Family 86. PYROCHROID^E. Head exserted, strongly constricted behind the eyes, which areemarginate; antennas eleven-jointed, inserted before the eyes; pro-thorax narrower at base than elytra; anterior coxce large, conicaland contiguous, cavities widely open behind; intermediate coxceconical, contiguous, posterior coxce transverse; elytra ample, widerthan abdomen; abdomen with jive free ventral segments, a sixthbeing visible in the male; legs long,penultimate joints of tarsi bilobedor dilated, claws simple. This family is allied to the Mela/ndkyidje, but differs in theformation of the head and neck, and the bilobed or dilated. Fig. 77.—Pyrochroa coccinea; larva X f ; pupa X 3.(After Schiodte.) penultimate joints of the tarsi; it includes some forty to fiftyspecies which have been found mostly in temperate or coldclimates (North Europe, Siberia, Northern Japan, and NorthAmerica). Several fine and beautiful species, however, haverecently been found in Burma by Mr. Doherty, and species havealso been recorded from Bengal and Kashmir. They are, inmany cases, comparatively large and conspicuous insects, of abrilliant scarlet colour, or scarlet with a black head, or black witha scarlet prothorax, and are sometimes remarkable for theirstrongly pectinate or ramose antennae. They are usually found XYLOPHILIDiE.—ANTH1CIDJE, 173 under bark, in stumps, or, in hot weather, on flowers andshrubs. The larvae of Pyrochroa are elongate, parallel-sided, flat insects,varying a little in the shape of the thoracic segments and theanal appendages ; the head is
