among the stems and blades of grass, and is then extremely difficult to 

 find. Head slightly narrower than the body, the 2nd segment having 

 a conspicuous and almost spherical tubercal on each side, the effect of 

 which is greatly to increase the apparent breadth of this segment, 

 making it appear much broader than the head ; these tubercles emit long 

 projecting hairs: the 3rd and 12th segments have each a mediodorsal 

 erect compressed tuft of hairs, that on the 3rd segment is double and 

 erect, that on the 12th single and inclining backwards. Colour of the 

 head gray, with longitudinal black stripes, which approach on the 

 crown but recede from each other on the face ; 2nd and 3rd segments 

 orange on the back, the double dorsal tuft on the 3rd having the 

 anterior portion black, the posterior portion orange, the remaining 

 segments with a mediodorsal series of blue-gray spots, each irrorated 

 with minute black specks and alternating with pairs of black spots, the 

 naiTow interstice between each pair being bright orange: exterior to 

 the mediodorsal blue series is a series of orange s})Ots, and exterior to 

 this a mixed series, blue-gray, black and orange, the arrangement of 

 the colours in indistinct oblique lines ; the spots below this are 

 orange : ventral surface, including the claspers, orange, with a medio- 

 ventral series of black markings : legs nearly black. After having 

 hybernated at the roots of grasses during the whole of the inclement 

 season, the larva may again be seen in the spring sunning itself on the 

 culms, but remaining during the day in less exalted situations, prefering 

 those ditches so often without water by the side of hedge-rows, yet 

 abounding with dew-drops, to which these larva3 may often be observed 

 to apply their mouth and imbibe the transparent fluid slowly, sedately 

 and with evident enjoyment, a practice whence probably originate 

 the names of "drinker" and "potatoria:" this propensity to indulge 

 in drink may readily be tested in the breeding-cage by dropping water 

 near the creature's head, when it will turn to the seductive beverage, 

 and enjoy it exactly as when at liberty. The larva is full fed during 

 the first and second weeks in June; it is then more than two inches 

 and a half in length, and thick in proportion: when annoyed it rolls 

 itself in a most compact ring and falls amongst the grass, where, how- 

 ever, it is scarcely likely to escape observation on account of its large 

 size. Head not so wide as the 2nd segment, which is dilated on each 

 side laterally by the presence of two tubercles, of which the upper is 

 the more preminent, the lower broader and less conspicuous ; body 

 very convex above, rather flattened beneath ; it has a mediodorsal tuft 

 of long converging hairs on the 3rd and another on the ]2th segment; 

 the first of these is erect, the second obliquely directed backwards ; on
