106 PROF. M. BEZZI. 



The species which I have in 1913 interpreted as zonatus must be renamed, and I 

 propose for it the name of correctus, n. n. The true zonatus, as here defined, is very 

 like typical ferrugineus and probably only a variety of it, being distinguished by the 

 different wing pattern. The wings have no dark costal border, but only a well defined, 

 isolated black spot at the end ; the first basal cell is altogether hyaline ; the anal 

 dark streak is wanting. Wing characters of male as in ferruginefis. Very 

 characteristic for the species is the white-dusted band at the hind border of the 

 second abdominal segment. The frontal spots are not distinct, and the facial black 

 spots are much smaller than those oiferrugineus. 



I have seen some specimens of the present species which show an abnormal tendency 

 to have three or four scutellar bristles, but it is interesting to note that these super- 

 numerary bristles are always apical, not basal. 



I have seen numerous specimens, including paratypes of Rivellia persicae, 

 Bigot, in the Indian Museum, labelled " the Ranchi peach-pest " ; Pusa, Bihar, on 

 peach (Prunus persica), vi.l914, on fig (Ficus sp. cultivated), iv,1914, on sapodilla 

 {Achras sapota), vii.1914, and from ripe Bael fruit {Aegle marmelos), viii.1914 

 {T. B. Fletcher) ; Santikoppa, North Coorg, from fruits of Careija arborea, v. 1914 

 (T. B. Fletcher) ; Amnoha, Moradabad, on mango fruits, vi,1914 (T. B. Fletcher); 

 Pachmarhi, 3,500 ft.. Central India, in peach fruits, vi.vii.l913, and Nagpur, in 

 white gourd {Lagenaria vulgaris), viii.1913 (Ratiram) ; Taru, Peshawar Dist., bred 

 from peach, viii-ix.l914 (T. B. Fletcher). 



8. Chaetodacus tubercuSatus, sp. nov. 



The present species takes an intermediate position between the preceding, with 

 which it has in common the two separated facial black spots, and the following one, 

 Mdth which it corresponds in the colour of the body. Eminently characteristic of it 

 are the wholly yellow hind tibiae, which have a strong tubercle on the outside, before 

 the end. 



(^. Length of body, 6 mm. 



Head as in correctus, with the same yellow bristles and only two pairs of lower 

 fronto-orbitals, but the facial black spots are rather broad, rounded or ovate, larger 

 than in zonatus, but not at all concurrent towards the middle ; frontal dark markings 

 less distinct. Thorax wholly black, also on the pleurae and on the breast ; on the 

 back it is greyish dusted, and around the humeral calli it is a little reddish ; besides 

 there are the following yellow markings : — humeral calli, a streak on each side behind 

 the suture, a broad mesopleural band encroaching above on the sutural callus and 

 prolonged below with a spot on the sternopleura, and two contiguous h}'popleural 

 spots. Scutellum entirely yellow, with narrow black base ; mesophragma black, 

 with a dark reddish, longitudinal middle stripe. Halteres pale yellow. Thoracic 

 and scutellar bristles of a dark yellow colour, the scapular well developed, the anterior 

 supra-alar strong, the pteropleural weak. Abdomen black, minutely punctulate, 

 with short grey pubescence ; third segment with black cilia ; first and second seg- 

 ment more or less yellowish on the posterior half, and therefore at the base of the 

 abdomen there is a more or less broad transverse yellow band, divided into two parts 

 by a black transverse line, the posterior part being a little whitish. Venter and 

 genitaha black. Legs rather short and stout, entirely yellow, even on the coxae,
