CERAMBYCID.E 28 1 



width to the elytra, distinctly transverse, rounded and inflated at 

 the sides before the middle, coarsely, sparsely punctate, the punc- 

 tures granuliferous, the four spots large, yellow, somewhat diffused, 

 the elytral fasciae narrow, rather diffused, yellowish, the humeri not 

 in the least impressed; antennae (9 ) fully as long as the body; de- 

 pressed pubescence throughout the body short, not at all dense or 

 conspicuous, the surface shining. Length (9) 6.8 mm.; width 2.6 

 mm. California (Island of Santa Catalina), Fall., .catalinae n. sp. 



There is a general similarity of habitus, form and color pervading 

 all the modifications of Ipochus above noted, so that they have 

 been neglected hitherto and all considered asfasciatus Lee., without 

 any sort of discriminative investigation so far as recorded. A closer 

 study reveals considerable diversity however, and I have but little 

 doubt of the validity of the species named in the table. They are 

 generally arboreal in habits and not epigeal as stated by LeConte 

 and Horn. 



It is probable that the Mexican Parmena villosa of Bates, is 

 closely allied to Ipochus, but the sculpture of the body seems to be 

 different. 



Moneilema Say. 

 Monilema Lee. et Horn. 



The species of this genus are numerous though frequently closely 

 allied, and they are but slightly diversified in structural characters 

 as a rule; there are probably fifty or more represented in cabinets, 

 but only very few, having more salient and striking distinctive 

 features, have been described. Those present in my collection may 

 be defined as follows:* 



Subgenus Moneilema in sp. 



First antennal joint acute externally at apex; basal joint of the hind 

 tarsi more elongate; anterior parts smaller when compared 



with the hind body. 



Antennal joints three to five or six annulate with white pubescence. . . .2 

 Antennal joint four alone annulate with white; body much larger; pro- 

 thorax without trace of lateral tubercle 5 



2 Pronotum barely at all punctured except near the base 3 



* I have followed Say in giving the specific names the feminine ending, harmonizing 

 with the general rule for Latin words of whatever derivation ending in a, and as observed 

 in Lema of the Chrysomelidse. The recorded measurements of length extend only to 

 the tips of the elytra.
