174 Mr. G. 0. Champion on the 



third tarsal joint beneath. C. enderleini agrees with C. solox 

 in having no visible scutellum, both doubtless being apterous. 

 The present insect has the general facies of a Simplocaria, 

 except that the elytra are without trace of striae. 



Lathridiidas. 



17. Lathridius maJouinensis, sp. n. 



Elongate, somewhat depressed, moderately shining, the 

 head and prothorax ferruginous, the elytra testaceous, obliquely 

 nigro-bifasciate (the fasciae varying in development, some- 

 times more or less coalescent and leaving only the apex and a 

 humeral patch testaceous), the antennae (the club excepted) 

 and legs testaceous, the terminal joint of the tarsi more or 

 Jess infuscate, the under surface in great part piceous. Head 

 densely, rather coarsely punctate, grooved down the middle and 

 also towards the sides, the eyes small, rounded, the temples 

 about equalling them in length ; antennal club 3-jointed, 

 the terminal joint obliquely truncate at the tip. Prothorax 

 much longer than broad, strongly explanate at the sides 

 anteriorly, deeply constricted and transversely grooved before 

 the base, the caducous membranous margin broad; the 

 surface roughly punctate, bicostate on the disc (appearing 

 deeply sulcate down the middle). Elytra long, oval, some- 

 what acuminate at the tip, extending well beyond the abdo- 

 men, the humeri not prominent; with rows of closely placed 

 coarse punctures, the interstices narrow, 3 and 5, and also 7 

 at the base, costate.

J lab. Falkland Is., Port Stanley (M, Cameron). 



Numerous examples, found on the flowers of an introduced 

 Ule.v, on Dec. 9th, 11)1-4. This species belongs to the section 

 Coninomus, Thorns. Ijfc is much more depressed than the 

 somewhat similarly coloured L. bifasciatus, Jleitt. ( = )iiyro- 

 maculatus, Black b.), from Australia, and has more even, 

 relatively longer, oval elytra, Keitter and Belon have 

 described various allied forms from Chile, but the Falkland 

 insect dots not accord with any of them. This Lathridius 

 may have been introduced into the islands with the plant 

 upon which it was found. Some of them, like L. nodifer, 

 Westw. (=antipodum } White), are cosmopolitan. The genus 

 is not included in Fndcrlein's list, 1912.
