from its female in the particulars < 49 > of the prothorax he pre- 

 sumed to be specific. On the co-type and other specimens of 

 boisduvali the elytra have an obscure bluish gloss ; on simplex 

 they are deep black (Champion described the elytra as bluish- 

 black, but they very seldom have the least trace of blue). 

 The punctures on the elytra of both forms are much denser 

 than on the head, where they are somewhat denser than on 

 the prothorax ; on the latter they are subject to a certain 

 amount of variation. 



DOHRNIA EREMITA, Blackb. 



The male of this species has the head slightly larger than 

 in the female, with more prominent eyes and longer antennae, 

 prothorax smaller and more strongly sculptured, and tip of 

 abdomen very different. Both sexes superficially strongly 

 resemble the female of miranda, but may be at once dis- 

 tinguished by the basal joint of the antennae; in the female 

 of miranda this joint is quite as long as the distance between 

 the eyes. In the present species it is scarcely half the distance 

 between the eyes. 



DOHRNIA BIFOVEICOLLIS, n. Sp. 



9 • Black; head in front of eyes (but not labrum, which 

 is of a shining black), prothorax, scutellum, under-surface 

 (except metasternum, abdomen, and a spot on the side of each 

 eye), legs (parts of tarsi and tips of tibiae infuscated), most 

 of palpi, and under-parts of from two to four basal joints 

 of antennae flavous. Moderately clothed (more sparsely on 

 the head and prothorax than elsewhere) with short, pale, 

 depressed pubescence. 



Head moderately convex ; with dense and rather small 

 but sharply-defined punctures. Eyes large and prominent, 

 feebly notched in front. Antennae moderately long and not 

 very thin, eleventh joint distinctly longer than tenth, and 

 semidouble: Prothorax lightly transverse, sides dilated near 

 apex; on each side towards apex with a large deep excavation, 

 a narrowly-impressed line close to apex, and another close to 

 base; with rather small and irregularly-distributad, but 

 sharply-defined punctures. Elytra much wider than pro- 

 thorax, parallel-sided to near apex ; each with two rather 

 feeble discal costae ; with very dense and small punctures. 

 Claws somewhat swollen near base. Length, 5-6 J mm.

 on others.
