennae with first joint thick, thicker than in 

 nigricollis, second joint shorter, joints four to ten transverse, eleventh longer than 

 'broad, but shorter than in nigncollis ; maxillary palpi with second joint very little 

 longer than first, considerably thickened towards apex, the whole being thicker 

 .and shorter than in nigricollis ; labial palpi thicker and considerably shorter than 

 in nigricollis. Thorax as coarsely punctured as head, transverse, not much narrower 

 than elytra, shorter than in nigricollis, with sides less rounded, and posterior 

 angles sharper and more prominent. Elytra less coarsely punctured than head 

 and thorax, about as broad as long, shorter and less coarsely punctured than in 

 nigricollis, with humeral angles more prominent and less rounded, pubescence 

 shorter and closer. Abdomen above duller, punctuation closer, at the base of the 

 first four visible segments coarser and closer. 



Underside duller, punctuation coarser and closer, pubescence shorter and closer. 

 Posterior femora somewhat bowed behind middle. 



Long, 3mm. 



This specimen was captured by my friend, Mr. W. H. Bennett, at 

 Hastings, who took it with Lasiiis fuUginosas in Bexhill High Wood 

 in 1907, and I have named it after the captor. 



At the time he thought it must be a new species, and, having sent 

 it on to me, I agreed with him, and forwarded it to Father Wasmann, 

 ■who also expressed the same opinion. It was then sent to another 

 authority on the continent, who stated it was only a small specimen of 

 I. nigricollis, Pk., and there the matter rested. Bennett, now having 

 kindly presented the specimen to me, I determined to study it more 

 closely, and, on finding so many marked differences between this speci- 

 men and specimens of nigricollis, 1 feel justified in describing it as a 

 new species. As it is such a small specimen, the comparisons with 

 niyricollis are, of course, in proportion to its size. The most striking 

 features are the thicker and shorter palpi, Avhich may, perhaps, suggest 

 modification to suit a myrmecophilous life. 



JII. Atemeles emarginatus, Pk., var. nigricollis, Kraatz. [Naturg. 

 Ins. Deutschl., 2, 117, (1858).]
