HALTICINtE. 



depressed on the vertex, sloping in front, and with the upper 

 surface sparsely covered with stiff brownish hairs ; antennae 

 minute, three-segmented ; labruni distinct ; mandibles four-toothed. 

 The prothorax is broader than the head, its dorsal surface covered 

 with a strongly chitinised transverse plate. The meso- and meta- 

 thoracic segments are alike, the latter being very slightly broader 

 than the former. There are three pairs of well-developed and 

 strongly chitinised thoracic legs ; each leg consists of three 

 segments and ends in a minute but strong claw. 



The dorsal and ventral surfaces of the body of the larva bear 

 several longitudinal series of spots and patches arranged as 

 follows : as seen from above there are five longitudinal rows, one 

 median and two on each side ; the median row consists of 

 short, transversely elongate patches, there being on each seg- 

 ment two, of which the posterior is smaller than the anterior ; 

 the inner and outer dorsolateral rows are composed of round spots ; 

 in the inner dorsolateral rows these are arranged somewhat 

 irregularly, the posterior spot on each segment being placed nearer 

 the middle line than the anterior one, while in the outer dorso- 

 lateral rows the two spots on each segment are placed one behind 

 the other in a longitudinal series. Thus on the dorsal surface of 

 each segment of the body (except the prothoracic and the anal) 

 there are ten patches, the two transverse median ones and eight 

 round ones placed four on each side. Viewed from beneath each 

 segment (except the anal) is somewmat produced conically on each 

 side, with the apex of the cone truncate and ending in a patch ; 

 these patches form on either side of the body the lateral longi- 

 tudinal series. Finally, on the ventral surface there are five 

 longitudinal rows of patches, the median being composed of a 

 single short, transversely elongate patch on each segment, while 

 the outer series are made up of round spots, regularly arranged, 

 a single spot of each inner and each outer ventrolateral series on 

 either side of every segment ; the spots of the outer ventrolateral 

 rows are placed on the apices of slight conical elevations. On the 

 ventral surface, therefore, there are, in each segment, five patches. 

 All the patches, dorsal, ventral and lateral, are only strongly chitin- 

 ised areas, bearing fine brownish hairs which give the larva the 

 appearance of being sparsely pilose. There are nine pairs of 

 spiracles, one thoracic and eight abdominal. Those of the thoracic 

 pair are situated laterally on the mesothorax. Each abdominal 

 spiracle is placed laterally between the two spots, on each segment, 

 of the outer dorsolateral longitudinal series. The thoracic 

 spiracles are larger than the abdominal. The ninth and anal 

 segments have no spiracles.

The following description is taken from two examples in the 

 British Museum preserved in alcohol, one of which is 5 J mm. 

 long and the other 5 mm. : — The larva is elongate and consists of 

 thirteen segments, including the head, the three thoracic, and
