ANTHICIDAE. 2G5 



The mandibles are truncate ; the epistoma separated from the 

 front by a transverse suture ; the maxillary palpi feebly dilated ; 

 the middle coxae are contiguous ; the abdomen of the male has 

 six distinct ventral segments ; the penultimate joint of the tarsi 

 is bilobed, and the claws are suddenly dilated at base into a 

 broad tooth. 



Tribe II.— XYLOPHILI1VI. 



A few small species, found on leaves and flowers, are contained 

 in this tribe ; they have entirely the form and appearance of spe- 

 cies of Anthicus, but are known at once by the emarginate, hairy, 

 and coarsely granulated eyes. None have yet been found in the 

 Pacific district. 



The head is much deflexed, and constricted immediately behind 

 the eyes ; the epistoma is separate from the front ; the neck is 

 very small ; the last joint of the maxillary palpi is large and 

 securiform ; the middle coxa? are contiguous ; the hind coxa? are 

 nearly contiguous, the intercoxal process being very small ; the 

 first joint of the hind tarsi is extremely long ; the penultimate 

 joint is bilobed, and the claws are simple. 



One species, X. Melsheimeri Lee, is remarkable for the antennae 

 of the male being flabellate ; in another species, X. basalis Lee, 

 the last joint of the antennae is considerably longer than the 

 others. I do not feel certain that these should be regarded as 

 generic differences. 



Tribe III.— MACRATRimi. 



Two very narrow, brown, pubescent species of Macratria are 

 found in the Atlantic States, on flowers and leaves. 



The head is deflexed, constricted far behind the eyes, which 

 are oval, and not at all emarginate, somewhat coarsely granulated, 

 and slightly hairy ; the neck is very small ; the epistoma is not 

 separate from the front ; the maxillary palpi are compressed and 

 dilated, with the last joint large and securiform ; the last three 

 joints of the antenna? are longer than the others ; the middle coxae 

 are distinctly separated ; the hind coxa? are nearly contiguous ; the 

 intercoxal process of the abdomen is very small and acute ; the 

 first joint is longer than the others, and the sixth is visible in the 

 male ; the penultimate joint of the tarsi is bilobed ; the first joint 

 of the hind tarsi is very long ; the claws are suddenly and broadly 

 dilated at base.
