rity approaches. The figure will obviate the necessity for a long 

 description, the striking points, to which attention should be 

 directed, being found in the long palpi, the strong bristles and 

 the appendages of the terminal abdominal segment. 



Silpha sorinameusis Fabr. fig. 2.— Color of larva nearly black above, 

 a light yellowish dorsal line, interrupted at the posterior margin of each 

 segment, extending almost the entire length ; the sides of the thorax and 

 abdomen are also bordered with the same color. Beneath yellowish with 

 a few brown markings. The form is elongate, tapering behind, moder- 

 ately convex, last abdominal segment with two straight appendages. 

 Length, in spirits, 19 mm. Head broader at base, sides rounded, front 

 sinuate laterally and emarginate at middle, surface of head rough with 

 large punctures and unequally impressed. Eyes six on each side of the 

 head, a group of four being situated on the dorso-lateral surface behind 

 each of the anntennae and very close to the thoracic margin, the other 

 pair is on the ventro-lateral surface somewhat anterior to the group men- 

 tioned. They are of fairly large size. Antennae inserted near the sides of 

 the head, immediately anterior to the large group of eyes, the basal joint 

 (?) or support of scarcely appreciable length, the others of good size, 

 somewhat bristly and decreasing in length and thickness to the last, which 

 is tipped with a short spine and a few very minute aciculi. Mandibles 

 moderately strong, sinuate on the outer edge, apex acute, internal edge 

 with a tooth near the tip and sinuate. Maxillae with a broad inner lobe, 

 the inner margin with a series of ten articulated spines on the apical half 

 and a brush of bristles near the base, tip with a much larger brush of 

 bristles which extend also for some distance down the outer margin. 

 This margin is armed with two long stout bristles. Palpus four-jointed, 

 borne on a swollen base, the first joint short and thick, the three following 

 more elongate and subequal in length among themselves, the last being, 

 however, more slender and bearing a few aciculi at apex. Mentum some- 

 what obcordate in form, broader before the free end which is sinuate at 

 sides and deeply emarginate at middle, the palpi heavy, two-jointed, the 

 basal joint much the larger, the apical with a few aciculi at tip. The body 

 of the mentum is furnished with short bristles distributed in close array 

 over a pattern shown in the figure. Prothorax broader towards the base, 

 sides somewhat rounded and very slightly sinuate, apex less rounded, 

 angles not marked, side margined, disc with a fine longitudinal median 

 line, surface irregularly rugose. Meso- and metathorax shorter, sides 

 rounded anteriorly and with a subangulation behind ihe middle, surface 

 finely transversely rugose. Abdomen with fine grayish or whitish hairs 

 on the dorsum and composed of nine true segments and a proleg. The 

 first eight segments have a well-marked thin margin, which is rounded 

 anteriorly and acute posteriorly; on the ninth segment this margin is less 

 evident, though present. These marginal pieces are all finely bristled 

 externally and more coarsely at the posterior angles. The appendages 

 which are borne on the ninth segment are straight, two-jointed and spiny,
