122 Dr. H, Scott's Notes on biolor/y of some irupn'lmes and 



since exactly the same structures, arranged in the same 

 general way, are described by Ferris in the larva of E. 

 obsolefa, found under the bark of tree -stumps. Larvae 

 of other Nitidulid genera bear doi'sal asperities of various 

 kinds.* 



Comparison of larvae of E. depressa and E. obso- 

 LETA.^ — The larva of E. depressa agrees in most ])oints with 

 the description given by Ferris of that of E. obsoleta. 

 There are, however, some divergences.' He describes and 

 figures the meso- and raeta-thorax of the latter as larger 

 than the abdominal segments, which in E. depressa is not 

 the case. My material also differs from Ferris' description 

 in the number of ocelli and the number of segments in the 

 maxillary palpi, as stated above. 



VII. Pupa of Epuraea depressa. (Fig. 8.) 



Length (excluding the long spines at the front and 

 hind ends) 3-3'5 mm. Whitish, not enclosed in a cocoon ; 

 furnished with a formidable armament of spines, which 

 are rather broad at the base and taper to a very sharp 

 point. The head bears two short, erect, spines, one im- 

 mediately over each eye, and slightly curved backwards ; 

 these, of course, are not visible in dorsal view. The 

 protJiorax has two long, curved, forward-projecting spines 

 on its front margin. On either lateral margin are 4 short 

 spines ; one on the part of the margin which curves down- 

 wards and inwards tow^ards the eye (not visible in dorsal 

 view), two others before the hind angle, and a fourth 

 almost on the angle (these latter three are visible in dorsal 

 view and shown in fig. 8 a). There are also two long, 

 nearly straight, spines, erect and directed a little out- 

 wards, on the disc just before the hind margin. Each 

 leg has a short, curved, spine at the knee-joint, on the 

 apex of the femur ; these are visible in dorsal view, since 

 the femoro-tibial joints project beyond the outline of the 

 body. Abdomen : the arrangement of spines is best 

 shown in dorsal view. The basal segment bears none. 

 Segments 2-8 have each two spines on either side, these 



* The larva of Pocadius ferrvgineiis— the only otlaer Nitidulid 

 larva to hand for comparison — has 6 dorsal longitudinal series of 

 setae, as well as setae on the lateral inargins. Those of the two 

 mid-dorsal series are borne in groups of three on tubercles. There 

 is no modification of setae into flattened or spatulate hairs.
