NOTES ON THE STRAWBERRY LEAF BEETLE 

 {GALERUCELLA TEN ELLA LINN.). 



By H. C. EFFLATOUN, F.E.S., M.E.A.C. 



(With 3 Text-figures.) 



Specimens of the larvae of this strawberry beetle, received by Mr F. V. 

 Theobald were given to me to describe and follow out the life-history. 

 The following are some notes I have made in regard to the various stages. 

 It is hoj)ed that, later, fuller details of the bionomics of this insect will be 

 ready for publication. The insects bred in the laboratory of the South 

 Eastern Agricultural College were sent to Prof. Theobald from County 

 Monaghan, Ireland, where they had done much damage. 



LARVA. 



Length, one-eighth to one-sixth inch. Colour, dirty greenish yellow, 

 head black. All the segments of the body, with the exception of the head, 

 pronotum and anal segment, have a pair of elongate, transverse, thickish 

 stripes, the cephalad stripe being larger than the caudad one. The stripes 

 on the meso- and metanota are separated as shown in the figure. The 

 dorsal segments are transversely furrowed. Each segment of the body, 

 with the exception of the thoracic region (pro-, meso- and metanota) have 

 four shining black tubercles on each side. These tubercles vary in size, 

 the largest being near the transverse stripes. The pronotum is free from 

 markings or tubercles and is uniformly dark brownish-grey. The meso- 

 and metanota have two tubercles instead of four on each side; the inner 

 pair are somewhat round, while the outer pair are much larger and some- 

 what crescent-shaped. The terminal segment is brownish-grey and more 

 hairy than the rest of the body. There are three pairs of true (segmented) 

 legs, which are black, on the three first segments of the body. Each'bears 

 two sharp claws. The anal segment possesses a large and simple process 

 or proleg by means of which the larva progresses after the manner of one 

 of the Geometridae. The body is covered with more or less numerous 

 yellow hairs.
