To this I refer doubtfully two specimens, neither of them verv perfect, 

 which appear to belong together, and to represent an insect allied at least 

 to Cratoparis and of about the size of 0. huiatus Fahr. It appears to have 

 a short rostrum, a moderately small but rather tumid head with circular eyes; 

 thorax not greatly attenuated anteriorly, but profusely punctate, with mod- 

 erately large and rather shallow punctures ; elytra arched, nearly three times 

 longer than the thorax when measured over the curved back, furnished witli

slight and faintlv impunctured striae ; the sin-face between the strioj also 



punctured, but very faintly.

HORMISCUS PARTITUS. 

 I'l. S, Fiff. 17. 



A single specimen showing the upper surface of a minute beetle seems 

 to fall in this immediate vicinity. Only a little of the head is shown, pro- 

 truding as a rounded mass in front of the minutely punctate thorax, which is 

 subquadrate with gently rounded sides, scarcely tapering anterior.lv. The 

 elytra at their base, as throughout their basal two-thirds, are together half 

 as broad again as the thorax, and are marked by straight longitudinal rows, 

 of wnich eight are visible on each elytron, of large round punctures, about 

 as distant In each row as the rows are from one another.
