[Since writing the above, I have seen in the late Dr. Mason's 

 collection, now at Cardiff, several other $ ? of cyaneus F., without 

 date or locality stated, but supposed to have been taken in Britain.] 



Oryssus ahietimis (cf. Ent. Mo. Mag., March, 1904) certainly 

 occurs at times in these islands, and may possibly be indigenous. But 

 it seems more probable that it is merely a chance visitor, imported in 

 timber from the Continent.

EuDiRCAEA, n. gen. 



Antennae with joint 2 small, not half the length of 3, 3-11 longer than 

 broad, greatly dilated, and compressed, 7-11 tapering, 11 feebly constricted at 

 the middle ; maxillary palpi long, joint 2 elongate-triangular, about as long as 

 4, 3 transverse, 4 elongate, cultriform ; head rather small, vertical ; eyes trans- 

 verse ; prothorax subtruncate at the base, leaving the scutellum exposed, 

 margined laterally from about the middle backward; scutellum flattened, 

 transverse, trapezoidal ; elytra very elongate, parallel ; prosterniim with the 

 ante-coxal portion short, triangularly extended backward between the very 

 large, conical, contiguous coxae, the pleural suti^re obsolete ; intermediate coxae 

 separated by a lanciform mesosternal process ; tibiae each with two long, sxib- 

 equal, simple spurs, the intermediate and posterior pairs notched along their 

 outer edge ; anterior tarsi broadly dilated in <? ; posterior tarsi with joints 1 

 and 2 compressed, much widened in ^ ; penvxltimate joint of each tarsvis short, 

 small, bilobed. 



Type: E. laticornis. 



This genus, including two species, is the Tropical American 

 representative of BapsUoderus Fairm., and Lajjsiloderinvs Ch., differ- 

 ing from these Eastern forms in the non-serrate, more tapering 

 antennae, with almost simple terminal joint, the transverse scutellum, 

 the unnotched elytral suture, the compressed first and second joints 

 of the posterior tarsi, the short, bilobed tliird joint of the latter, the 

 relatively larger second joint to the antennae, etc. The contiguous 

 anterior coxae are as large as in Dapsiloderus, the intermediate coxae 

 separated by a narrow mesosternal process as in Dapsiloderinus ; tlie 

 terminal joint of the maxillary palpi is cultriform, and much larger 

 than in Dapsiloderus. The (J tarsal characters, too. are very pro- 

 nounced in the American insects.
