CrATOPARIS "? ELUSUS. 

 PI.8, Fig. 40, 



Cratoimris ? eliisiis Scudd., Bull. U. S. Geol. Geogr. Surv. Terr., IV, 763-769 (1878). 



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

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

 to Cratoparis and of about the size of C. lunatus 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, neai-lv three times 

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

 slight and faintly impunctured striae ; the surface between the strias also 

 punctured, but very faintly. 



Length of body, 7.5""'; of thorax, 2.25'""; of elytra, 5.5"'".

HORMISCUS Waterhouse. 



HoRMISCUS PARTITUS. 

 PI. 8, Fig. 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 anteriorly. The 

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

 as br^ad again as the thorax, and are marked by straight longitudinal rows, 

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

 as dista)it in each row as the rows are from one another. 



Length, 2.75""' : of elytra, 1.8"" ; breadth of thorax, 0.9"" ; oftegmina, 

 1.4"".
