4. Chilocorus similis Rossi 

 (COLEOPTEEA: Coccinellidae). 



Imago: 3.5-4 mm. in length. Hemispherical, somewhat elongated. 

 Body smooth and shining, black. On the middle of the elitra with reddish 

 spots. Antennae yellowish brown. Abdomen yellowish brown; ventral 

 side of the basal segment has a black spot. Legs black, articulations and 

 tarsus dark brownish. Whole surface of body covered with minute dots. 

 Abdomen and legs covered with pubescence. 



Egg: 1 mm in length. Spindle shaped, turning in color from light 

 yellow to orange in course of development. 



Larva : 6 mm in length. Light greyish brown ; dead black. Thorax 

 and abdomen clothed with black spines bearing dark hairs; five pairs on 

 prothorax, 4 pairs each on the mesothorax and metathorax, 3 pairs each 

 on first to eight abdominal segments. Head and legs black. 



Pupa: Remains within the larval skin exposing its upper surface 

 from inside. Body 3.5 mm in length, reddish brown. 



The species which is known to feed on scale insects of Diaspis, 

 Aspidiotus, etc. were shipped to the United States to serve as an enemy 

 of noxious coccid. But since this lady-bird eats large numbers of young 

 larvae of the white wax insect, it is a formidable enemy of the latter. 

 The imago of this lady-bird passes through the winter and lays eggs under 

 the scale of the scale insect in April. The larvae which feed on noxious 

 scale insects pupate towards the beginning of June are converted into 

 imago, and destroy the larvae of the white wax insects. 



5. Chilocorus tristis Fold 

 (COLEOPTEEA: Coccinellidae). 



Imago: Length 5-6 mm, hemispherical, somewhat elongated and 

 tapering on the end. Black, smooth and shining, on the middle of each 

 elitra are red marking, the margin is merged into black with no particular 

 distinction recognizable. Antennae brown. Ventral surface of tarsus with 

 soft light brown hairs. Marginal part of dorsal surface of thorax and 

 abdomen with a few short hairs.
