(vi) Colleoptera.—(1) A Oetonid beetle—Clinteria awronotata— 
was collected by me froma bunch of partially faded coffee flowers. 
Probably it feeds on the anthers and stigmas: but I do not think it 
has much imporiance as regards the fertilization of coffee flowers. ° 
(2) A Nitidulid of small size was collected from inside the 
corolla of a coffee flower. ‘ 
(vii) Diptera Syrphide—three different kinds were noted on 
coffee flowers :— 
(1) Syrphus sp. (?} very much like the Syrphus found on Aphis 
in the plains. This was noted on three different occasions on coffee 
flowers, where the pollen was licked or scraped up with the tip of its 
tongue from the anthers and later on the style was similarly treated. 
(2) (?) Eristalis sp. A large fly resembling a bee to a certain 
extent. It was only once observed by me on coffee flowers—on which 
occasion I noticed it brushing pollen up with the tip of the tongue, 
visiting all the anthers by turn. It also licked up the surface of the 
stigma and later thrust the proboscis down the corollar tube for the 
nectar. Certainly a useful insect if present in sufficient numbers. 
(8) Another Syrphid found also on 4 flower on one occasion. 
(4) Muscidae : A fairly large fly—once noted on aflower— 
thrusting the proboscis down the corolla--apparently after nectar. 
(viii) Hemihtera— Pyrrhocoridae (1) Serinetha abdominalis.—This 
bright orange-yellow bug was notedin large numbers in some coffee 
estates. Usually they were found either on coffee bashes or on fallen 
leaves on the soil. Some were noted on coffee flowers as well, but, as 
far as I could observe, they made no attempt either to seek the nectar 
or to suck out the sap of flowers. , 
(ix) Aphide, (2) Aphis—About five specimens of Aphis were 
found on a single unopen flowerbud. They were tended by a species 
of Cremastogaster. 
“4. It is quite possible that, in addition to the insects enumerated 
above, there might have beena number of insects with decided flower- 
visiting habits that might have escaped my observation. Especially is 
this likely to be the case with moths and other nocturnal insects at 
which time my observations are confessedly scanty. Nevertheless, I 
feel pretty certain that coffee flowers (setting aside the probability 
of wind-fertilization) are in the main fertilized by the action of the 
day-flying visitants of flowers. Of the list of about 29 insects enumer- 
ated by me in this report, the really important ones are certainly the 
following :-— 
a The three honey-bees— Apis indica, Apis dorsata and Apis 
ored. 
(2) Xylocopa tenuiscapa and 
(3) Cephonodes picus. 
_ “5, Of the three honey-bees, it was only 4 pis indica that was found 
fairly abundant. Apis florea was present in but scanty numbers while 
Apis dorsata was absent altogether in some estates I examined. In the 
cotfee flower the pistil is very elongate and the stigma stands well 
separated from the anthers, so that when Apis indica and Apis florea 
visit the flower they are unable—whether while seeking nectar or
