behind the base of the antennae. The mouth parts are proportionately 

 very small, and so sunken that they are difficult to dissect out. The 

 figure will render detailed description unnecessary. The maxilla? 

 in the figure are separated from the labrum: naturally, they are bent in- 

 ward above, so that only the palpi are visible. The maxillae are rather 

 sparingly clothed with rather thick bristles diverging to all sides; the pal- 

 pi are three jointed, the basal joint very thick and short, the second still 

 shorter and not so thick, the 3d longer than the other two combined and 

 much more slender. The labial palpi are two jointed, the terminal joint 

 obliquely truncate. The head is equally and somewhat sparsely covered 

 with punctures from each of which arises a bunch of hair spreading fan- 

 like toward the tip, as shown in the figure. The lateral appendages are 

 densely clothed with the same fan-like hair tufts, inserted also in distinct 

 punctures. The pro-thorax above is covered in the same way, except 

 near the base and in the depressed central furrow. The meso-, and meta- 

 thorax have on each side a somewhat depressed, harder, more shining 

 scute or plate, also punctured and furnished in the same way with hair 

 tufts. The abdominal segments except the 8th and 9th have each two 

 smaller, ovate scutes of the same nature, each side of the middle. On 

 the 8th segment the scutes are confluent, and cover a greater part of the 

 surface. The 9th segment is equally punctured and furnished with 

 spreading seta;. 



The segments are well marked, the sutures being deep, so that when 

 the insect is placed flat, they look like deep incisions, the sides declivous.
