The Secretary read the following note from Mr. W. L. Distant : — 



" My friend Mr. F. Moore has placed in my hands for determination 

 a few Hemiptera, which he received from India, with the accompanying 

 notes as to their habits, &c. ; and as little is known of Indian Economic 

 Entomology, especially as far as the order Hemiptera is concerned, 

 I herewith state the results of my examination. 



" Species reported as feeding on the flower-juices of plants of the 

 cucumber tribe : — Hahjo dentnta, Fab. ; Palomena viridisslma, Poda (var.) : 

 Piezoderus riibrofasciatiis, Fab.; Agonoscelis nubila, Fob.; Lygaus militaris, 

 Fab. ; Graptostctkus servus, Fab. 



" Coptosoma cribraria, Fab. Reported as very common on Legumines 

 [Labial, vulgaris, &c.) ; the flower-stalks and flowers in many cases swarm 

 with them, and so continuing until they had reduced all to bare stalks. 



" Bagrada plcta, Fab. Reported as aff'ecting the flower-shoots and 

 flowers of the field mustard [Sinapis dichotoma), on which plant is also 

 found Pachymenis sordidux, Fab." 



The Secretary also exhibited a photograph on behalf of Dr. Fritz Miiller, 

 and read the following note : — 



" I take the liberty of sending you a photographic copy of some 

 drawings of a very curious dipterous insect. The larva is remarkable for 

 having six segments only, each being provided on the ventral side with a 

 complicated disk, by which it firmly adheres to the rocks of rapids. The 

 first segment of the larva is a cephalothorax, comprising the head, thorax, 

 and first abdominal segment of the pupa. The pupa, which is firmly 

 cemented to the rocks, has its antennae, wings and legs free, not adherent 

 to the body. The perfect insect is remarkable for the dimorphism of the 

 females. One set of females agrees in the want of maudibulae and the 

 structure of the oval parts with the males. They are probably honey- 

 sucking. The other set of females are provided with mandibulse, like the 

 blood-sucking females of Culex, Tabanus, &c. In the size of the eyes and 

 the structure of the feet the blood-sucking females differ much less from 

 the males than the honey-sucking females do. I have lately sent to the 

 ' Archivos do Museu Nacional de Rio de Janeiro' a description of this insect, 

 accompanied by seven plates, three of which refer to the highly interesting 

 structure of the larva." 



Paper read. 



Dr. F. Buchanan White communicated Part I. of a "List of the 

 Hemiptera collected in the Amazons by Prof. J. W. H. Trail in the years 

 1873 — 1875." The present paper deals only with the aquatic Hemiptera 

 (Ploteres and Hydrocorisa); twenty-three species and one variety are 

 mentioned, out of which eleven are new. In addition to these, eight of the
